Cisco Node

A node is part of the Hybrid Fibre-Coaxial cable network. Specifically it is the part that translates between fiber and coax (light and RF) as fiber is used to extend the area that a single head end or hub can cover beyond what can be transmitted over RF on coax with amplifiers. The node is part of a two way transmission path and the corresponding upstream is often just called the headend laser which can also be located in the hub site.
