7-2 InterReach Fusion Installation, Operation, and Reference Manual
CONFIDENTIAL D-620610-0-20 Rev F
NOTE: Faulty cabling is the cause of a vast majority of problems. All CATV cable
should be tested to TIA-570-B specifications.
7.1.1 Component Location Requirements
Fusion components are intended to be installed in indoor locations only.
If outdoor installation is desired, such as a parking garage, the Fusion components
must be installed in the appropriate environmental enclosures.
7.1.2 Cable and Connector Requirements
Fusion equipment operates over the following:
• CATV 75 Ohm cable with F connectors
• Single-mode fiber (SMF) or multi-mode (MMF) cable with SC/APC fiber connec-
tors throughout the fiber network, including fiber distribution panels
These cables are widely-used, industry standards for the cable TV industry. The regu-
lations and guidelines for Fusion cable installation are identical to those specified by
the TIA/EIA 568-B standard and the TIA/EIA/570-A standards.
TE recommends solid copper center conductor, plenum-rated CATV cable and con-
nectors for conformity to building codes, standards, and to ensure stated performance
of maximum distance and RF specifications.
CommScope 2065V cable or equivalent is required for RG-59.
CommScope 2279V cable or equivalent is required for RG-6.
CommScope 2293K cable may also be used for RG-11.
NOTE: Refer to Appendix A for more information related to 75 Ohm
CATV.
TE recommends connectors with fixed centerpins to ensure proper seating and to
eliminate oxidation, which occurs with bare center conductors. Recommended con-
nectors are as follows:
CANARE Connectors
• FP-C4F for commScope 2065V cable
• FP-C55A for CommScope 2279V cable
• FP-C71A for CommScope 2293K cable
