Problems solved by technology

The advantage of this solution is that the OSA packaging process is relatively simple and the cost is low; the disadvantage is that 4 OSAs plus DEMUX need to take up a lot of space in the module, which cannot meet the requirements of increasingly smaller modules
The disadvantage is that this packaging process is more complicated and more difficult than the conventional OSA packaging process
In addition, because the price of the high-speed ceramic BOX shell is much higher than that of the conventional TO base and the conventional machined metal tube body, it is difficult to reduce the cost of the device

Abstract

The invention discloses a light receiving module, which comprises a beam collimator for shaping an external input beam into a collimating beam, a wavelength division demultiplexing filter set for decomposing the beam after being collimated into multiple single wavelengths, detector TO assemblies for receiving and detecting light signals of the single wavelengths and a metal tube body for packaging the light receiving module. The light receiving module of the invention is used for 4x10G / 4x25G and comprises the beam collimator, the metal tube body, the wavelength division demultiplexing filter set and the multiple detector TO assemblies. Directions and positions of incident beams are decomposed and adjusted through the wavelength division demultiplexing filter set, and the multiple detector TO assemblies and the metal tube body are packaged together to realize functions of 4x10G and 4x25G ROSA light devices. The light receiving module of the invention has the advantages of simple OSA packaging implementation process and low cost in the first scheme and device miniaturization packaging in the second scheme.

Description

Technical field [0001] The present invention relates to the field of optical communication technology, and in particular to an optical receiving component, which is mainly applied to a 4x10G / 4x25G optical communication system. Background technique [0002] With the continuous development of new high-bandwidth services and the increasing maturity of high-speed transmission technologies, application requirements based on 40G / 100G high-speed transmission are becoming more and more obvious. Compared with traditional 10G, 40G / 100G has obvious advantages: higher efficiency and higher bandwidth. . 40G / 100G optical modules mostly use multi-channel optical transceiver technology (4x10G, 4x25G), and transmit data at a rate of 10G or 25G per channel, and their capacity is 4 times that of traditional single-channel modules. Optical modules for 40G / 100G transmission generally require optical devices to meet the requirements of ensuring airtightness, and there are usually two schemes for meet...
