Multiplexing Basics by Fiber-MART.COM When you need to carve up an expensive resource (such as an active fiber route) into pieces, multiplexing is the way to go. What is multiplexing, you may ask? It's the process by which multiple signals are combined into a single signal, then split back into pieces upon arrival.   There are lots of types of multiplexing. The most simple is space division where the signal carriers are literally held separate by some kind of insulator (like CAT5 or telephone wire.) Time division multiplexing involves using a timer on either end to determine which signal the carrier is carrying. Core-division multiplexing (CDM) uses a code followed by data to specify which signal is being carried. Finally, frequency-division multiplexing (or in the  fiber optic  world, wavelength division multiplexing) involves sending signals over several distinct frequency ranges over a carrier.   The easiest way to think about this is in terms of li...

THE INS AND OUTS OF HDMI SPLITTERS by Fiber-MART.COM The topic today is going to be HDMI splitters. I guess we should start with the basics. An  HDMI splitter  allows you to split one HDMI source signal to two or more outputs. Most HDMI splitters are 1:2, meaning you start with one source and can split the signal into two. We offer other configurations that will support just about any situation. Including even things like sports bars with many displays. You might use an HDMI splitter to duplicate the signal from your cable box so you can watch it on two televisions. An HDMI splitter is not to be confused with an HDMI switch. The most popular question I get on a day to day basis would be just that. The difference between an HDMI splitter and an HDMI switch. Again, an HDMI splitter allows you to send a signal from 1 source to multiple displays and an HDMI switch allows you to plug in multiple HDMI sources (Blueray, Cable/Sat box, etc.) to a display. Using a switch is comm...

MTP/MPO SOLUTIONS by Fiber-MART.COM Data centers and ever-expanding server clusters have created a huge demand for more bandwidth and more space efficiency. Multifiber Push-On (MPO) connectors have answered the call and provide up to 24 or more fibers in a single connector pushing up to and beyond 100Gbps data transmission. The best part is that the connector takes roughly the same space as a single simplex SC connector. MPOs are paving the way for increased data transmission speeds and rack density.   MTP® is a registered trademark of US Conec, marketed as a “high performance   MPO connector  with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors.” MTP and MPO are often used interchangeably and MTP is considered a generalized trademark. Both MTP and MPO are available with standard or elite / low loss options. fiber-mart.com terminates our cables with both MPO and MTP connectors, so pl...

What Is an Ethernet Cable? by Fiber-MART.COM An  Ethernet cable  is one of the most popular forms of network cable used on wired networks. Ethernet cables connect devices together within a local area network, like PCs, routers, and switches.   Given that these are physical cables, they do have their limitations, both in the distance that they can stretch and still carry proper signals, and their durability. This is one reason there are different types of Ethernet cables; to perform certain tasks in particular situations.   What an Ethernet Cable Looks Like   There's a picture of a few Ethernet cable ends on this page. It resembles a phone cable but is larger and has more wires.   Both cables share a similar shape and plug but an Ethernet cable has eight wires and a larger plug than the four wires found in phone cables.   Ethernet cables of course plug into Ethernet ports, which again, are larger than phone cable ports. An E...

What should I do to maintain my fiber? by Fiber-MART.COM There are many ways of being proactive when it comes to fiber plant. However, because of the durability and low maintenance requirements fiber stewards are frequently rolling the dice and taking a wait and see attitude.   Here are a few ways you can get in front of problems.   Third Party Testing Services: My wife's a teacher, and she doesn't let her kids grade their own tests. However, we IT professionals think little about separating the conflict of interest in having the same individual install and test installations or performance. I have been in way to many closets to think this is a waste of effort. The craftsmanship of some fiber installations leaves much to be desired.   Fiber Optic Testing  and Documentation (OTDR, PM & LS) 1.Require a bi-directional OTDR trace 2.Require a PM & LS test to verify core power levels 3.Require an image of the connector endface prior to te...

Does Optical Fiber Have You Tied in Knots? by Fiber-MART.COM At the upcoming PowerGen trade event in Orlando , OFS is proud to demonstrate HCS® (Hard Clad Silica) optical fiber, cable and field termination technology. Unlike telecommunications grade  optical fibers , you can tie our products in knots. While we don’t recommend this in practice, seeing it first hand will help you understand just how rugged these industrialized glass optical fibers are. HCS technology was developed for harsh environments like those found in electric utility installations. HCS optical fibers provide enhanced strength when compared to traditional telecommunications optical fibers. Cables produced with HCS fibers are ideal for utility environments where installations in climate controlled buildings cannot be guaranteed. If your installations are subject to fluctuating temperatures, high vibration, industrial chemicals, UV exposure, electrical noise and difficult conditions for connectorizing, HCS ...

What is the “Cloud” and why do I need Fiber to get there? by Fiber-MART.COM Cloud computing is one of the hottest buzzwords in technology. It appears 48 million times on the Internet. But exactly what is cloud computing? In general terms the cloud refers to using a network of remote servers hosted on the Internet to store, manage and process data, rather than a local server or a personal computer. According to research by Nasuni, there is over 1 Exabyte of data currently stored in the cloud. Okay if you are not familiar with Exabyte that equates to 1,073,741,824 Gigabytes of data. And this number is growing exponentially every day.   Technology has evolved almost immeasurably in the past several decades. To access the tremendous amounts data we need  fiber networks  that can carry Terabits—one trillion bits per second. That is an enormous amount of information passing at the speed of light through this one strand of fiber the size of a human hair.   ...

HOW FIBER OPTICS WORK by Fiber-MART.COM Fiber optic cables  are used everywhere to connect our modern world and are able to send information across countries and vast oceans, but how do they work? Before we get too stuck in to the more technical stuff, why not check out the video below for a nice, simple summary of how it all comes together.   How They Work Fiber optics are fairly simple to understand on a basic level. Essentially information in the form of light is sent from one place to another, this is generally done through fiber optic cable. The beauty of this comes from something known as Total Internal Reflection (TIR), what this means is that the light is able to be sent through a flexible fiber optic cable by simply ‘bouncing from one surface to another’ until it reaches it’s destination.   Reflection vs Refraction   Any time light strikes a surface it can either be reflected from it (reflection) or pass through it (refraction). The ke...

Introduction of Category 6 Ethernet Cables Category 6 (CAT6) is an Ethernet cable standard defined by the Electronic Industries Association and Telecommunications Industry Association (commonly known as EIA/TIA). CAT6 is the sixth generation of twisted pair Ethernet cabling.   How  CAT6 Cable  Works Category 6 was designed to support Gigabit Ethernet data rates (1 gigabit per second - Gbps). It additionally can support 10 Gigabit Ethernet connections over a limited distance (technically, 50 meters or 164 feet for a single cable).     CAT6 cable contains four pairs of copper wire and utilizes all of these pairs for signaling in order to obtain the higher level of performance.  Other basic facts about CAT6 cables:   Ends of a CAT6 cable use the same RJ-45 standard connector as previous generations of Ethernet cables.   Printing along the length of the cable sheath identifies it as "CAT6."   An enhanced version o...
