L1-Fiber
Layer 1 - Fiber Optics Fiber Optics uses light (visible and non-visble) to transmit communication signels All Fiber optic cables are made up of sever important compmen Core: is ushally made up of very thin crystal clear glass or platic that allows light to pass through. Think of the core as a guide to help ensure the light passes through to the other side. Cladding: is ushally made up of ### which has a high index of refraction, meaning when light its the cladding at the right angle is it reflected (refracted) back into the core....
