Summary

Pro-optics has introduced a product line of high-speed optical modules designed for immersion-cooled data centers, offering a substantial reduction in data center PUE and energy consumption.

Utilizing Pro-optics' advanced COB platform and cutting-edge liquid cooling sealing technology, the new product line meets the specific demands of immersion-cooled data centers. Key features of this product line include:

• Optimization design for RF and heat dissipation
• Reliability verification design
• EMI-processed structural design
• Highly integrated multi-channel optical system design
• Fast COB multi-channel automatic coupling design

For packaging, Pro-optics employs a fully automated process and low-temperature, low-pressure glue filling technology. The optical connectors of these modules utilize the Cable Pigtail method to relocate the optical interfaces outside the liquid.

Pro-optics has established a comprehensive design and manufacturing platform for liquid-cooled optical modules to ensure high performance and reliability. Future plans involve collaboration across the industrial chain to standardize and industrialize liquid-cooled optical modules, providing high-performance solutions for inter-device connections within high-density data centers and enhancing the value of immersion-cooled data centers.

Product Introduction

The Pro-optics immersion-cooled optical module product line comprises three products, each supporting Ethernet and Infiniband applications with working rates of 25G NRZ, 50G PAM4, and 100G PAM4:

• 100G QSFP28 SR4 MPO pigtail (4x 25G NRZ)
• 200G QSFP56 SR4 MPO pigtail (4x 50G PAM4)
• 400G QSFP112 SR4 MPO pigtail (4x 100G PAM4)

Liquid Cooling Process Platform

Pro-optics' liquid cooling process platform offers the following advantages:

• Automated liquid cooling sealing packaging process
• Fully automated packaging and coupling technology
• High product reliability tailored for "cloud computing" data centers

Advantages of Liquid Cooling Data Centers

Compared to traditional air-cooled data centers, liquid-cooled data centers provide the following benefits:

• Higher heat dissipation efficiency: Liquid carries away heat at a rate 3000 times higher than air
• Faster heat transfer: Liquid's thermal conductivity is 25 times greater than that of air
• Lower noise levels: Liquid cooling systems produce 10~15dBA less noise compared to air cooling systems
• Energy and power savings: Liquid cooling systems are approximately 30% more energy-efficient than air cooling systems
• Lower PUE: Liquid-cooled data centers achieve a PUE close to 1.05, or even lower, compared to 1.3-1.5 for air-cooled data centers

Market Outlook

With the increasing adoption of AIGC technology, the demand for high-speed optical modules is growing rapidly, accompanied by higher power density, heat generation, and energy consumption challenges. Immersion-cooled data center technology is gaining traction in the industry and is expected to generate revenue from liquid-cooled optical modules by 2024. Pro-optics' full range of liquid-cooled optical modules will play a crucial role in helping data centers overcome energy efficiency barriers.
