Fiber types are identified by the diameters of the core and cladding, expressed in microns. Multimode fiber is available in two sizes, 62.5 or 50 microns, and four classifications: OM1 (62.5/125 µm), OM2, OM3, OM4 (50/125 µm). The diameter of a single mode core is 9µm.
What is OM3 and OM4?
One big difference between OM3 and OM4 multimode cable is that OM4 provides a higher modal bandwidth 4700 MHz·km compared to 2000 MHz·km of OM3. ... The higher bandwidth available in OM4 means a smaller modal dispersion and thus allows the cable links to be longer with lower losses or attenuation.
What is armored fiber cable?
Armored fiber optic cable consists of a cable surrounded by a steel or aluminum jacket which is then covered with a polyethylence jacket to protect it from moisture and abrasion. It may be run aerially, installed in ducts, or placed in underground enclosures with special protection from dirt and clay intrusion.Apr 2, 2015
What are the 2 types of fiber optic cable?
There are two primary types of fibre – multimode and singlemode. Multimode fibre can carry multiple light rays (modes) at the same time by having varying optical properties at the core; essentially light travelling the shortest path (down the middle) travels the slowest.
How do you cut armored fiber optic cable?
Bend the cable about 10 inches from its end and squeeze with your hand until the coils of the armor come apart. If you can't do this by hand, use pliers or employ another cutting method. Firmly grip the cable on each side of the cut and twist until the split-apart armor coil pops out, away from the wires.Jul 22, 2015
What is 6 strand fiber optic cable?
6 FIBER CABLE - MULTI MODE 62.5/125 It is composed of 6 multimode fibers (62.5 micron core) inside an Aramid yarn wrapped in a black PVC outer jacket. Multimode fiber is optimized to work with fiber optic equipment using light wave lengths of 850nm (nanometers) or 1300nm. The cladding diameter is 125 microns.
What is fiber optic strands?
Fiber optics (optical fibers) are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances.
How many strands are in a fiber optic cable?
Each cable can be made up of as few as two strands or as many as several hundred. The strands, each only one-tenth the width of a human hair, are capable of transmitting around 25,000 telephone calls each.Dec 19, 2018
How fast is OM3 fiber?
10 Gb/s
Is OM4 faster than OM3?
The real difference between OM3 and OM4 multimode cable is that OM4 provides a higher modal bandwidth--4700 MHz·km compared to 2000 MHz·km for OM3. This means that OM4 can transmit more information within the same distance.Jul 14, 2016
