Optical Fiber
The VERSITRON
VersiVision
FVTM880x and FVRM880x
video transmission systems
series is available for most applications using multi-mode or single-mode optical fibers.
Please be certain that the correct size and type of the fiber is being used for the particular
transmitter/receiver combination.
Also be certain that the attenuation and bandwidth of the fiber optic cable being used is
within the range of the system’s loss budget specifications.
General
Any dirt or dust may easily pollute or block the fiber from accepting or radiating light.
Therefore, please try to keep the optical connector clear and always use the dust caps
whenever the connector is exposed to air. It is suggested that the tip of the optical connecter
should be carefully cleaned with a lint-free cloth moistened with alcohol from time to time.
The status of any of the VIDEO LED should provide the first clue as to the origin of any
operational failure. If the VIDEO LED on the receiver unit is off, it usually means that the
fiber is broken or has too much attenuation.
Please also make sure that the transmitter and the receiver are not used in opposite positions.
If the system is still not working after examining the above possibilities, please contact our
Customer Service Department for further assistance
Data Link
Even when installed exactly as directed, it is possible that the data/audio function may fail to
operate properly. If this problem occurs, first please check the data cable connection to the
camera(s), and then check whether the data cable connector is firmly connected to the unit.
If the system is still not working after examining the above possibilities, please contact our
