Existing network must be optimized, dispose fiber cable network on a large scale.
Along with the increase of optical cable sheath kilometer, network operation difficulty is increasing.And attendant is fewer and feweri, optical cable
Machine room the most all unmanneds.Go out Cable's Fault, it is impossible to find in time, judge, position.
Traditional Cable's Fault analyzes method, usually utilizes OTDR (Optical Time Domain
Reflectometer, optical time domain reflectometer) record trouble point distance, draw fault points of optical cables with reference to contrast optical cable physical length
Length, select corresponding cable connection point as geographical reference point to delimit fault zone, then by tissue work on the spot people
Member, along this region detection lightguide cable link, finally determines Cable's Fault position.But, above-mentioned employing OTDR carries out Cable's Fault and divides
The method of analysis, there are the following problems:
The when of the generation of 1, Cable's Fault, it is impossible to find immediately;I.e. enabling and be found that, personnel may not be at communications equipment room
On duty, need to rush towards machine room;
2, need to be carried to precision instrument OTDR scene, and execute-in-place need ODF is plugged tail optical fiber, pull out wrong and
Insert bad port risk;
3, increase when the loss of optical cable indivedual fibre core or interrupt finding in time;And an OTDR can only test, monitor one
Root optical fiber, utilization rate is low;
4, the when of manually judging Cable's Fault distance with OTDR, the restriction of personnel's technology, proficiency level is received;
5, the Cable's Fault distance tested out cannot be immediately passed to judgement, alignment system;
6, i.e. enable navigates to particular location, and the impact of site environment does not has the mark of map geographic position, prompting.
7, due to optical cable mark affiliated facility, to gather information complete, or position inaccuracy and map and optical cable mark attached
Facility locations can not upgrade in time, and causing trouble range accuracy is inadequate.
Summary of the invention
