By now, everyone knows that fiber optic cables are considerably faster
than copper. But did you ever ask why? Fiber optic transmits light,
while copper conducts electricity. The signal in fiber optic patch cord
travels through glass at two thirds the speed of light. Impressive,
isn’t it? But wait a second! The speed of electricity traveling through
copper is fast too. Actually faster than fiber – up to nine-tenths the
speed of light.
Indoor optical fiber cable
The
bandwidth is the key. It allows greater capacity of data transmission –
it can transfer from minimum 10 Gbps up to unlimited amounts (if you
take into consideration how fast the technology is developing).
Fiber
optic is considered to be considerably faster than copper because its
signal is not affected by time or weather degradation.Hair-thin strands
of glass or plastic fiber are used to send light signals. The light
travels to the core, the center of the fiber optic. The core it is
surrounded by the cladding, an optical material that traps in the core,
using the “total internal reflection” technique. A primary buffer
coating protects the fiber from moisture or other damage. The level of
protection is strengthened by the cable, which holds the fiber and the
strength members inside and it is covered by a jacket.
Single mode
cables are designed to carry light directly down the fiber. It is a
single strand of glass fiber and has a diameter of 8.5-10 microns.
Because it has one mode of transmission, it will propagate 1310 or 1550
nm.
Multimode patch cords have a bigger diameter, typically 50-100
microns for the light carry component. Over medium distances, multimode
fibers give high bandwidths at high speeds. Light waves are dispersed
into numerous paths, or modes, as they travel through the cable’s core
typically 850 or 1300nm.PeakOptical manufactures indoor and outdoor
fiber optical cables and patch cords. Our cables are available with all
commonly used terminations and in all lengths regardless of order
quantity.
Our portfolio furthermore includes a wide range of spare connectors, adapters, pigtails, and attenuators.
