Document Type and Number:
WIPO Patent Application WO/2020/022553
Kind Code:
A1
Abstract:
A wavelength multiplexing bidirectional optical transmitting/receiving device according to one embodiment of the present invention comprises: a light transmitting block; an optical transmission band-pass filtering unit provided on one side of the light transmitting block; and an optical reception band-pass filtering unit provided on one side or the other side of the light transmitting block, wherein an optical transmission signal, passing through the optical transmission band-pass filtering unit so as to be incident on the light transmitting block, is reflected by the optical reception band-pass filtering unit and is discharged to the outside of the light transmitting block, and an optical reception signal, being incident from the outside so as to pass through the light transmitting block, passes through the optical reception band-pass filtering unit and is reflected by the optical transmission band-pass filtering unit.
