Abstract
A bidirectional light transmitting and receiving device includes a first light transceiver having a first light emitter and a first light receiver for receiving a light beam entering around the first light emitter, and a second light transceiver having a second light emitter and a second light receiver for receiving a light beam entering around the second light emitter, and signal transmission and reception between the corresponding first and second light device units is achieved through the same optical passageway. The bidirectional light transmitting and receiving device has a simple configuration because optical signal transmission and reception are achieved through the single optical passageway. The number of optical fibers required for the signal transmission and reception in the device is reduced by half, and thus the manufacturing cost also becomes lower.
