Maintenance of fiber optic lines Metro is what

Routine patrol

Municipal building of the road repair, road expansion, and other excavation works has increased every year, intensified, large machinery broke telecommunications pipelineconstruction, injury, damage, resulting in blocking the communication cable line disruptionsoccur frequently. Strengthen the telecommunications pipeline is to reduce or avoid routine patroldamage due to external force effective means of fiber-optic cables.

Regular irregular fiber test equipment

Core cable spare time to time the test is to find a regular cable core implied an important means of blocking obstacles. Most of the core metro fiber-optic cables the larger section of the current monitoring systems are not able to monitor each core is, a fiber optic cable can onlymonitor one of the few core, non-blocking core occupied in most cases, not only through regularregular fiber test equipment to find.

Emergency repair

Line break in the cable barrier repair process, the fiber optic cable and transmission line maintenance departments should closely coordinate equipment maintenance department, andsubject to transmission maintenance scheduling department. Under normal circumstances, the light system alarm, first determine whether the transport sector issues for fiber-optic lines, cablelines is then immediately notify the maintenance department, maintenance personnel through the core tests to further determine the type of cable fault lines, scope, location, the conditionalcase, as soon as possible to meet the transport sector temporary interruption of the light systemjumpered other spare core for communications recovery.
