Baseband unit (BBU)-radio remote unit (RRU) failure judgment method for telecom base station

The invention discloses a baseband unit (BBU)-radio remote unit (RRU) failure judgment method for a telecom base station. The method is characterized in that: a BBU monitor is arranged at a BBU; each RRU is correspondingly provided with an RRU monitor, is connected with a corresponding RRU monitor by optical fibers, and is also connected with the BBU through the output of the corresponding RRU monitor by a pair of fiber interfaces; the BBU monitor transmits information to a network in a wired or wireless way; the signals transmitted by the network are received by a receiving terminal and displayed on a monitoring management software platform to realize the real-time monitoring and failure alarming of the BBU-RRU. The method is adaptable to a modern optical transmission network; and by the method, the real-time monitoring of the BBU-RRU is realized, and the most common failure judgment of the BBU-RRU is realized.
