PURPOSE: To provide an electric communication network in which complexity can be prevented from being extremely large, and a high speed bit rate can be handled. CONSTITUTION: An electric communication network such as a PON-FITL system equipped with a TDMA frame having a main station 2 and plural sub-stations 4-7 is well known. The bit rate of such network is likely to be increased by a request for improved performance and other services. A high speed bit rate PON fulfilling the request of the sub-station less complicated than the sub-station connected with a low bit rate PON is disclosed. This is achieved by forming the sub-stations of the main station by the data of the plural sub-stations, and bit interleaving those sub-frames with fiber cables. This sub-station receives only the sub-frames for the sub-stations. |
