New catalogue for GJS03 series fiber optic splice closures

Dear customers,

Our new catalogue for high-quality splice closures of series GJS03 is already available. Inside you can find detailed information, pictures and all parameters you need.

The GJS03 series is high-quality fiber optic splice closures which are specially designed to ensure high protection and full recovering of physical construction and functionality of connected optical cables. The dome material is mixed with chemical agents in order to increase the resistant of corrosion and aging and also to provide longtime UV-protection.
It can be installed in aerial locations, ducted applications, direct buried, manholes. Small volume and large capacity.

Catalogue FOSC GJS03 A4, B4, A8, B8, M4AX, M5AX


Main Features

  • Excessive fibers can be stored in storage baskets. Easy in fiber management.
  • Fabricated by mixing the imported material and other chemical assistant agent (ageing resistance & ultraviolet radiation resistance), increase of service life
  • Base-to-dome seals on closure are mechanical and heat-shrinkable for ease of installation and reentry. No other sealing adhesive tape is needed
  • Base and dome sealed with clamp and O-ring system
  • The splice trays are hinged for access to any splice without disturbing others trays
  • The inner parts and fixing parts are made of stainless steel
  • Closure with a earthling device protect it from damage by lightning
  • Compatible with most cable types (single fiber or ribbon), and cable constructions (loose tube, central core, slotted core, modular). And the product can be used in any environment (aerial, buried, hand-hole, manhole) and in many applications (tap-off, expressed, branch, and repair)
