NOTES: The FOX AV consists of a transmitter (FOX Tx AV) and a receiver (FOX Rx AV) with one or two fiber optic
cables linking the two units.
The analog video input signal is digitized pixel for pixel in the transmitter, sent digitally through the fiber
cable, and converted back to analog video in the receiver.
The analog audio signal(s) is (are) digitized in the transmitter, sent through the fiber cable, and converted
back to analog audio in the receiver.
These transceivers are class 1 laser products. They meet the safety regulations of IEC-60825,
FDA 21 CFR 1040.10, and FDA 21 CFR 1040.11.
Optical ber interconnection between transmitter and receiver
Number/type .................................. 1 or 2 fiber optic
NOTE: Only one fiber is required to transmit video, audio, and unidirectional data. A second fiber is required to
transmit return data for bidirectional control/communication.
Connectors .................................... 2 LC connectors
Operating distance
Singlemode ............................. 30 km (18.75 miles) with singlemode (SM) cables with a FOX AV SM
Multimode ............................... 500 m (1640') with 62.5 µm multimode (MM) cables with a FOX AV MM
1 km (3280') with 50 µm multimode cables with a FOX AV MM
2 km (6561') with 50 µm, 2000 MHz bandwidth laser optimized multimode cables
with a FOX AV MM
NOTE: Operating distance is approximate. These are typical maximum distances that may vary depending on
factors such as fiber type, fiber bandwidth, connector splicing, losses, modal or chromatic dispersion,
environmental factors, and kinks.
