B. Fiber Optic Patch Panels
Each fiber optic backbone shall be terminated in a twelve port or two six port
fiber optic patch panels mounted on pre-threaded 19 inch panels. The
Contractor shall terminate all strands of the fiber optic backbones using
connectors
as
specified
in
General
Material
Standards,
paragraph 7B. Connectors shall be mounted in the breakout boxes or on
