Multimode Fiber Optic Cable
No CommentsToday, multimode fiber optic systems are lagging behind singlemode systems in terms of growth. In addition to supporting high data throughput, singlemode systems are attractive because they are easy to upgrade and help to “future proof” installations. Nonetheless, multimode fiber still gets plenty of coverage in any fiber optic cable guide. Why? [ Continue reading…]
What is Fiber Optic Cable?
No CommentsThe world of telecommunications is rapidly moving from copper wire networks to fiber optics. Optical fiber is a very thin strand of pure glass which acts as a waveguide for light over long distances. It uses a principle known as total internal reflection. Fiber optic cable is actually composed of two layers [ Continue reading…]
7 Advantages of Fiber Optic Cables Over Copper Cables
No CommentsWhen you’re planning a new network cable installation or considering upgrades to an existing network, you might want to consider using fiber optic cables. Network fiber cables have some definite advantages over copper cables. Copper cables were originally designed for voice transmission and have a limited bandwidth. Fiber optic [ Continue reading…]
What is DWDM and Why is it Important?
No CommentsIt has been almost 20 years since DWDM came on the scene with Ciena’s introduction of a 16 channel system in March of 1996, and in the last two decades it has revolutionized the transmission of information over long distances. DWDM is so ubiquitous that we often forget that there was a time [ Continue reading…]
dense wavelength division multiplexing (DWDM)
No CommentsDEFINITION dense wavelength division multiplexing (DWDM) Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber, with each signal carried at the same time on its own separate light wavelength. Using DWDM, up to 80 (and theoretically more) separate wavelengths [ Continue reading…]
What is fiber to the x (FTTx)?
No CommentsFiber to the x (FTTx) is a collective term for various optical fiber delivery topologies that are categorized according to where the fiber terminates. Optical fiber is already used for long-distance parts of the network, but metal cabling has traditionally been used for the stretches from the telecom facilities [ Continue reading…]
What do Cat5e, Cat6, and Cat6a have in common?
No CommentsThey each utilize 4 twisted pairs in a common jacket. They use the same style RJ-45 jacks and plugs. And, they are each limited to a cable length of 100 meters including the length of the patch cables on either end of the link. The parts are interchangeable, so you [ Continue reading…]
How to Inspecting Fiber Optic Cables by Fiber-MART.COM
No CommentsVisual Inspection Of Connectors With A Microscope Visual inspection of the end surface of connector ferrules with a microscope is used for finding dirt or scratches on fiber optic connectors and inspecting polish-type connectors during the termination process to find possible defects. This requires a microscope which has a [ Continue reading…]
Which Fiber Optic Connector should you use?
No CommentsThe network cabling industry’s fiber optic manufacturers over the last few decades have been on a constant mission to develop the better fiber connector. This means lower cost, lower dB losses, easier to terminate out in the field. There have been over 100 connectors developed over the years but a [ Continue reading…]
