Optical Cable Line Protection Measures
Optical cable lines lightning protection and strong current protection are achieved by avoiding, guiding or discharging them underground to prevent lightning and strong current from causing damage to the optical cable lines themselves, communication equipment and personnel. Optical line protection is 1+1 protection, which can be classified into 1+1 OTS trail protection and 1+1 OMS trail protection. The conduit can be made of various materials such as PVC, HDPE, or steel. The conduit provides protection against physical impact, moisture, and dust. They can also be used to route the cables through areas where there is a high risk of. UV Exposure: Prolonged sunlight degrades standard plastic jackets, making them brittle. Moisture & Flooding: Water ingress can damage fibers or connectors, leading to signal attenuation. Wind and Ice: Overhead installations. This Recommendation provides a procedure to protect the telecommunication lines using fibre optics against direct lightning discharges to the line itself or to the structures that the line enters.
