Home / Dual-wavelength optical cable fault
Poor cable management can put strain on a connector that causes misalignment, or the connector may not be properly seated and connected with its mate. Worn or damaged latching mechanisms on connectors or adapters are sometimes the culprit. This document presents a troubleshooting guide for fiber optic cables once deployed and in regular use. Symptom: wavelength-dependent loss (often worse at longer wavelengths), loss that spikes when a cable is flexed or moved, or visible tight loops and kinks at routing points. The Optical Time-Domain Reflectometer (OTDR) is a fiber fault diagnostic tool recommended by standards such as the International Telecommunication Union and the International Electrotechnical Commission. Therefore, being able to identify and fix these issues is paramount in ensuring the longevity and efficiency of the network.
