ABSTRACT:
In an optical communication system, transmitter/receivers located remote from each other have an identical construction and are accurately positioned relative to each other by means of photodetectors. Each apparatus includes a transmitter section and a receiver section which are disposed in a common transparent housing. Such a construction is applicable even to a repeater between the remote apparatuses by building another set of transmitter and receiver sections in the apparatus.
