Abstract
The present invention provides an optical switching apparatus and method of an eNB. The above apparatus includes: a fiber transceiver module (), configured to receive an optical signal which carries transmission address information from the source input end () and transmit the optical signal; a transmission address module (), configured to receive the above optical signal, query routing, and manage and maintain transmission address(s); a switching control module (), configured to obtain the transmission address information of the optical signal, analyze and select an optical switching mode, and transmit a routing control signal which carries the transmission address information and the optical switching mode; and an optical switching and routing module (), configured to receive the above optical signal and transmit the same to a destination output end () by the fiber transceiver module (), receive the routing control signal of the switching control module (), select a routing and transmit the optical signal to the destination output end (). According to the present invention, the RRU and the BBU of the eNB can communicate with devices of the BBU and the RRU of the different manufacturers, can be applied to the multi-mode base station, and can adapt to the different mode; therefore the transmission distance is enlarged.
