OIF will spotlight optical networking interoperability and collaboration during ECOC 2025

When OIF comes to ECOC 2025, its multi-vendor demonstration will once again show how its members are bridging critical gaps and accelerating innovation through collaboration and interoperable standards-based solutions.

Featuring 35 participating companies, the demo encompasses several of OIF’s core technical domains — optical, electrical, energy efficient and management interfaces — and highlights interoperability across key technologies including 400ZR, 800ZR, Multi-span Optics, Common Electrical I/O (CEI) CEI-448G, CEI-224G, CEI-112G, Co-Packaging, Common Management Interface Specification (CMIS) and Energy Efficient Interfaces (EEI).

One of this year’s latest developments is that CMIS will operate within a live, simulated network environment rather than as a standalone configuration.

OIF noted this shift reflects the specification’s maturity and its critical role in enabling plug-and-play integration across disaggregated systems, delivering real-world value to both operators and system vendors.

“OIF’s interoperability work is grounded in collaboration — across suppliers, hyperscalers, system vendors and network operators,” said Mike Klempa, OIF Board and Physical and Link Layer (PLL) Interoperability Working Group Chair (Alphawave Semi).
