Cable monitoring

Lancier’s monitoring systems offer flexible solutions for many applications and are used by e.g. Telia and Banverket for monitoring of copper cables. Stationary systems for fiber network monitoring offer continuous and valuable check of the damping of the fiber.


Fiber optic monitoring – maintained network quality
The transmission of the optical signal can be disturbed due to many reasons, increased attenuation may be caused by:




Small bending angles and squeezes, caused by improper laying techniques





Direct contact to water can provoke hydrogen diffusion and modify micro fissures, deteriorating the transmission characteristics of the fibers.


Later changes of the cable’s position


Imperfectly executed and aging splices



Whenever the transmission via an optical fiber is either interrupted or suffers a loss in quality, fault localization activities with all associated costs for staff, measuring equipment, transport and necessary infrastructure are initialized. But if fibers are monitored continuously, the following advantages will help to save time and money:




Performance changes can be detected early and adequate measures can be taken to avoid notable transmission problems in advance.



If the interruption is caused by the trans- mission equipment, this circumstance becomes obvious, as the fiber can be recognized as without fault, so repair activities can be limited to the equipment and the respective connections.
  In case of a sudden drop-out of a monitored fiber route there is no need to send staff to the end of the fiber optic cable in order to perform an OTDR measurement. The actual attenuation profile can be acquired without delay – right from the desktop at the maintenance centre, where also the cable route data are available, thus enabling an immediate fault localization.

An improved net availability can be guaranteed due to less faults and shorter MTTR (mean time to repair) so that even stringent contracts can be complied with.
 
A permanent surveillance provides the possibility to detect illegal attempts to access confident data.
