2. The optical fiber patch cord is too long:
Because the patch cord of the additional fiber is too long, redundant fibers (at least a few meters, as many as several tens of meters) are randomly stacked in the cable trough, occupying a large amount of cable space (the optical fiber occupies about). More than half of the space.
4. Insufficient space for wiring trough:
Due to the excessive redundancy of fiber optic cables, the maximum volume caused is insufficient space for cabling or even accumulation, and there is no space for additional fiber patch cord. If it is not rectified in time, it will be difficult to return, and it will no longer cost more It may not be able to solve the problem at twice the cost, and it can only be replaced with a new one.
Fiber termination quality is based on fiber cutting. No matter patch cord polishing in factory or fusion splice on site, both need to inspect the fiber endface. Mechanical tech is not reliable just because cannot inspect fiber endface, guarantee the performance temporarily with matching glue, with the time goes and environment changes, the performance changes. Fiber endface melter tech perfect the fiber endface cutting and inspect, guarantee the performance.
