Abstract

The invention discloses a low-cost QSFP28 SR4 COB process optical module, which comprises a laser driving LDD for driving a laser device to emit light, and a trans-impedance amplifier TIA used for amplifying a current signal, wherein a vertical cavity surface laser array VCSEL Array is formed by four single-channel first optical chips connected with the LDD in space; and a photoelectric detector array PD Array is formed by four single-channel second optical chips connected with the TIA in space. The low-cost QSFP28 SR4 COB process optical module provided by the invention adopts a COB (chip onboard) process, uses four single 25G VCSELs (vertical cavity surface lasers) and four single 25G PDs (photoelectric detectors) to respectively replace one traditional four-channel 25G VCSEL Array (vertical cavity surface laser array) and one four-channel PD Array (photoelectric detector array), adopts the same application circuit, can reduce the material cost by about 15%, and in addition, can reduce the repair cost.

Description

technical field [0001] The invention relates to the field of optical communication. More specifically, the present invention relates to a low-cost QSFP28 SR4COB process optical module. Background technique [0002] As the market's requirements for data transmission rates are getting higher and higher, optical modules with higher rates are also born. In the current high-speed optical module market, 100G optical modules are the mainstream products in the optical communication market. 25G servers and 100G switches can be seen everywhere in ultra-large-scale data centers. They have gradually replaced the previous 10G servers and 40G switches. 25G / The 100G upgrade mode has become an important path for data centers. QSFP28 SR4 optical modules have become the leading role in data centers, and the demand will increase significantly. At present, the competition in the optical module industry is fierce, and the cost advantage can greatly improve the competitiveness of the industry. ...
