Installation Instructions
Dual redundant fiber units have a Secondary fiber
port. (see Back Panel figure) Dual redundant sys-
tems are available as single fiber systems (2 fiber
connections) or dual fiber systems (4 fiber connec-
tions).
For Single fiber Dual redundant systems:
Connect the TX of the transmitter to the RX of the
receiver and connect the TX of the receiver to the
RX of the transmitter. There will be only a Primary
Opto connector.
For Dual fiber Dual redundant systems:
Connect the TX of the transmitter to the RX of the
receiver. The will be both a Primary and a Secon-
dary Opto connector. Note, do not cross the Pri-
mary fiber connections with the Secondary fiber
connections. There will be a two fiber connection to
the Primary fiber ports and a two fiber connection
to the Secondary fiber ports.
Addendum to cover
Dual Redundancy Fiber Option
The dual redundancy option provides a secondary path to prevent communication losses in the event
of a fiber failure.
For reliable dual redundancy a secondary fiber path should be routed separately from the primary path.
In the event of a cable break, all video, data/audio and Ethernet channels are redirected and transmit-
ted over the secondary path.
