    Hi all,

    Im working with Huawei BTS 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?
