Abstract

Techniques are provided to permit a cable operator to easily daisy-chain the alternating current power distribution from one service group to the next by using a single outdoor passive unit. This is especially relevant for fiber deep Node+0 networks with highly segmented service groups (as compared to traditional hybrid fiber coaxial service groups).

ABSTRACT

Techniques are provided to permit a cable operator to easily daisy-chain the

alternating current power distribution from one service group to the next by using a single

outdoor passive unit. This is especially relevant for fiber deep Node+0 networks with

highly segmented service groups (as compared to traditional hybrid fiber coaxial service

groups).

DETAILED DESCRIPTION

In hybrid fiber coaxial (HFC) networks, the alternating current (AC) power

distribution sometimes needs to be distributed among fiber nodes via daisy-chaining

instead of being directly piped from a central network power supply to each and every node

location. There needs to be a way to pass AC power from one node’s service area to an

adjacent service area without affecting the unique radio frequency (RF) distribution present

on each of the service areas. This has become more desirable with the advent of highly sub-

divided service groups associated with fiber deep N+0 applications.

The coaxial power bridger is a single device that can be used to feed AC power

from one coaxial network to another without commingling the different RF signals that

may be present on each network. The coaxial power bridger operates similar to two back-

to-back power inserters (with the RF connection terminated on each end and the AC

connection tied between each end) so that power may be fed from...
