Cleaning Patch Cord Or Pigtail Fiber Optical Connectors; Troubleshooting - Baudcom BD-5800H Operating Manual

6.1.1 Cleaning Patch Cord or Pigtail Fiber Optical Connectors

To clean optical connectors, we recommend using a fiber optic connector cleaning
cartridge (such as NTT Cletop). If a cleaning cartridge is not available, follow these
steps.
To clean the optical connector of a patch cord or pigtail:
1. Fold a piece of unused dry lens cleaning paper twice, for a four-ply thickness.
2. Use a drop of high-grade isopropyl alcohol to wet part of the paper.
3. Lay the connector on the lens cleaning paper with the tip touching the paper.
4. In one continuous motion, pull the connector from the wet part of the paper to the
dry part.
