PROBLEM TO BE SOLVED: To provide an optical transmission reception system and a transmitter receiver where power consumption is reduced compared with a case for emitting light from a plurality of optical transmission units, regardless of whether or not a transmission path is connected, in a configuration for transmitting optical signals from the plurality of optical transmission units to the opposite device via a plurality of transmission paths.SOLUTION: An optical transmission reception system 1 includes a first transmitter receiver 2 having a plurality of first optical transmission units 21a-21d, and a first optical reception unit 22, and a second transmitter receiver 4 having a plurality of second optical reception units 41a-41d, and a second optical transmission unit 42. The first transmitter receiver 2 transmits an optical signal from some first optical transmission unit 21d, out of the plurality of first optical transmission units 21a-21d, and when the first optical reception unit 22 receives an optical signal from the second optical transmission unit 42, as a response to the optical signal, transmits an optical signal from remaining first optical transmission units 21a-21d, out of the plurality of first optical transmission units 21a-21d.SELECTED DRAWING: Figure 1 【課題】複数の光送信部から光信号を複数の伝送路を介して相手装置に送信する構成において、伝送路の接続の有無に関係なく複数の光送信部を発光させる場合と比べて消費電力を抑制した光送受信システム及び送受信装置を提供する。【解決手段】光送受信システム１は、複数の第１の光送信部２１ａ〜２１ｄ、第１の光受信部２２を有する第１の送受信装置２と、複数の第２の光受信部４１ａ〜４１ｄ、第２の光送信部４２を有する第２の送受信装置４とを備え、第１の送受信装置２は、複数の第１の光送信部２１ａ〜２１ｄのうちの一部の第１の光送信部２１ｄから光信号を送信するとともに、当該光信号に対する応答として第１の光受信部２２が第２の光送信部４２から光信号を受信した場合、複数の第１の光送信部２１ａ〜２１ｄのうち残りの第１の光送信部２１ａ〜２１ｃから光信号を送信する。【選択図】図１
