Abstract

An optical transmission subassembly and its manufacturing method are suitable for converting an electrical signal into an optical signal. The optical transmission subassembly includes an optical waveguide element, a plurality of laser diodes, a plurality of first focusing lenses, a second focusing lens, and a fiber optic socket . When these laser diodes are excited, they emit laser light, which is coupled to multiple input ends of the optical waveguide element through the first focusing lens, and the optical waveguide element guides the laser light from the input ends to the output end, and the laser light emitted from the output end passes through The second focusing lens is coupled into the first end of the optical fiber socket, whereby multiple laser diodes can integrate and convert multiple electrical signals to be transmitted into an optical signal to be output by the optical fiber socket.

Description

technical field [0001] The invention relates to an optical communication component, in particular to an optical transmission sub-assembly (TOSA, transmitting optical sub-assembly). Background technique [0002] At present, the optical fiber network that has been widely used in long-distance backbone networks in many countries around the world is mostly systems that provide 2.5Gbps (Giga bit per second), 5Gbps, or 10Gbps. For broadband, high-capacity, and high-speed network systems, wavelength-division-multiplexing (WDM) and high-density wavelength multiplexer (DWDM, Dense Wavelength Division Multiplexing) architectures have been proposed in the prior art. The existing optical transmission device mainly uses a demultiplexer (Demultiplexer). The demultiplexer disperses the light with different wavelengths in the same optical fiber to different optical fibers and must have excellent splitting ability and narrow-band (Narrow -Band) optical components. [0003] However, the dat...
