1.0 General Product Description
The FOSC 450 fiber optic splice closures use compressed-gel cable
seals to environmentally seal fiber cable splice points.
The maximum single splice capacity of the FOSC 450 B6 closure is
144 with 24 splices stored on six trays. The maximum mass fusion
splice capacity is 288, only four trays are needed.
A larger FOSC 450 D6 closure is also available. Splice capacities for
the D size are 576 for single splicing and 1152 for mass splicing.
Note: Cable blocking is not recommended in this closure due
to the space constraints. If cable blocking is used, follow the
special instructions in "D/Gel Cable Block" installation instruc-
tions.
