When the re -approval time is reached, the cutting and the cutting and testers shall be operated in accordance with the previously formulated cutting scheme, and the following matters should be paid attention to during the operation:

1) Tests must use light sources and optical power measurements to test spare fibers to ensure that each fiber is good in transmission characteristics, and determines whether the fiber has fiber fiber.

2) Tester must clean the tail fiber and flange before inserting the fiber.

3) Tester should notify the cut

The personnel at the site do a good job of micro -bending test before breaking the fiber to determine the correctness of the core, especially when there is a fiber, and to carefully check the accuracy of each fiber. In addition, testers should notify the continuation personnel melted in time when the continuous quality is unqualified during the test.

4) Continuing personnel must be connected according to the chromatography formulated in the cutting scheme, and the core of the fiber is performed to prevent the phenomenon of error fiber and the phenomenon of errors. During the continuation process, you should be careful to avoid injuries with fiber. Once you are injured with fiber, you should fuse and recover as soon as possible, or adjust the circuit as soon as possible.

5) Tester shall synchronize the system to fiber and the system scheduling. If the system cannot be recovered quickly after the fiber is adjusted, it is necessary to restore the fiber to the original position, and then determine the cause of the fault. The confirmation of the rack light, the CD alarm light and the network management center can be confirmed by the network management center.

6) Tests should record the decaying value before and after each fiber cut, and the dying value of each joint position, including the two test values of light source, optical power meter, and OTDR. The length of the fiber must also be recorded in detail.

7) The second time the fiber should be adjusted after all the cut -off air fiber is continued, and the continuity is good, the phenomenon of the wrong fiber, and the wrong tube phenomenon, and the continuing point has been put in the fiber fiber box in the plate fiber box. Later.

8) Tests should record the restoration time of each break in detail.
