Optical Cable Line Fault Resolution

The steps and measures for handling fiber optic cable line failures are as follows:

Fault diagnosis and location. Utilize professional tools such as optical power meters and optical time-domain reflectometers (OTDR) to inspect fiber optics to determine the fault location.

Fault repair points have been addressed. According to the specific nature of the fault, corresponding repair measures have been taken. If the optical fiber at the optical fiber joint in the cable joint box is broken, a new joint can be made or a reserved one can be pulled, utilizing the original joint; if some bundles in the cable are broken or some fibers in a single bundle are damaged, the "sky window" splicing method can be used for fault fiber repair; if the optical fiber at the connector's tail fiber joint is broken, a new joint can be made, and if the flexible joint is broken, a new optical fiber connector needs to be replaced.

Post-rectification testing. After the repair, the entire attenuation of the fiber optic channel was measured using an attenuation tester, and the data was recorded for archiving.

Preventive Measures: During the repair process, ensure the purity and integrity of the fiber optic cable are maintained to prevent further damage. Regularly inspect the connection points and the surface of the fiber optic for any damage or dirt, and take appropriate actions for repair or cleaning to ensure the normal operation of the fiber optic cable.

Ensure maintenance and cleaning. Prior to any fault repair, thoroughly clean the fiber optic cable. Use professional fiber optic cleaning tools and cleaning solutions, avoiding cleaners containing alcohol or other corrosive substances.

In addition, when dealing with optical cable line failures, it is also necessary to consider the physical environmental conditions of the cable itself, such as the impact of temperature and humidity.
