Advancing 800G SR8/DR8 Module Performance in High Temperatures: GIGALIGHT's 8-Channel Optics Mastery

SHENZHEN, China - Dec. 25, 2023 - PRLog -- GIGALIGHT, renowned for pioneering long-term research in 8-channel optics, has made a significant breakthrough in the realm of 800G optical modules.

The effectiveness of 800G optical modules relies heavily on the intricate harmony among 8-channel optical signal integrity technology, precise optical design, and meticulous form factor processes. Despite historically receiving less attention within the industry due to productivity and cost concerns, this technology marks a critical milestone in optical advancement, shaping the future landscape. While alternative technologies like 100G/200G PAM4 have been explored to bypass 8-channel optics, they might not align with strategic foresight. Looking forward, the limitless potential of wavelength division multiplexing in optics contrasts with the finite nature of its electronic counterpart. Nations grappling with underdeveloped semiconductor technologies should prioritize the advancement of analog-dominant wavelength division optical technologies.

The complexity of 800G optical modules resides in ensuring uniform high-temperature performance and channel consistency. Tailored for AI-intensive applications, these modules re-establish benchmarks for telecommunications-grade reliability. To fortify network robustness and preempt potential issues, advocating objective progress becomes imperative. While past trends witnessed data centers reducing reliability demands for interconnects, it posed consequential challenges.

GIGALIGHT's 800G SR8 supports two form factors: QSFP-DD and OSFP. It integrates high-performance 112Gbps VCSEL lasers and a 7nm DSP. The electrical host interface operates at 112Gbps PAM4 signal per channel, supporting the CMIS 4.0 protocol version. The module achieves a TDECQ of less than 3dB per channel, with an OMA RXsen sensitivity meeting -5.2dBm @ 2.4E-4 Pre-FEC 53.125GBd, enabling transmission distances of 60 meters (OM3 MMF) and 100 meters (OM4 MMF).

At the June 2021 Optical Communication Industry Summit Forum themed "Optical Linking Everything, Colorful Future," GIGALIGHT advocated for the continuous development of three key technologies:
- 8-channel optics
- Optoelectronic collaboration in 100G PAM4 technology
- Commitment to silicon photonics

GIGALIGHT has initiated small-scale production and global deployment of various 8-channel optical products across segmented markets.
