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 GS7000 Node. The modules in the housing lid
include the optical receiver, optical transmitter, power supply, and status
monitoring/local control modules. Each module in the lid plugs directly into the
OIB through a connector header or row of sockets. Input attenuator pads are
provided on the OIB for each optical receiver in the housing lid. Output attenuator
pads are provided on the OIB for each optical transmitter in the housing lid. All RF
and power cables running between the housing lid and base also plug into the OIB.
Two Optical Interface Boards are available. The standard eight-position OIB allows
one to four optical receivers, one to four optical transmitters, a status monitor
(optional) or a local control module (optional), and one or two power supplies to be
plugged into it. The optional six-position OIB allows one to four optical receivers,
one to two optical transmitters or one cooled DFB transmitter, a 2X or 4X bdr
module (optional), a status monitor (optional) or a local control module (optional),
and one or two power supplies to be plugged into it. The six-position OIB is
primarily used in digital return applications.
The OIB is 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.
