1.5 Outdoor Interconnect Cable

The interconnect cable between the Power Inserter Unit and the radio carries the following signals

1. DC voltage to supply power to the pulsAR radio.

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

in excess of the 100 meters (300 feet) of the IEEE Ethernet specification. Figure 1.3 shows the

interconnect diagram for this cable and connector types. Table 1.8 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 E for connector diagrams, part numbers, and

assembly instructions.
