Problems solved by technology

At present, with the increase of the communication distance between data centers, the requirements for the communication distance between modules are getting higher and higher. The original multi-channel multi-mode parallel optical module can no longer meet the requirements of communication distance, and the multi-channel single-mode parallel optical module should be used. However, the multi-channel single-mode parallel optical module is limited by the volume and number of channels of coaxial packaged TOSA and ROSA optical components, and it is increasingly unable to meet the needs of the development of modules in the direction of high integration and small volume.

Abstract

The invention discloses a multichannel parallel optical receiving module, and the optical receiving module comprises a housing, a substrate, an MT connector, a ceramic terminal, and a flexible circuit board. The substrate is disposed in the housing. The substrate is provided with an optical fiber collimation array, a focusing lens and an L-shaped gasket, wherein the optical fiber collimation array, the focusing lens and the L-shaped gasket are set sequentially. A side surface of the L-shaped gasket is provided with a photoelectric detector PD, and a receiving drive chip is disposed above the L-shaped gasket. The photoelectric detector PD and the receiving drive chip are connected through bonding. The optical fiber collimation array, the focusing lens and the photoelectric detector PD achieve the optical path coupling. According to the invention, the module employs a fewer optical devices, can greatly reduce the coupling difficulty of the optical path, reduces the technological difficulty and requirements during the production of the module, is easier to assemble, improves the production efficiency of the module, facilitates the batch product, and can achieve the airtightness.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a multi-channel parallel light receiving component. Background technique [0002] In the field of data communication, in order to improve the transmission bandwidth of information and enhance the throughput of data, on the one hand, to increase the communication capacity of a single channel, wavelength division multiplexing technology is often used, and wavelength division multiplexing optical modules are used; Quantity, parallel transmission technology is often used, and multi-channel parallel optical modules are used. At present, with the increase of the communication distance between data centers, the requirements for the communication distance between modules are getting higher and higher. The original multi-channel multi-mode parallel optical module can no longer meet the requirements of communication distance. The multi-channel single-mode parallel optic...
