The invention discloses a communication method, communication equipment and an optical fiber matrix system. The communication method can be used for the optical fiber matrix system. The optical fiber matrix system comprises a switching device and a signal transmitting and receiving device. The communication method comprises the following steps of detecting whether the optical fiber matrix system has an available timing sequence; and realizing communication between the switching device and the signal transmitting and receiving device through the available timing sequence. Through detecting the available timing sequence in the optical fiber matrix system and realizing communication between the switching device and the signal transmitting and receiving device through the timing sequence, the optical fiber matrix can be guaranteed to have the available timing sequence in a process of communication with the optical signal transmitting and receiving device always, so that a problem that the optical fiber matrix cannot communicate with any equipment connected to a lower end in the absence of video transmission can be solved.
