SECTION 6
Installing Unison Components
6.1 Installation Requirements
6.1.1 Component Location Requirements
Unison components are intended to be installed in indoor locations only.
6.1.2 Cable and Connector Requirements
The Unison equipment operates over standard Category 5 or 6 (Cat-5/6) screened
twisted pair (ScTP) and industry-standard single-mode fiber (SMF) or multimode
fiber (MMF) cable.
These cables are widely used industry standards for Local Area Networks (LANs).
The regulations and guidelines for Unison cable installation are identical to those
specified by the TIA/EIA 568-A standard and the TIA/EIA/IS-729 supplement for
LANs (see Appendix B).
LGC Wireless recommends plenum-rated Cat-5/6 ScTP and fiber cable and connec-
tors for conformity to building codes and standards. ScTP is required in order
to meet FCC and CE Mark emissions tests.
6.1.3 Neutral Host System Requirements
As in any Unison system, a neutral host system requires one pair of fiber strands
between each Main Hub and each Expansion Hub, and one Cat-5/6 cable between
each Expansion Hub and each RAU. To help achieve the cost savings possible in a
neutral host system, it is advantageous to install additional cables for future growth.
