ITEM 9000-0009 – 12-PORT MULTIMODE FIBER OPTIC TERMINATION PANEL

ITEM 9000-1207 – 96-PORT SINGLEMODE FIBER OPTIC TERMINATION PANEL

DESCRIPTION

This work is furnishing, installing, terminating, mounting, and testing fiber optic cables, fiber optic cable termination panels, fiber optic lateral/drop cables and fiber optic backbone cables from outside plant fiber optic cable to factory manufactured connectors in a cabinet that provides front access to terminated fibers.

MATERIAL

Provide fiber optic termination panel (FTP) that meets or exceeds the following specifications:

· Number of terminations as indicated

· Uses LC connectors

· Access: Front and rear, fold-down or swing out

· Cabinet Painted Metal Construction

Provide panel with space and a mechanism for storing fiber splices and slack for both used and unused fibers within the panel.

Provide FTP’s as rack-mountable to EIA 19-inch equipment racks.

Provide fiber pigtails (single mode or multi-mode respectively) that meet the optical characteristics of the drop cable used, including mode diameter.

CONSTRUCTION

Install panels so connectors are accessible to a technician standing in front of the cabinet with the front door open. Install panels to accommodate fiber optic patch cables between any two connectors without reaching the patch cables’ minimum bending radius.

On the panel optically connect each connector to a fiber in the 12-strand fiber drop cable; connection to not cause in excess of 0.3 dB optical signal loss when tested at 1310nm.

Terminate with connectors all fibers entering the cabinet on the rear of the connector panel. Provide and install jumpers of sufficient length to connect the front side of the connector panel to the fiber equipment contained within the cabinet as specified herein.
