PURPOSE:To attain optical fiber communication by one kind of optical transmitter/receiver independently of master/slave equipments by changing over the mode into the reception mode so as to allow the system to be in standby with the data reception from an opposite equipment after the data is sent with the transmission mode. CONSTITUTION:An optical transmitter/receiver 1 consists of an optical transmitter/receiver 2 executing transmission/reception of a data to an optical fiber and a controller 3 composing of a CPU controlling the transmission/ reception of the optical transmitter/receiver 2. When a power at the station A is applied at a point of time tA, after an optical transmitter/receiver of a station A sends a data (a) with the transmission mode at first and is in standby with the data reception from an opposite station B while the mode is switched to the reception mode. The optical transmitter/receiver of the station A receives a data (b), is brought into the transmission mode and sends next a data C, is switched to the reception mode to be in standby with the data reception from the opposite station B. Thus, one kind of the optical transmitter/receiver is to be manufactured, the mass-production cost is made cheaper and the handling and management are facilitated. |
