With the rapid development of generative AI technology, the demand for computing power centers has soared, making high-speed 800G/400G optical modules a critical part of the industry chain. Due to the variability in implementation among different manufacturers, compatibility and interoperability of optical modules have become new challenges. To address these issues, the OIF (Optical Internetworking Forum) has developed the Common Management Interface Specification (CMIS) to support the management and control of pluggable optical modules, providing essential support for their interoperability.

However, each manufacturer’s understanding and implementation of the CMIS protocol vary, leading to common issues during R&D, such as abnormal state machine transitions, irregular register reads/writes, and timing performance discrepancies, affecting development progress. During sample delivery, optical modules often fail to be recognized or matched on the customer’s equipment, affecting the success rate of sample acceptance. The industry has long lacked a specialized CMIS analysis and testing tool to identify, analyze, and resolve these issues. To address this challenge, HYWICOM has innovatively developed the CMIS analysis tool, aiming to provide customers with comprehensive and efficient analysis and testing solutions. Its main features include:

Comprehensive Coverage: Supports testing of all relevant content in CMIS versions 3.0-5.2.

Rich Content: Over 500 functional point tests, including registers, state machines, and timing performance detection with an accuracy of up to 1 millisecond.

Simple and Efficient: One-click activation of the CMIS full-feature test, not only easy to operate but also greatly improving testing efficiency.

Flexible Customization: Offers a rich and convenient API to help users write their own test scripts according to specific needs and standards, achieving customized testing.

Analysis Reports: Automatically generates analysis reports, clearly presenting fault issues.

HYWICOM’s 800G network tester FRAEO 8800 has set multiple industry firsts and has been extensively and thoroughly verified in 800G/400G optical module testing, becoming the industry’s preferred 800G traffic tester. Its main features include:

Industry’s First Mixed  Multi-Port 800G Design: The advanced hardware system architecture natively supports dual-port 800G QSFP-DD800 and dual-port 800G OSFP800, meeting various traffic testing applications such as loopback, peer-to-peer, optical cable/cable, breakout, and switch interconnection. One FRAEO 8800 tester is equivalent to multiple 800G testers on the market, making hybrid multi-port 800G the industry’s consensus as the best configuration for 800G traffic testers.

Industry’s Only “Three All” (All Rates, Full Compatibility, All Ethernet Speeds) Tester: 1. Seamless switching of full rates 112G PAM4, 56G PAM4, 28G/10G NRZ; 2. Fully downward compatible with all optical module encapsulation types of OSFP and QSFP; 3. Full application support for various Ethernet traffic modes (800GE – 10GE). The innovative “Three All” design allows one FRAEO 8800 to cover the functions of three traffic testers (800G, 400G, 100G), significantly reducing repeated equipment investment and saving costs.

Support for Line-Side Pluggable Coherent Optical Module Testing: Provides sufficient power supply and reliable heat dissipation design to support the testing of 800ZR / 400ZR DCO coherent optical modules.

HYWICOM’s 800G network tester, pioneering the development of the CMIS analysis tool, provides reliable, comprehensive, and efficient optical module testing solutions for AI computing power centers.
