Scenario analysis - cable identification and search testing requirements
With the increasing demand for optical cables, the number of cores has expanded from single-core to a maximum of 2096 cores. However, the more optical cables are buried, the more complex the laying routes become, leading to greater problems. With the rapid development of communications and the integration of new forces such as power and broadcasting, the merger of operators has resulted in a large number of optical cables requiring maintenance. Optical cable pipelines face various potential threats. Laying multiple optical cables in the same pipeline, messy pigtails in optical distribution frames, and missing labels all increase the difficulty of optical cable line maintenance. How to efficiently troubleshoot optical cable line faults and quickly obtain optical cable pigtail resource information has become a key point of user needs.
Optical cable census function
The optical cable identifier is specially tailored for telecom engineers or technicians. It converts the knocking vibration signals of optical cables into visual and audio signals through optical coherent demodulation, enabling accurate location and identification of target optical cables laid in environments such as manholes, tunnels, pipelines, and overhead poles.
Engineers only need to tap the optical cable gently to easily identify the The optical cable identifier is specially tailored for telecom engineers or technicians. It converts the knocking vibration signals of optical cables into visual and audio signals through optical coherent demodulation, enabling accurate location and identification of target optical cables laid in environments such as manholes, tunnels, pipelines, and overhead poles. target optical cable they need to find.
Identification of cables comparison method
In front of these messy fibers, if not with our surveyor, the common construction Fiber optic on-site scenario :The intricate cables make it difficult for the installation and maintenance workers to accurately locate the faulty optical cable. method for construction personnel is:
1）Start from the known place and pull one by one;
2）Use OTDR with bending optical cable, use OTDR with quick-freezing liquid.
Manual stretching method
The workers traced along the known damaged location of a particular optical cable to find the optical cable to be identified.
Disadvantages: It takes a lot of time to find, wastes manpower; the binding place can not be separated, and there are many difficulties.
Use OTDR
The curve obtained by OTDR test of bent optical cable, the ladder type in the figure is the loss step caused by the bending of the optical cable.
Disadvantages:
1) Using OTDR plus bending the optical cable(for damage to the optical cable); Using OTDR with cryogenic fluid (Operating difficulty is high, potential toxicity);
2) Cables insensitive to bending, such as G.657, cannot be identified by either method.
Fiber Optic Inventory
When multiple optical cables in the same pipeline are cut at the same time (or during a splice), it can easily each optical cable to avoid fault repair delays (or splice errors) caused by missing optical cable information; at the same time, it can identify optical cables across cable segments.
Fiber optic on-site scenario
The intricate cables make it difficult for the installation and maintenance workers to accurately locate the faulty optical cable.
The maintenance and management of a large number of optical cables has become a difficult problem. In particular, when optical cable faults are caused by aging, natural damage, man-made damage, it will seriously interfere with the effective operation of the information society and affect information security. Therefore, it is extremely important to quickly detect the location of the optical and carry out emergency repair and recovery in the shortest possible time.
