A fiber optic cable interruption exposes all weak links simultaneously. Whether the plan can be used depends on whether it answers three things: who to call under what circumstances, which fiber core to pour on, and how many minutes each step is stuck to be completed.

Classified by business impact, how many cores will be broken if not pressed?

It is recommended to classify the situation into three levels: those that affect monitoring backhaul or voice dispatching are classified as level one, and two people must be present and the backup route is activated immediately; those that only affect access to a single building are classified as level two, and the attendant must handle them according to established actions before reporting; those that only involve spare fiber cores are classified as level three, and will be scheduled for planned maintenance after registration. At each level, the response time limit, approver, and external notification standards are clearly written to prevent the emergency repair site from waiting for instructions, and to prevent the team from being afraid to take action for fear of taking responsibility.

Check the routing map and available fiber cores in advance

• Mark the physical direction of each trunk, the location of the connector box and the length of the reserved disk. The drawing must be able to match the on-site markings.
• Record the spare core number and do a light test every quarter to prevent the fiber core itself from deteriorating after being idle for a long time.
• Check whether the module gears of the switchable path match. Long-distance modules connected to short fiber jumpers are prone to excessive light collection.
• Specify which sections belong to the external pipeline unit, and put the fault reporting telephone number and the repair time limit stipulated in the contract on the same page.

Arrange the emergency repair time by hour, don't just write as soon as possible

Available writing methods are: 0 to 0.5 hours to complete alarm acknowledgment and port-level isolation; 0.5 to 1.5 hours to use OTDR to identify obstacle points and decide whether to switch to spare fiber cores; 1.5 to 3 hours to complete fiber patching scheduling on the patch panel side to allow business recovery first; and put splicing and permanent repair in the change window the next day. After switching to the spare fiber core, the light receiving margin must be re-tested. Only when the power reaches the standard can the closed loop be confirmed. It is a common mistake to shut down the fiber only when the link light is on. likeOptical fiber project for vehicle monitoring system in highway tunnel in a provinceIn this kind of scenario where there are many points and long lines, the plan should also indicate the location of the nearby points where spare parts and jumpers are stored. When EB-LINK assists in sorting out such lists, it usually checks them station by station according to the models in use.
