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.
So how can fiber optic be up to a thousand time faster than copper? Why is fiber optic better?
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.
The layers of fiber optic cable
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.
Two types of fiber optics
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.
