1.1 

Installation Instruction description 

The installation instruction describes the necessary steps to install the 

FOSC-350C

The installation instruction illustrates the use on loose tube cables. If other cable types (slotted 

core or central core) are used, supplementary installation steps have to be made. Contact the 

local agent to get the relevant accessories and instructions. 

1.2 

Product description 

The 

FOSC-350C in-line closure

 is a gel-sealed fiber optic splice closure designed for cable joint 

applications in the telecom outside plant network. The closure has maximum splicing capacity of 

192 splices and is suitable for deployment in aerial, underground or  direct buried environments. 

Sealing is achieved via built-in gel technology, resulting in extremely convenient re-entry and re-

sealing. The closure has four cable ports, two on both sides.
