Optical Transceiver Modules for SFP+ applications are the logical evolution to Amphenol’s popular copper line-up of Active andPassive SFP+ Direct Attach Cable Assemblies, according to Nick Blas, Cables on Demand Product Manager. “With millions of Amphenol brand Passive Copper Cables deployed worldwide for SFP+ applications, there’s no doubt that copper dominates the majority of the SFP+ interconnect market today.” Blas notes that despite SFP+ copper’s popularity, some design limitations, such as maximum link distance and cable management, are best remedied by switching to an optical SFP+ interconnect solution.

Amphenol Cables on Demand addressed all of these aforementioned design limitations by releasing its new 10GBASE-SR SFP+ Optical Modules. While nearly identical to copper SFP+ visually, the SFP+ optical module’s advanced integrated circuitry automatically converts the SFP+ port’s default electrical interface to optical, amplifying the resulting optical signal with an efficient VCSEL laser driver and terminated to an integrated duplex LC connector on the rear of the module.

In order to ensure compatibility with your SFP+ switch or host bus adapter (HBA), Amphenol SFP+ Optical Transceiver Modules are subjected to intensive OEM-specific compliance testing so that they may be used as compatible drop-in replacements for their OEM SFP+ optical module counterparts. A complete SFP+ module cross-reference compatibility chart is appended to this press release and key product specs are provided below:

Cables on Demand Guide to Better Wi-Fi: Part Two

Guide to Better Wi-Fi Part Two:   Tools of the Trade


 

Part one of out exclusive Guide to Better Wi-Fi served as an introduction to topic, with particular emphasis placed on the history, environmental and channel characteristics of Wi-Fi technology.  The challenges encountered by the typical Wi-Fi network user and/or administrator are profuse; primarily due to extreme overcrowding of the prominent 2.4 GHz 802.11B/G/N Wi-Fi band. 

 

Wherever Wi-Fi signal density is classified as medium to high, such as urban and suburban housing, commercial districts, and educational campuses, problems such as wild fluctuations in wireless signal strength, dropped connections, sluggish response times and unreliable download speeds become par for the course.  Unfortunately, such conditions have become so pervasive in the technologically sophisticated society we live in today, many Wi-Fi adopters have simply come to believe a subpar wireless networking experience is acceptable.

 

Well, the good news is…it doesn’t have to be that way!  There are many tips and tricks out there to be tried; many of which will cost you absolutely nothing to try.  Before we dive into specific solutions, we need to talk about what I consider to be the “Tools of the Trade”.  Perhaps the most critical tool of all is the ability to conduct a little Signals Intelligence (SIGINT) on the Wi-Fi band(s). 

 

While this may sound complicated and expensive, Wi-Fi SIGINT is a surprisingly simple endeavor.  Essentially you want to turn your desktop PC, laptop or tablet into a fully functional Wi-Fi Scanner.  You may be familiar with the once popular police scanner, a stand-alone device capable of scanning multiple radio frequencies in a short period of time; enabling a user to listen to fast-changing police, fire, military or aircraft communications.

 

Luckily, your computer or tablet’s Wi-Fi adapter can be easily re-purposed as a Wi-Fi scanner while remaining to perform its principal duties of sending and receiving Wi-Fi network traffic with a connected wireless access point.  In fact, your Wi-Fi adapter is constantly scanning or “roaming” the Wi-Fi band looking for the best signal to latch onto.  Because this activity is being performed in the background with the assistance of the operating system, you may never be fully aware of its built-in scanning capacity.

 

That’s where my favorite Wi-Fi Tool of the Trade comes into play:

 

InSSIDer

 

 

 

 

 

While there are multiple versions of metageek’s InSSIDer on the market for the home, office, or handheld device, this article series will specifically address InSSIDer Home version 3.1.2.1.  This version, designed for use on any Windows PC, laptop or tablet, is absolutely FREE to use for home and related-sized Wi-Fi networks.  It’s extremely easy to use, provides a wealth of valuable data and even offers direct tips under select circumstances to improve your Wi-Fi network performance.

 

To help save our fellow blog followers the time and effort to locate this copy of InSSIDer, we’ve posted the InSSIDer MSI windows installer package on our server for a quick and easy download!  Simply click on the link below to download the installer package.

 

 

 

 

Once you’ve installed InSSIDer on your system, congratulations!  You’ve successfully converted your computer or tablet into a full-function Wi-Fi Scanner.  We will dive into InSSIDer’s “insides” in the next article in this series.  In the meantime, there are a few other critical tools of the trade that you will need in order to implement the recommended changes to your Wi-Fi network configuration.

 

InSSIDer is simply one piece of the puzzle.  You cannot rely on its readings alone to optimize your Wi-Fi network.  You will also need a reliable network speed test platform to properly test for the maximum upload and download speeds your hardware will support.  They can also provide valuable data about your network’s latency and signal skew performance.  My personal favorite:

 

OOKLA Speed Test 

 

 

To use the OOKLA Speed Test, simply type the following web address into any web enabled device:

 

http://www.speedtest.net

 

 

OOKLA also makes a great stand-alone version of their popular speed test in the form of an Android App.  This version is better suited for smaller sized devices such as smart phones and tablets.  Download a free ad-supported copy by searching for “OOKLA speed test” in the Android Market / Google Play store.


 

Now that you have access to these important Tools of the Trade, it’s time to start scanning your home or office Wi-Fi environment and optimizing your Wi-Fi network.  We will continue the discussion from here in part three of this multi-part Guide to Better Wi-Fi — coming soon exclusively at CablesOnDemandBlog.com.

10-Gigabit Ethernet Backbone Interface Options: Which One Should I Choose?

2 Replies
 
This week’s question comes to us from Chris in New York:
 
We plan to upgrade our network backbone to 10-Gigabit Ethernet.
 
What interconnect platform should we use? 

 

 

Thanks Chris for your question.  This topic comes up quite frequently for a number of reasons.  Not too long ago, only medium to large enterprises could viably afford to make the leap to 10-Gigabit Ethernet on their networks.  That is simply no longer the case today.  Not only are there hundreds of 10GbE-ready switch manufacturers on the market today, but there are also multiple interconnect platforms available that support the 10-Gigabit Ethernet protocol.  As you can see by the timeline above, 10-Gigabit Ethernet has already surpassed the point of being a widespread and mature technology; ensuring low implementation costs.

Because this is a lengthy topic, I will need to divide it up into two segments.  The first segment will focus on the most obvious interconnect platform for 10-Gigabit Ethernet applications: 10GBASE-T. 10GBASE-T, also referred to as IEEE 802.3an-2006, is essentially 10-Gigabit Ethernet over standard twisted pair (UTP or STP) copper wire, such as Category-6 (CAT6) Cables and Category-6a (CAT6a) Cables.  A great number of networks have featured a 1000BASE-T (Gigabit) backbone using CAT6/CAT6a. Transmitting data at 1.0 Gbps speeds over this cable type is fairly easy from a hardware perspective and was therefore a highly implemented option for network administrators.

  

 Pictured: Typical Gigabit Ethernet (1000BASE-T) Network 

 

However, the entire equation changes dramatically when you have to increase the data throughput by a factor of ten from 1.0 Gbps up to 10.0 Gbps.  At this high 10-Gigabit speed, a whole bunch of negative performance ramifications come into play that were simply ignored or non-existent in the case of Gigabit Ethernet.  Some of these factors include:

Bandwidth:  To transfer data at 10-Gigabit speeds, the required cabling must be designed to support a substantial amount of bandwidth.  To operate effectively over a sizable distance (up to 100 meters or 330 feet), Category-6a Cabling must be used thanks to its inherent support of up to 500 MHz of bandwidth.  To compare, regular Gigabit Ethernet (1000BASE-T) can operate with plenty of headroom using a 100 MHz bandwidth capable Category-5e (CAT5e) Patch Cable.  To increase bandwidth, you have to operate at extremely high frequencies.  High frequencies behave quite differently from lower frequencies, thus demanding a more capable interconnect design.

Bandwidth can be visualized as a pipe (see below).  A high-bandwidth capable interface, like 10-GbE, requires a thicker data pipeline (backbone) so that all of the high-speed data can stream through it without resistance. If you try and force high-bandwidth data through a low-bandwidth pipe, you will witness a massive slowdown in data throughput. Sometimes, like in real life, the pipe will burst and the interface will shut down.  This is why maintaining high bandwidth is so critical.    

 
 
(Pictured: Bandwidth Conceptualized via a Pipe) 
 

 

Alien Crosstalk:  Alien Crosstalk, also known as ANEXT, is when signals from outside sources, such as other patch cables in close proximity or other localized sources of electromagnetic interference (EMI/RFI) like lighting, power transformers, wireless access points, etc., interfere with the 10-Gigabit Ethernet signal that travels down the cable.  Regular Category-6 (CAT6) Cables do not address the issue of ANEXT directly and as a consequence can only support 10-Gigabit Ethernet at distances up to 50 meters (166 feet).

 
 
  
(Pictured: Cables Affected by Alien Cross-Talk)

 

 

To mitigate the problems associated with bandwidth and ANEXT, Category-6a Cables utilize three principles:  Pair Separation, Shielding and Tight Tolerance.  Pair separation involves placing a plastic x-shaped insulator in the middle of the cable itself.  This keeps a designated amount of spacing between the wire pairs, thus assisting with Near-End Cross-Talk (NEXT) and maintaining proper cable impedance.  Shielding involves shrouding the entire cable in a concentric ring of Aluminum foil.  This prevents outside EMI/RFI interference and related Alien Cross-Talk (ANEXT) from wrecking the signal.  Tight tolerance simply means that Category-6a (CAT6a) Cabling is designed and assembled with minimal tolerance for out-of-specification characteristics such as maintaining a perfect number of cable twists-per-inch. 

Now that the technical specifics are out of the way, how do we reach a determination as to whether 10GBASE-T (10-Gigabit Ethernet over Twisted Pair) is the right choice for your network upgrade?  I like to look at three critical cost factors.  The more dollar signs shown, the more expensive the cost.

 

Critical Factor #1:  Switch Cost 

  

  

 

In all likelihood, your largest upgrade expense is going to come from the cost of updating all of your switches to 10-Gigabit Ethernet compliant models.  Unfortunately, this is where 10GBASE-T fairs the absolute worst.  Development was significantly delayed on 10GBASE-T hardware, specifically the silicon chipsets that power the switches.  10GBASE-T proved far easier to develop on paper than it did in the real world.  As a consequence, while 10GBASE-T products are just barely trickling out to the market from a select few manufacturers, other 10-Gigabit Ethernet interface standards, such as SFP+ Direct Attach and 10GBASE-CX4 have taken hold.

 

Critical Factor #2:  Cable Cost

 

  

 

This is where the 10GBASE-T interface dominates hands-down.  Cables for 10GBASE-T are the absolute cheapest option because all you need to purchase are Category-6a (CAT6a) Patch Cables.  At Amphenol Cables on Demand (http://www.CablesOnDemand.com), we stock a variety of Category-6a (CAT6a) Patch Cords in your choice of length and color at prices starting at only $3.16 (even less when on sale).  This is perhaps 90-95% cheaper than the other aforementioned interface options!

  

Critical Factor #3:  Power Consumption

 

    

 

Power Consumption is the Achilles Heel of 10GBASE-T.  The fact is, the engineers who came up with the Ethernet standard decades ago never imagined that inexpensive twisted pair communications cable would support the blazing fast speeds of today.  As such, engineers have had to squeeze 10-pounds of bandwidth into a 1-pound bandwidth bag.  This comes at a price.  To make up for the cable’s inherent deficiencies, the switch has to do the heavy lifting by using extra power to sort through all of the signal errors and lost packets that will naturally occur over twisted pair cabling.  As such, 10GBASE-T switches are both power hungry and heavy in terms of heat dissipation, posing a major issue from an environmental management perspective.  There’s no such thing as a “Free Lunch” as they say; in this case the free lunch being cables that cost 90-95% less than other options!      

 

Conclusion:

While 10GBASE-T, 10-Gigabit Ethernet over Twisted Pair, has been hyped for years as the inevitable de-facto solution for 10-Gigabit networks, reality simply eliminates this possibility.  Delayed development, cost overruns, limited suppliers; combined with high switch and power consumption costs makes 10GBASE-T an unattractive option. The only upside to 10-Gigabit Ethernet over CAT6/6a  is the fact that CAT6/6a Cables are so inexpensive.  I can’t in good conscience recommend 10GBASE-T for your network upgrade under these circumstances.  

 

Recommended?  NO

 

Stay tuned for the follow-up blog to this question in which we will discuss two other 10-Gigabit Ethernet interface choices: CX4 and SFP+.

The Cable Guy

Question: How Do I Know How Many Amps Your Cable(s) will Handle?

1 Reply

 

This week’s question comes from Rick H. in Iowa:
 
Question:  How can I tell what the maximum supported amperage capacity is for your cables? 
 
 
Answer:  
 
Thank you for the excellent question Rick!  Understanding the voltage and current limits of your cable(s) is absolutely critical to maintaining a safe transfer of electrical power between your devices.  All cables feature some degree of resistance to electrical energy.  
 
When electricity is forced to flow up against this resistance, it releases energy into the environment in the form of heat.  When cables are very thin, i.e. 30 AWG or smaller, the cabling cannot dissipate that heat energy into the environment fast enough, leading to a fundamental breakdown (failure).
 
The electrical breakdown of a cable assembly is not a pretty sight. During my younger years when my electronics expertise was in its infancy, I once made the horrible mistake of wiring a 12V DC switch incorrectly on a project box.  The switch connected a 12V lawn mower battery to a radio transmitter.  
 
Upon engaging the mis-wired switch, the connection created a short circuit between the negative and positive terminals of the battery — effectively dumping up to 100 Amps of current down some 18 AWG wire.  I watched in horror as the wire literally melted from the inside out, causing a flash-fire with the PVC wire insulation melting away like candle wax!  The melted wire dripped onto the carpet and nearly started a house fire.  
 
Example: Electric Blanket Fire
 
Fortunately, I was able to disengage the switch quickly before things got even worse, but literally in a matter of seconds, significant damage was done.  I learned a hard lesson that day about just how important current-handling capacity can be when it comes to cables.  What would happen if a whole bundle of wires ignited and went unnoticed?  Besides the fire risk, the burning PVC insulation contains toxic fumes that can prove deadly in their own right.
 
To prevent disaster, you should always select a cable based on the most conservative of safety ratings in mind.  The extra margin of error can be a life-saver.  So what do you need to know first?
 
#1:  You Must Know the Wire Gauge (AWG) of the Cable!
 
This value is imperative.  Our popular D-Sub Cables for instance tend to use 26 AWG insulated wire in their designs.  They are often used in custom projects and fed with a variety of both power and signal data.
 
American Wire Gauge (AWG) Chart

 

 
#2:  Is the Wire Bundled or out in the Open Air?
 
This, believe it or not, makes a huge difference.  When a wire is stand-alone and exposed to the open air, the movement of air around the cable will help cool it down, thus allowing for the transfer of more current.  
 
Example of Chassis Wiring (Free-Air)
 
When a wire is alone and exposed in free-air, we refer to it as:
 
Chassis Wiring
 
Example of Power Transmission Wiring (Bundled)
 
When a wire is bundled together with other wires, we call it:
 
Power Transmission Wiring
 
Chassis wiring refers to the wiring often found inside the chassis of an electronic device where you may have one wire in free-air that jumps from a connector on the outside of the chassis to a connector or PC board on the inside.  Again, because it is in open air, it can handle more current for its given size. 
 
Power transmission wiring refers to any wiring that is bundled together.  This is the figure you generally need to worry about most as most of the cable assemblies we make at Cables on Demand feature more than one wire bundled together.  Note: This rule applies to all bundled cable types, even those you would normally associate with data transfer and not power.  
 
As an example, if you were to open up a typical outdoor rated power extension cord, it would have three wires bundled together (hot, neutral and ground).  Since they are bundled and sealed off in a cable jacket, less current can flow through them safely.   
 
The Current Handling vs. Wire AWG Chart
 
The chart below will tell you the maximum recommended current handling capacity (Amps) for a given wire gauge in both Chassis Wiring and Power Transmission Wiring versions.  Remember to choose the Power Transmission Wiring value for most cables purchased through us and other cable vendors (bundled wire).

How Can I Extend the Length of my Logitech Z623 Satellite Speaker Connection?

Leave a reply
New “Ask the Cable Guy” Blog Question:
How do I Extend my Logitech Z623 Speaker System?
 

 
(Pictured: Rear Panel of a Logitech Z623 Satellite Speaker System)
 
 
Lou from Minnesota has approached us with an urgent question related to how to extend the connection on the back of his Logitech Z623 THX-Certified satellite speaker system. This topic comes up quite frequently because there is a lot of confusion out there about the connection type in question: d-subminiature or “d-sub” for short. 
 
This question extends beyond any single particular brand or model.  Many manufacturers will use this same High Density 15-pin d-sub interface (aka HD15 or DB15HD) in their own speaker and HTIB (Home Theater in a Box) designs.  You can see the HD15 male connector in the picture above of the Logitech Z623, where it is labeled as “Right Speaker”.
 
                
 (Left: Regular HD15 D-Sub)                    (Right: VGA HD15 D-Sub)
 
 
The speaker systems that use the HD15 d-sub interface tend to already come with some form of HD15 d-sub cable in the box, but what happens if you lose it or need to extend it in any way?  A proper HD15 d-sub cable will solve that problem — but it has to be the correct choice for the application. 
 
In the pictures above, can you really tell the difference between the regular HD15 d-sub on the left and the VGA HD15 d-sub on the right?  They both have 15 pins.  They both feature 3 rows of 5 pins each in a staggered arrangement.  They both are contained within the same D-shaped housing.  However, the similarities end there once you explore the insides of these cables.
 
  
 (Pictured Above: Internal Pin Arrangement of Regular D-Sub)
 
 
First, let’s look at the regular HD15 Cables presently available at Cables on Demand.  The drawing above for our Deluxe Series HD15 15-pin D-Sub Cable shows that the inside features 15 identically sized wires, all connected in a “straight-thru” pin-to-pin configuration (i.e. pin 1 routes directly to pin 1 on the opposite end of the cable).  This simple arrangement is primarily designed for the transfer of low-speed data, i.e. RS232 serial port communications.
 
 
(Pictured Above: Internal Pin Arrangement of VGA Monitor D-Sub)
 
 
Next, let’s take a look at the VGA Monitor HD15 Cable presently offered by Cables on Demand.  The drawing above for one of our Premium VGA HD15 D-Sub Cables is radically different from the regular HD15 cable shown previously.  First, you will notice that a VGA HD15 Cable is not made of 15 identically-sized wires. 
 
Instead, it consists of three different coaxial cables (used for RGB video signals), surrounded by several smaller wires.  Also, while this cable type does feature “straight=thru” pin-to-pin wiring, it is not wired in order, i.e. the center pin of one of the coaxial cables goes to pin 1 and the shield return line goes to pin 6.
 
 
So now that we know the differences between the two HD15 D-Sub Cable types, which one is appropriate for extending a speaker system like the Logitech Z623 pictured above?  The answer is the first cable profiled: the “regular” data-grade HD15 d-sub cable.  While these regular d-sub cables are generally used for data transfer, one can think of audio as an analog form of data.  A good rule of thumb: regular d-sub cables are generally beige or grey in color, whereas VGA d-sub cables are generally black in color.
 
The same wire used in our regular d-sub cable is also used in a variety of audio cables, such as speaker wire and instrument cables.  As long as the d-sub cable is shielded, which all of our cables are, it can effectively transfer audio without the fear of noise entering the connection.  The other HD15 d-sub cable type we profiled, the one designed for VGA video use, will simply not work because audio signals are not designed to transfer over coaxial cables!
 
 
Now that you know which cable type to get, head on over to www.CablesOnDemand.com today and search for part number CS-DSDHD15MF0.  Alternately, you can simply click on the image above or link below to go directly to the product.  Our 15-pin (HD15) Deluxe HD D-Sub Cable (Male/Female) can effectively extend your satellite speaker system by up to 25 feet — a vast improvement over the ~ 6 to 10-foot length cable included with the satellite speaker system!
 
 
For cases where the speaker system is installed in an environment more prone to interference, or in cases where you need to extend the speaker system by up to 50 feet, we highly recommend taking a look at our 15-pin (HD15) Premium HD D-Sub Cable (Male/Female) (pictured above).  Our Premium HD15 D-Sub Cable (part number: CS-DSPMHD15MF) features double shielding (Aluminum Foil + Aluminum Braid), helping to preserve the audio signal over a longer distance.  For extensions of 25 feet or less, our Deluxe D-Sub Cable with its Copper Foil Shielding will work just fine. 
 
If you have any additional questions regarding the huge variety of genuine Amphenol brand d-sub cable products available at www.CablesOnDemand.com, please feel free to give us a call at 1-866-223-2860 or e-mail: [email protected].
