Abstract

The invention discloses an optical module, which belongs to the technical field of optical communication systems. The optical module includes: n lasers, n collimating lenses, a wavelength division multiplexer and a housing, wherein n is an integer greater than 1; the n collimating lenses and the wavelength division multiplexing The laser emission direction is fixedly arranged in the housing in turn, wherein the n lasers and the n collimating lenses are arranged in one-to-one correspondence, and the distance from each of the n lasers to the corresponding collimating lens is equal , and the laser light emitted by each laser is directed to the wavelength division multiplexer through the corresponding collimating lens, and the distance between any two adjacent lasers among the n lasers and the light receiving plane of the wavelength division multiplexer is not equal. The invention improves the heat dissipation capability of the optical module. The invention is used to deliver laser light.

Description

technical field [0001] The invention relates to the technical field of optical communication systems, in particular to an optical module. Background technique [0002] In the field of high-speed data communication, optical modules include: lasers, collimating lenses, wavelength division multiplexers, shifting prisms, focusing lenses and adapters, etc. The laser output with a certain power can pass through collimating lenses, wavelength division multiplexers, The displacement prism and focusing lens are injected into the adapter, and then the laser light is guided into the receiving end of the optical fiber through the adapter, and then the laser light is transmitted through the optical fiber. [0003] related technologies, such as figure 1 As shown, the optical module 00 specifically includes a housing (not shown in the figure) and 4 lasers 001, 4 collimating lenses 002, 1 wavelength division multiplexer 003, 1 displacement prism 004 and 1 A focusing lens 005, wherein, 4 l...
