Cleaning Dirty Fiber Optic Ports and Connectors

Fiber optic transceivers are sensitive optical devices. Handle them carefully. If dirt collects on a fiber optic lens, the associated LED may not light. You may also notice degradation in port performance, indicated by an increase in the Link Error Rate (LER) count on a port.

To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at all times when they are not in use.

WARNING: Follow all safety precautions in Chapter 3 when working with fiber optic components.

To clean a fiber optic lens, take these steps:

1Remove any accumulated dust or debris from the port or connector by blowing across all surfaces with a canned air duster.

Compressed gas is recommended, such as Chemtronics’ Ultrajet or the Triangle Tool Group’s Liqui-Tool Dust-A-Way. Do not use commercial compressed air or “house air” because of the risk of oil contamination.

2Reconnect the cable to the port to check whether dusting has corrected the problem.

3Gently wipe the ports with a lint-free, nonabrasive, nonadhesive swab. Microswabs by Texwipe are recommended.

4Gently wipe the connectors with a lint-free, nonabrasive wipe or pad. Texwipe pads are recommended.

Avoid touching any surface after you clean the connectors.
