There are three basic steps to identifying loss events and restoring a fiber link.
- Identify the type and location of optical loss (fault(s))
- Repair the fault(s)
- Test the repaired fiber
Where to begin?
A Closer Look
A good way to start, is to eliminate “human error”. For example, if the problem is in a LAN, ask if anyone has recently disconnected, reconnected or moved network equipment, especially PC’s. Perhaps the connector was contaminated when the fiber optic cable was reconnected to the PC, or maybe it was reconnected improperly or maybe even not at all!
