Patent number: 11841536Abstract: A bi-directional optical communication device comprising a reduced number of components for speedier and less costly manufacture includes a plate and a wavelength-division multiplexer disposed on the plate. An optical-signal transmitter disposed on the board emits first beam to the wavelength-division multiplexer and an optical-signal receiver disposed on the board detects the second beam emitted by the wavelength-division multiplexer. An optical receptacle is disposed on the plate for actual connection to an optical fiber. The optical fiber emits the second beam to the wavelength-division multiplexer, and the multiplexer emits the first beam to the optical fiber.Type: GrantFiled: December 27, 2022Date of Patent: December 12, 2023Assignee: SHUNYUN TECHNOLOGY (ZHONG SHAN) LIMITEDInventor: Jie Huang
