ABSTRACT:
The present invention is a high-speed and low-cost optical communication network. A preferred embodiment of this optical communication network comprises an accommodation device, optical couplers that are connected to corresponding ports of this accommodation device, and communication terminals that are connected to corresponding optical couplers. Further, data transmitted by the communication terminals to the accommodation device is code-division multiplexed. Because data collision is prevented by means of code division multiplexing, control of the timing with which the communication terminals transmit data is not required. Meanwhile, data transmitted by the accommodation device to the communication terminals is time-division multiplexed because there is no risk of collision.
