NOTE
Optical fiber connectors used with this equipment have high
precision optical surfaces which mate two optical fibers
accurately. It is good practice to periodically clean the ceramic
ferrule (ends of optical fiber jumper cable) with reagent grade
alcohol on an optical grade lintless tissue. Dry connector end
with a dry (optical grade) lintless tissue. Connector should be
carefully handled to avoid contamination or damage when
unprotected by its dust cap. Replace connector dust cap when
optical fiber jumper cable is not connected to equipment. Small
amounts of dirt, dust, oil or other foreign matter on connector
ferrules can cause abnormal attenuation or damage to the
connector. Do not touch connector ferrule with unwashed
hands as this deposits oil which acts as a sticky surface to
attract dust, etc.
NOTE
Both FC-PC and ST connectors are keyed. Key on connector
must be aligned with key slot on connector receptacle.
