2.2.6Cable Type

The PWR-AVIS jacks are designed to accept patch cords made up of 735A type mini coaxial cable equipped with little coax plugs (LCP). Equipment (IN and OUT) cable is dependent upon service or bandwidth of the associated equipment. Video equipment requires 734S1 or equivalent cable, equipment operating at intermediate frequencies (IF) and radio frequencies (RF) require HEC-2 or equivalent type cable. All cables should be 75-ohm coaxial with tinned copper shield. The recommended maximum length of cable between NEs is shown in Table 1. Cables are available with F or BNC connectors factory pre-terminated on one end and a stub end on the opposite end. The stub end can then be field connectorized using the appropriate connector to fit the NE Interface. This method of cabling provides exact length cables and minimizes storage congestion. If the use of pre-terminated cables is not desired, connector kits with installation procedures are available from ADC for field termination.
