OFC 2025
The Ethernet Alliance put on one of the organization’s most popular interoperability demonstrations at OFC in San Francisco, CA. The Ethernet Alliance’s OFC 2025 exhibit showcased Ethernet’s evolution in speed, efficiency, and performance. From 10 gigabit Ethernet (10G) to 800G, Common Management Interface Specification (CMIS), Auto Negotiation Link Training (ANLT), and cutting-edge AI-driven technologies such as congestion control and SmartNIC load balancing will be on display. Additionally, innovations like 224 Gbps electrical signaling, Linear Pluggable Optics (LPO), liquid cooling for high-efficiency networking, and a broad range of interconnects – including OSFP, QSFP-DD, QSFP, ZR, OpenZR+, and SFP – showed how Ethernet is setting new performance standards for next-gen networks.

Ethernet Alliance panel discussion:
Date/Location: Wednesday, April 2, 10:15 – 11:15 am – Theater II
Title: Will the Complexity and Higher Link Speeds of Hyperscale Data Centers Hinder Interoperability? Challenges Arising from Specification Compliant Conformance Across the High-Performance Compute Market and their Potential Impact on Ethernet Interoperability.
Description: A hallmark of the Ethernet Alliance’s mission, and generally the overall Ethernet ecosystem, is the promise of device and vendor interoperability. Over the 50+ year history of Ethernet, the market has evolved away from the single source suppliers in favor of a more competitive, yet interoperable solution set. The focus of today’s hyperscale compute environment is optimization for speed, i.e. qualifying preferred or optimized interconnect suppliers at the exclusion of others. Ethernet has come a long way from the days of Novell Networks or Banyan Vines where all in one solutions came ready to run from a single vendor. Specialization in various disciplines of the industry offered customers better components, but also included a “roll your own” integration
