With the need for energy conservation and carbon reduction in data centers and the development of high-density data centers, liquid cooling has become a standard feature of data centers, and data centers have officially entered the era of liquid cooling.

Recently, the 400G QSFP112 SR4 liquid-cooled optical module of Crealights Technology won the Excellent Technology Award of the 9th Xunshi Hero List in 2022.

The 400G QSFP112 SR4 liquid-cooled optical module is a high-speed optical module product independently designed and developed by Crealights Technology, which can meet the requirements of immersion applications. It is based on Crealights Technology's mature and stable COB platform and the leading liquid-cooling sealing technology in the industry. With core technologies such as RF, heat dissipation optimization design, reliability verification design, EMI processing structure design, highly integrated multi-channel optical system design, and rapid COB multi-channel automatic coupling design, it stands out among many excellent products, providing high-performance and high-bandwidth solutions for interconnection between devices within a distance of 100 meters in high-density data centers. It also creates added value for the data center.

This award fully affirms Crealights Technology's leading position in the industry in terms of R&D strength, product quality, production capacity and quality control.

Crealights Technology Liquid Cooling Technology Integration Platform

Liquid cooling process platform

●  Liquid-cooling sealing process for single-mode/multi-mode products

●  Complete automated packaging coupling technology

●  The high reliability of the product can meet the demands of "cloud computing" data centers

The spatial optical coupling technology of traditional optical modules has solved the problems such as liquid leakage that will be faced in liquid-cooled environments, and has achieved its application in liquid-cooled environments. In terms of structure, the light output method differs from the traditional air-cooled optical module. It adopts the cable method to move the connector outside the liquid.

Reliability verification platform

●  Based on the transformation of the airtight platform, the reliability requirements of the liquid cooling environment are met

●  Customized reliability testing equipment to meet the special reliability testing requirements of liquid-cooled optical modules

Due to the fact that immersion liquid cooling technology still lacks large-scale application cases in data centers and there are no corresponding national or industry standards. At present, the reliability test standard for immersion liquid-cooled optical modules, which is being discussed and formulated with the participation of Crealights Technology, is under development.

Liquid-cooled detection platform

●  Liquid cooling testing platform: Customized liquid cooling testing environment to meet the various testing index requirements of optical modules.

●  Routine testing of liquid-cooled optical modules: Meeting EVT and DVT testing standards

●  Liquid-cooled optical module reliability testing: Conventional reliability testing, as well as liquid-cooled TC, pressurized, high-temperature and other reliability tests

●  Liquid-cooled optical module switch testing: Immersive switch hanging test

The Crealights Technology liquid cooling technology integration platform, through the liquid cooling process platform, reliability verification platform and liquid cooling detection platform, on the basis of compatibility with the existing industrial chain and based on the stable and mature COB process platform, makes the reliability and heat dissipation performance of the products excellent, reaching the leading level of similar optical module products, providing sufficient guarantee for the research and development of immersion liquid-cooled optical modules.

With its efficient refrigeration, mature technology and cost advantages, the development prospects of liquid cooling, especially immersion liquid cooling, are beyond doubt. In the future, Crealights Technology will release a full range of liquid-cooled optical modules, directly reducing the operating costs of data centers, improving computing efficiency, and promoting the green development of data centers.
