Optical transmission system

摘要

The transmission system includes a main station (MS) and a plurality of substations (SS1, .., SS16) which are each coupled to that main station via a respective individual link (l1/l16) and a common link (lc) and wherein first and second information packets are transmitted from substation transmitters (STR) to a main station receiver (MREC) and from a main station transmitter (MTR) to substation receivers (SREC) respectively. The main station includes a transmission timer arrangement (TTM) to time the operation of the main station transmitter and of each of the substation transmitters to avoid concurrent receipt by each one of the substation receivers of a second information packet sent thereto and of disturbing packets resulting from a first information packet sent by the corresponding substation transmitter. These disturbing packets can be reflected first packets or can result from crosstalk between the substation transmitter and the corresponding substation receiver.
