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:

• SFP transceivers are static-sensitive. To prevent ESD damage, wear an ESD-preventive wrist strap that is connected to the chassis.
• Do not remove and reinsert a transceiver more often than necessary. Repeated removals and insertions can shorten its useful life.
• 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.
• Do not touch the ends of connectors. This prevents fingerprints and other contamination of the connectors.
• 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.
