2.4 Outdoor Interconnect Cable

The interconnect cable between the Power Inserter Unit and the AR24027 carries the following

signals

1. DC voltage to supply power to the AR24027.

2. 10/100 Base-T Ethernet data.

Both these signals are carried in a single CAT 5 cable. The system is designed to allow cable lengths

up to 100 meters (300 feet). Figure 2.3 shows the interconnect diagram for this cable and connector

types. Table 2.7 lists a few part numbers and sources of appropriate CAT 5 cable for this application.

AFAR Communications Inc. carries several pre-made cables of different lengths. See Appendix D

for connector diagrams, part numbers, and assembly instructions.
