Product Introduction

The GL-J110M FOSC Closure device (2IN-8OUT) is designed to provide strong protection and management for optical fiber joints in the air, pipelines and directly buried environments. It is made of durable and anti-aging PP+GF material, capable of withstanding harsh conditions and offering an IP68 protection rating.

The main specifications include a maximum support for 288 optical fibers (12 trays), 2 entry ports (8-18mm cables) and 8 exit ports (6-16mm cables). Its reusable design, combined with mechanical and rubber ring seals, ensures easy maintenance, while the book-type joint tray protects the fibers with a safe 40mm bending radius. This kind of closure is a reliable solution to ensure the integrity of the network.

Key Features

High Protection Level

Constructed with high-quality engineering plastic (PC), offering resistance to corrosion, aging, and harsh weather conditions.

Versatile Cable Entry/Exit

Configured with 2 main inlet ports (accommodating cable diameters of 8-18mm) and 8 outlet ports (for 6-16/18mm cables), offering exceptional flexibility for various network architectures.

Reusability and Ease of Use

Features a book-style tray design that allows easy access and maintains a bending radius ≥40mm for fiber safety.

Optimal Fiber Protection

The GL-J110M FOSC Closure are book-style and turn-able, providing ample space and ensuring a safe bending radius of 40mm for the fibers. This prevents signal loss and mechanical damage to the delicate fibers.
