1.1 Installation Instruction description
The installation instruction describes the necessary steps to install the FOSC-650C.
The installation instruction illustrates the use on loose tube cables. If other cable types 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-650C in-line closure is a gel-sealed fiber optic splice closure. The closure has
maximum splicing capacity of 384F for single splice and 864F for mass fusion splice (Ribbon 12)
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 8 cable ports, 4 on each side.
