1 Introduction

Product function

This shelf is a mechanical enclosure for a physical fiber management system.
It is used for splicing and patching: splicing primary coated fiber from loose tube cable or pigtails to fiber pigtails
on a single element base and connector patching to patchcords with a capacity of 144 (= 6 x 24) splices and
connections.
It is a high density multifunctional unit designed for particular applications and environments.
This unit uses Patching/Splicing Trays with 12 connector positions.
The GPST-12 trays house the splices, slack fiber, connectors, pigtails and patchcords.
It can be installed in Commscopes FIST rack and other 19” or metric (ETSI) racks.

Follow local safety regulations related to optical fiber plant elements.
