PPN CABINET TO EPN CABINET

MAXIMUM CABLING DISTANCES

The maximum length of the fiber-optic cable between the PPN

cabinet and the EPN cabinet is approximately 7.6 km (25,000 feet)

depending on installation requirements. The requirements that

determine the maximum fiber link distance for an installation are:

●

The mean loss and the length of the outside plant fiber

cable

The mean loss and the length of fiber cable shipped with

the cabinet (including any fiber riser cable)

The mean loss of a lightguide cable connector ST® and

the number of ST connections

The mean loss of a rotary mechanical splice and the

number of splices

Higher order mode loss

The Premises Service Consultant (PSC) must always be con-

sulted in the fiber link design for any remote EPN configura-

tion.

The speed of the fiber optic cable link between the PPN cabinet and

the EPN cabinet is 32.788 Mb per second.
