Abstract:
1. A bi-directional optical transceiver module comprising: an optical transmitter, which has a TO-can structure, that generates a first optical signal; a plurality of optical receivers, which has a TO-can structure, that detects a second optical signal; a housing having a first receiving section that receives the optical transmitter, a second receiving section arranged to be opposite to the first receiving section, a third receiving section arranged below the first and second receiving sections to receive the optical receiver, a fourth receiving section arranged to be opposite to the third receiving section, and holes formed in the housing to communicate the first through fourth receiving sections; an optical fiber ferrule received in the second receiving section, the optical fiber ferrule including an optical fiber that inputs the second optical signal into the bi-directional optical transceiver module and outputs the first optical signal from the bi-directional optical transceiver module; and a plurality of blocks arranged in a path of the second optical signal, each of the blocks being received in the fourth receiving section that supports a filter to output the first optical signal to the second receiving section and reflects the second optical signal received from the optical fiber at a predetermined angle with respect to an optical path of the first optical signal, and supports a mirror to reflect the second optical signal reflected from the filter to the optical receiver; wherein a number of said plurality of blocks corresponds to a number of different-wavelength channels forming the second optical signal, and optical receivers respectively corresponding to the blocks.
