Maintaining Transceivers and Optical Cables
Transceivers and fiber-optic cables must be kept clean and dust free to maintain high signal accuracy and
prevent damage to the connectors. Contamination increases attenuation (loss of light) and should be below
0.35 dB.
Consider the following maintenance guidelines:
• Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is
• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions
• Keep all optical connections covered when not in use. Clean them before using to prevent dust from
• Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other
