4x2 Reverse Configuration Module with Auxiliary Reverse RF Injection
(8-Port OIB)
(8-Port OIB)
Signals from the left side of the amplifier (Ports 1 and 2/3) are combined and routed
to a transmitter (XMTR 1). Signals from the right side of the amplifier (Ports 4 and
5/6) are combined and routed to a different reverse transmitter (XMTR 3). An RF
signal from an external source can optionally be injected and coupled with the
reverse RF inputs from Ports 3/6 and routed to Transmitter 1.
Note: This module can only be used with an 8-port optical interface board. (There is
no transmitter 3 position with a 6-port optical interface board.)
Install the transmitter that is dedicated to Ports 1 and 2/3 in XMTR 1.
Install the transmitter that is dedicated to Ports 4 and 5/6 in XMTR 3.
