The 62.5/125 multimode fiber cables are perfect for network deployments. Its zipcord cable type, <0.5dB insertion loss. The strengthening fibers that help protect the core against damage during installation or from being crushed. The coating layer of thicker plastic surrounds the cladding and helps protect the fiber core. The layer that protects the core and causes the neccessary reflection to allow light to travel through the fiber-core segment. The physical component that transports the optical data signal, made up of a continuous strand of glass. The core's diameter is measured in microns.
