CAUTION:
If the cable does not install easily, ensure that it is correctly oriented before
continuing.
Maintaining SFP Transceivers and Fiber-Optic Cables
SFP transceivers and fiber optic cables must be kept clean and dust-free to
maintain high signal accuracy and prevent damage to the connectors. Attenuation
(loss of light) is increased by contamination. Therefore, attenuation should be kept
below 0.35 dB.
Follow these maintenance guidelines:
v
SFP transceivers are static-sensitive. To prevent ESD damage, wear an
ESD-preventive wrist strap that is connected to the chassis.
v
Do not remove and reinsert a transceiver more often than necessary. Repeated
removals and insertions can shorten its useful life.
v
Keep all optical connections covered when not in use. If they become dusty,
clean before using in order to prevent dust from scratching the fiber-optic cable
ends.
v
Do not touch the ends of connectors. This prevents fingerprints and other
contamination of the connectors.
v
Inspect cables before installation, for dust and damage. If damage is suspected,
clean the ends and check for excessive light loss with a light meter.
