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, pre installed Gel-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 the need to replace the gel.
