The Multinet4 requires several different types of connectors, cables, and wires.
Requirements and recommendations are listed below:
The fiber cables connected to the Multinet4 must be:
• non-dispersion shifted, single mode (SM)
or
• multi-mode (MM) fiber cables defined by the Telcordia Technologies
General Recommendation 20-CORE standard
and
• terminated with LC, ST, and SC connectors
The primary ground stud located on the rear of the chassis must be used to
connect to an approved ground with a wire meeting the following criteria:
• 14 AWG (minimum)
• a maximum of five feet in length
• terminated on the ground lug side with a #10 ring lug
The facility power cabling attached to the Multinet4 chassis must meet the
following criteria:
• cabling constructed using 14 AWG stranded wire
• cable firmly attached to the terminal holes of the non-polarized
power unit, as illustrated in FIGURE 2–11:: Non-Polarized Power Input.
• cable routed and strain relieved to the chassis according to good
wiring practices
Copper I/O cables and connectors must be shielded.
It is mandatory that an accessible disconnect is provided in the Installation wiring
Before installing the Multinet4 you should be aware that devices that employ laser
technology, such as the fiber optical LC ports and associated cabling, can be dangerous.
Do not look directly into a fiber optic port or into the end of a fiber optic line. Doing so
could cause injury to your eye or blindness. Always assume that there is laser activity in the
line or port, even if the device is powered down. As a reminder, whenever this manual calls
for the handling of fiber optic lines, those instructions will be accompanied by a "Laser
Warning," as follows:
DO NOT LOOK INTO A FIBER OPTIC CABLE OR PORT! These can produce invisible light that
may do serious eye damage. Always assume that fiber optic cables or ports are actively
radiating light energy.
