Im working with Huawei DBS3900. We have a problem with power signal. This is happend when the rxlev around that site having abnormal signal all sector in between -70db when the distance from site in about 50 meter.
We have troubleshooting this problem by changing PMU at this site and the result is only sector 1 normal but another both sector still abnormal.
Huawei using this optical cable as a feeder cable. We already check antenna installation and jumper also problem still persist.
Have anyone of you interface this type of problem?
