Fiber Optic Cable Connector
The transmitter and receiver units of the
FOX 2G Tx/Rx AV are connected by an LC duplex
SFP connector. Fiber optic link 1 connects the Tx port
of the transmitter and the Rx port of the receiver. It
carries video, audio and/or data output from the
transmitter to the receiver.
Fiber optic link 2 connects the Tx port of the receiver
with the Rx port of the transmitter. It only carries the
responses to RS-232 commands and is not required for
transmitting video and audio signals.
However, if link 2 is not enabled, the ability to
congure the system through SIS commands is limited
by the lack of communication from the receiver to
the transmitter. All commands issued through the
transmitter are valid but responses to status queries
may return invalid data.
Signals may be transmitted 500 m (1,640 feet) over multi-mode
(MM) ber and 30 km (18 miles) over single mode ber. An MM
transmitter must always be connected to a MM receiver and an
SM transmitter can only be connected to a SM receiver.

The FOX 2G Tx/Rx AV outputs continuous
invisible light (Class 1 rated), which may be
harmful and dangerous to the eyes; use with
caution.
Do not look into the rear panel fiber optic cable
connectors or into the fiber optic cables themselves.
Plug the attached dust caps into the optical
transceivers when the fiber optic cable is unplugged.
An LED above each port lights when a signal is received. The
receiver unit's optical Rx port will light when a signal from ber
link 1 reaches the receiver. The transmitter unit's optical Rx port
will light when a signal from link 2 reaches the transmitter.
