Field Terminated Vs. Pre-Terminated Fiber Optic Assemblies

by Fiber-MART.COM cWhile there are many options with which fiber optic cables and connectors to choose from, there are really only two major termination solutions: field terminated and pre-terminated. This post is going to break down what the difference between these terminations styles, the advantages and disadvantages, so you can have the best solution for your business and technicians.   What are Field Terminated Fiber Optic Assemblies?   Field termination describes the termination of the fiber optic cable in the field or, after installation has taken place. When these types of cables are terminated, they need to be pulled between two points, then connectors will need to be attached and then connected to a patch panel. In addition, before they can be attached to a panel, connectors need to be attached to each individual strand, and a variety of tools will be needed.    Advantages   Precision Lengths: Because these cables are cut to length before adding connectors,

Fiber Optic Media vs Copper Media

by Fiber-MART.COM Fiber-optic technology is getting more and more popular nowadays in the professional networking world. “Why?” – one may ask. “Is it the distances that signal can travel without a repeater? Or is it the passive components that require no energy to operate?” Both statements are true, however main reasons are potentially unlimited bandwidth (limited only by the speed of light) and immunity to external factors.   Data in the optic-fiber is transmitted by a LED or a laser, and received by an optical detector. Data in single optical cable can travel simultaneously in multiple wavelengths. However that would require multiple lasers transmitting signal, and multiple receivers to accept data at the same time.     Difference in wavelengths is measured in nm (nanometers). Typical data transmission wavelengths are between 850nm and 1550nm.   As it was mentioned before, optical-fiber is more advanced type of cable than copper cable, due to multiple reasons. Extern

Using Multi-duct for FTTH build out a cost-effective option!

by Fiber-MART.COM Yates Engineering Services continues to review and assemble its knowledge base on Fiber to the Home deployments across the nation.  One of the newer trends that we have been studying and deploying is the use of multi-duct.  Multi-duct is simply when 2 or more small ducts are combined in a plastic over sheath.  Two popular versions of multi-duct are a four micro-duct and a seven micro-duct.  The micro duct itself comes in a number of sizes with a 10 mm to 13 mm inside diameter most frequently used.  Both of these sizes can be placed with the same 2” bore or trench that places a single, traditional 1 ¼” duct.  Dielectric  micro-fiber  is then used to populate one of the micro-ducts, leaving many spare paths.  The four-way is a new choice for long haul or trunk backbones, and the seven-way is a good choice for placement in denser areas, where the extra micro-duct can be used for drop paths along the road.    When used in this way, fewer access points, or hand hole

How my Fiber Optic Kevlar Cutter made me look like a hero to my wife

by Fiber-MART.COM Okay, you’re asking “what’s the deal?” Let me tell you a true story and you can judge for yourself. It all started on my wife’s birthday when the kids sent their mother a bouquet of long stem roses. They were red and they were gorgeous, and I was equally impressed that the thorns were removed. So now the plan was to put these flowers into an appropriate vase for everyone to see, fill with just enough water and stir in one of those food packets to keep them fresh.   I always put the packets in and I always wonder whether they really do anything or if the florist just gives them to you to make it seem like he is doing you a favor. Does it work? Would the flowers last the same amount of time without the little packet? Your guess is as good as mine.   Now I go into the closet looking for the right size vase for the flowers, and you guessed it, long stem roses and the vases in my closet don’t match…time to cut the flowers. Well my wife grabs an old pair of sciss

How To Decide What Goes Into A Fiber Prep Kit

by Fiber-MART.COM Kit configuration starts with our marketing department, our staff of engineers and our sales team. Usually it’s the sales team up first explaining the need for a kit for a specific customer or they had an inspiration or a germ of an idea from a tech in the field saying he wished he had a selection of tools in an all-in-one kit. Ideas can originate just about anywhere. All suggestions are evaluated, and one of the first questions posed is there a market for this kit and will anyone care (translation, will anyone buy it)?   Kevin Costner starred in the movie, Field of Dreams. And a voice over kept saying, “if you build it they will come.” We ask, if you build it will the customers come. In the case of fiber prep tools and the need for a kit our marketing department conducted extensive research and found such a need, and with the breadth of line, fiber-mart Tools was positioned to fill it.   Because fiber is ubiquitous and more and more is being installed ever

The Importance of Cleaning and Maintaining Fiber Optic Cables

The Unfortunate Disadvantages of Using Copper Wires

by Fiber-MART.COM Copper wires used to be the number one way to transmit information through a series of underground cables.  And, this worked for a long time–we were used to poor connections, dangerous conditions, and low transmission ranges.  However, that is what led us to discover the usefulness of fiber optic cables.  We’ve since discovered that copper wires are nowhere near as advantageous as using fiber optic cables.  But, what are the serious disadvantages that come with using copper wires in this day and age?  Read on to find out.   This may come as a surprise to many; fiber optic cables seem like the should be much more expensive.  Due to the fact that copper is based within a Latin American foreign trade system, it can cost more to obtain.  Likewise, it doesn’t transmit information nearly as far or as quickly as fiber optics.  This means that, over long distances where it is necessary, copper wire is not practical, cost-wise.  It takes way more cable to complete what

How Fiber Optic Cables Can Help You

by Fiber-MART.COM With fiber optic cables, you’re choosing to upgrade to a more efficient way of completing tasks. A network that runs on fiber optic cables is one that runs smoothly. Instead of using traditional networking techniques, fiber optics have essentially replaced the once dominant wire method. The difference is in the material used to make these fibers. The cables are basically thin strands drawn from molten silica glass. The information that is processed through these is converted into light, which then gives way to the transmission itself. With fiber optic cables, there are a few areas where you stand to benefit, and today we’re going to detail them here.   Internet Connection One of the primary reasons many companies are employing fiber optic cables is due to the overall speed it provides. With this technology, the ability to easily send and receive large amounts of data occurs without a hitch. Looking at previous configurations, larger amounts of data would take

Difference Between Twisted Pair Cable and Coaxial Cable

by Fiber-MART.COM A wire or cable is an indispensable element in communication system for connecting optical devices like optical transceivers, router and switch. Recently the most common cable types deployed in communication system are fiber optic cable, twisted pair cable and coaxial cable. Both twisted pair cable and coaxial cable are copper cables, so what’s the difference between them? This article may help you sort it out.   Twisted Pair   Twisted pair cables as the names implies, consists of a pair of cables twisted together, which has been utilized in telecommunication field for a long time. The twisting can avoid noise from outside sources and crosstalk on multi-pair cables, so this cable is best suited for carrying signals. Basically, twisted pair cable can be divided into two types: unshielded twisted-pair (UTP) and shielded twisted-pair (STP).   twisted-pair   UTP is for UNshielded, twisted pair, while STP is for shielded, twisted pair. UTP is what's

Understanding Polarity in MPO System

by Fiber-MART.COM Understanding Polarity in MPO System     MPO/MTP technology has led to the adoption of 40/100GbE, however on of its challenges is with regards to  proper polarity of these array connections.  Maintaining  the correct polarity across a fiber network enables signals  from any type of active equipment to be  directed to the receive port of a second piece of active equipment – and vice versa. To ensure the MPO/MTP systems work with correct polarity, the TIA 568 standard suggests several methods.    MPO Connector   First on the list is the  MPO connector usually consisting of  12 fibers. 24 fibers, 36 fibers and 72 fibers  Each MTP connector has a key on one of the flat side added by the body. When the key sits on the bottom, this is called key down. When the key sits on top, this is referred to as the key up position.  In this orientation, each of the fiber holes in the connector is numbered in sequence from left to right and is referred as fiber position
