Optical Interface Board (OIB)

Optical Interface Board Description
The Optical Interface Board (OIB) provides all interconnections between the
modules in the housing lid of the 1.2 GHz SHO GS7000 Node. The modules in the
housing lid include the optical receiver, optical transmitter, power supply,
Remote-PHY module, and status monitoring/local control modules. Each module in
the lid plugs directly into the OIB through a connector header, connector header and
RF connectors (in the case of the Remote-PHY module, or row of sockets. Input
attenuator pads are provided on the OIB (in the housing lid) for the optical receiver
module and the Remote-PHY module. 1 or 2 output attenuator pads are provided on
the OIB for each optical transmitter and/or Remote-PHY module in the housing lid.
All RF and power cables running between the housing lid and base also plug into
the OIB.
The OIB can be field replaceable. All optical modules, power supplies, RF cables,
power cables, and OIB mounting screws must be removed in order to remove the
OIB from the housing lid.
