1 Introduction

The generic closure FIST-GCO is the environmentally sealed enclosure for the fiber management system that

provides the functions of splicing and passive component integration in the external network. The product can

be tailored to almost any required configuration by adding splicing and/or passive device Sub-Assemblies. The

FIST-GCO has provision for all cable termination and sealing requirements.

To clean FIST components, the use of isopropylalcohol is recommended.

The closure is a single-ended design made of a thermoplastic material.

The base and dome are sealed with a clamp and an O-ring system. One oval entry port for looped (uncut) cable

management and six or sixteen round ports for single cable entry/exit are included in the base. The cable seals

are manufactured from heat-shrinkable material. The Universal Mounting System provides the foundation for

mounting SOSAs and SASAs back to back. The two back to back sides have each a standard capacity of 

28, 42 or 58 units. Uncut loose buffer tube storage is available between the two UMS-sides (Universal Mounting

System). Storage of uncut looped ribbons or fibers from central core (or slotted core) cables is available with the

fiber storage basket. Storage of uncut looped ribbons or fibers can be done in individual FIST-trays.
