This shelf can be used on both the CO-side (CFJ) and Station-side (OEI) of a hybrid-fiber HVI scheme. The shelf is fabricated from stainless steel and is designed in such a way as to act as a virtual Faraday Cage enabling extremely high noise immunity. For outdoor use, shelves can be housed in closures which meet the NEMA-4X requirements for telecom plant equipment. (These closures may be ordered separately). Each shelf has one slot for a plug-in power supply and six slots for optical service modules. Any slot can be used for an optical service module or a plug-in power supply.
When installed outdoors, the shelf is housed in a weather-resistant closure which can be wall-mounted, pole-mounted, or installed in a pedestal. When installed indoors, the shelf is mounted on a painted, treated plywood backboard, optionally mounted in a 19” or 23” rack or inside a non-metalic cabinet that is H-Frame or wall-mounted.
Fabricated from high-quality stainless steel, the shelf's backplane motherboard has seven edge connectors; one for each slot. Each connector distributes input power to the optical modules and gives access to contact-closure alarm connections.
The break out box kit (7250BB-50) includes an array of twelve RJ connectors and cabling that terminates in an Amphenol connector for quick attachment to a 66-tyype punch block. The TeleLite Access Card is a passive device and gives you access to the traces on the backplane of the shelf. The TeleLite Access Card, Model #720001 is used to input a locally available -48Vdc to the backplane motherboard and provides access to alarm contact points for optical service modules located in the CFJ (CO-side) and OEI (Station-side). These items are sold seperately.
