It only takes a few days for the faulty parts to be sent back and forth, so it is worth spending two minutes to judge whether to check first or return for repair first. EB-LINK technical support summarizes three types of typical signals in daily delimitation.

It is recommended to check these three situations by yourself first.

First, the fault occurred immediately after a certain operation: the fiber jumper was changed, the distribution frame was moved, the topology was adjusted, and the original state was restored first for verification; second, DDM showed that the optical power at the receiving end was obviously low but the transmitting end was normal. Eighty percent of the fault was due to end surface contamination, bent jumpers, or mismatched wavelengths, which can be located by cleaning and fiber replacement; third, there was occasional packet loss and there were environmental changes such as frequency conversion and thunderstorms on site. There was no need to rush to determine that the module was bad before interfering factors were eliminated.

If these signals appear, prepare for repair immediately.

After cross-verification, the fault followed the module or transceiver - the port was still not recognized, but it was restored after replacing a known normal part; the equipment had visible damage and ablation smell; or it failed to work when it was powered on for the first time after arrival. In this case, there is little point in continuing to fiddle with it on site. It is faster to keep the labels and photos and follow the warranty process to create an order.

Critical links allow two lines to run in parallel

If the trunk is interrupted, you cannot wait. You can first replenish one from the spare parts pool or spot stock, such asSFP+ 10G single-mode dual-fiber 10km optical moduleStocks are always in stock; faulty parts are registered for repair at the same time, so the two lines run in parallel without conflict.

If you are not sure which category it belongs to, send the phenomenon, time point and operations performed to technical support for remote judgment. Communication by phone at 0755-83179002 during working days is more efficient.
