Embodiment
[0031] like image 3 As shown, the optical transceiver module assembly that is conducive to improving the coupling efficiency includes a transmitting end 1, a first optical filter 21, a second optical filter 22, a third optical filter 23, a first receiving end 31, and a second receiving end 32 , public port 4;
[0032] The transmitting end 1 includes a laser chip 11 for generating laser light, a positive lens 12 and a negative lens 13. The first optical signal λ1 emitted by the laser chip 11 is converged by the positive lens 12 and then enters the negative lens 13, and is transformed into parallel light by the negative lens 13 to exit , reaches the first filter 21, reaches the second filter 22 after being reflected by the first filter 21, and is received by the first receiving end 31 after being transmitted by the second filter 22, while obtaining parallel light, The focal length of the positive lens 12 and the negative lens 13 is relatively long. During the adjustment of the...

The invention discloses an optical transceiver module component favorable for improving coupling efficiency, the component comprises: a transmitting terminal, a first optical filter, a second optical filter, a third optical filter, a first receiving terminal, a second receiving terminal and a public port; the transmitting terminal comprises a laser chip for generating laser, a positive lens and a negative lens, a first optical signal emitted by the laser chip is converged through the positive lens and enters in the negative lens to convert into parallel light to exit, and the light is received by the first receiving terminal; a second optical signal is received by the second receiving terminal; a third optical signal emitted by the laser chip is converged through the positive lens and enters in the negative lens to convert into parallel light to exit, the light reaches the first optical filter, is transmitted through the first optical filter and is received by a public port optical fiber. A multi-wavelength component provided by the invention can acquire relatively high coupling efficiency through relatively short optical path length and relatively small volume, and problems of adjacent wavelength interference and unable effective separation are solved.
Description
technical field [0001] The invention relates to an optical transceiver module assembly in the technical field of optical fiber communication, in particular to an optical transceiver module assembly which is beneficial to improving coupling efficiency. Background technique [0002] With the application of optical fiber network becoming more and more popular, especially the gradual implementation of fiber access FTTH (Fiber To The Home) projects around the world, as well as point-to-point data transmission, especially the promotion of triple play, and fiber-to-the-home network from EPON And GPON is upgraded to the next-generation fiber-to-the-home network (NGPON1 is divided into XGPON and 10GEPON), and there is a mixed networking situation, and the demand for optical fiber components in the market is also increasing. [0003] For example, in the XGPON standard, the wavelengths to be processed are 1270nm and 1577nm. Compared with 1310nm and 1490nm in the original GPON standard,...
