6.1 Cleaning Fiber Optic Connectors
DANGER: The fiber cable carries invisible laser radiation. AVOID
EXPOSURE TO THE BEAM. Never operate a unit that has a
broken fiber or a disconnected fiber connector.
Dirty optical connectors are the leading source of poor performance in a
broadband optical fiber network. Dirty optical connectors lead to optical
signal loss and reflections, which in turn can seriously degrade signal-to-noise
(SNR) performance and, in some cases, distortion performance.
Harmonic recommends that you clean all mating fiber connectors, before
connecting them to an optical amplifier.
In addition, if you suspect that the optical connector of an HOA 7100 may
have been exposed to contamination (by a dirty fiber cable connector, for
example), you should properly clean the HOA 7100 optical connector before
connecting the optical fiber.
