Maintain Transceivers and Optical Cables
To maintain high signal accuracy and to prevent damage to the connectors, transceivers and fiber-optic cables
must be kept clean and free of dust. Attenuation (loss of light) is increased by contamination 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 than it is necessary. Repeated removals and insertions can
• Keep all optical connections covered when not in use. Clean them before use to prevent dust from
• Do not touch the ends of connectors. Touching the ends would leave fingerprints and cause other
• Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In
• Inspect routinely for dust and damage. Clean and then inspect fiber ends under a microscope to determine
