Problems solved by technology

Specifically, in short-distance transmission such as access network connection ports and data exchange in cloud computing data centers, 100G parallel optical modules require built-in data selectors and splitters, which makes the cost higher. Integrated data selectors and splitters Although the device has a long transmission distance, the process is complicated and the reliability is not high

Abstract

A 100G QSFP28 SR4 parallel optical transceiver module carries out data recovery processing on 100G electrical signals through a first clock data recovery module so that after continuing to modulate and demodulate the electrical signals after data recovery processing is carried out, an array driving module can drive a laser transmitting module to convert the electrical signals into optical signals, then the optical signals are coupled to an optical fiber and transmitted to a photovoltaic conversion module, the photovoltaic conversion module converts the received optical signals into electrical signals, four paths of 25G electrical signals output by a master control end are converted into four paths of 25G parallel optical signals through the photovoltaic conversion module, consequently, the 100G electrical signals are propagated in the form of the optical signals, an optical multiplexer is not needed, thus the size of the 100G QSFP28 SR4 parallel optical transceiver module is reduced, and the manufacturing technology is simplified. In addition, the invention provides a packaging method of the 100G QSFP28 SR4 parallel optical transceiver module.

Description

technical field [0001] The invention relates to a parallel optical module transceiver system, in particular to a 100G QSFP28 SR4 parallel optical transceiver module with a simple structure and a packaging method thereof. Background technique [0002] With the growth of network bandwidth, the 10G rate can no longer meet the transmission requirements of communication data, and the 100G transmission rate has become an inevitable solution in application networks such as telecommunication networks and data centers. When the electrical interface and protocol standards are clear and unified, the development of 100G QSFP+ is feasible in application. Specifically, in short-distance transmission such as access network connection ports and data exchange in cloud computing data centers, 100G parallel optical modules require built-in data selectors and splitters, which makes the cost higher. Integrated data selectors and splitters Although the device has a long transmission distance, th...
