1 Introduction
The FOSC-450 is an environmentally sealed enclosure for the fiber management system that provides the function
of splicing in the external network.
The FOSC-450 has provision for all cable terminations and sealing requirements.
The closure is a single ended design made of a thermoplastic material. The base and dome are sealed with
a clamp and O-ring system. For cable sealing , a wrap-around block with 6 ports is used that contains a pre-
installed gel profile. One can terminate 6 cables, with a diameter of minimum 9 mm and maximum 25 mm.
It can be opened and closed repeatedly without replacing or changing components.
