OIF advances CEI-224G-Linear project

OIF has launched a new CEI-224G-Linear project built on the approach of CEI-112G-Linear in terms of specification methodology. It will support 224G full linear optical modules for next-gen applications (e.g., Ethernet, Ultra Ethernet Consortium (UEC), Artificial Intelligence/Machine Learning [AI/ML]) with low power, cost/complexity and latency. The TP1/TP1a and TP4/TP4a electrical specifications will enable up to 224G full linear optical modules for Linear Pluggable Optics (LPO), co-packaged optics (CPO) and Near Package Optics (NPO), supporting next-generation application requirements.

“The CEI-224G-Linear project will represent significant progress in our technological capabilities, weaving the precision of CEI-112G-Linear with groundbreaking innovations,” said Mike Li, OIF Board Member and Intel. “By enabling 224G full linear optical modules and leveraging the advanced 224G DSP SERDES architecture and technology, this initiative is poised to redefine the landscapes of Ethernet, UEC and AI/ML applications. As we embrace lower power, cost and latency, this project is a giant step forward in next-generation computing and connectivity driven by AI/ML.”


At its Q2 Technical and Market Awareness & Education (MA&E) Committees meeting, held May 7-9 in Athens, Greece, the OIF also launched a Common Electrical I/O (CEI) CEI-224G-Linear project and the publication of two Common Management Interface Specification (CMIS) white papers.

Additionally, the Physical Layer User Group (PLUG) Working Group released a new system vendor requirements document for Energy Efficient Interfaces (EEI).

Common Management Interface Specification (CMIS) White Paper on Management of Smart Optical Modules

  • This white paper explores how the DWDM functions, parameters and operational aspects of “smart” optical pluggable modules can be handled more efficiently to address various challenges. It introduces an alternative control paradigm for optical modules that decouples optical layer control from packet layer control and from host software and packet controller software development and outlines the pros and cons of this approach. This paradigm is called “host independent management,” enabling advanced capabilities of smart optical modules via additional management methods. The white paper is available for download here.

CMIS-Based Out-of-Band Messaging for Link Training

  • This white paper provides background on link training and a proposed message catalog by which any transmit SerDes can be trained initially (or tuned adaptively while in service) based on the needs of the corresponding receive SerDes, with the help of message exchange.It promotes out-of-band (OOB) messaging via the ubiquitous CMIS management link as a flexible solution for exchanging link training messages. The technical specifications of the messaging facility and the representation of the messages will be defined in a CMIS-LT supplement. Potential CMIS-LT applications could include CEI-112G Very Short Reach (VSR), Extra Short Reach (XSR), XSR+, and Medium Reach (MR), IEEE 802.3 AUI C2M links, Fibre Channel, InfiniBand, Optical Transport Network (OTN), etc. Download the white paper here.

System Vendor Requirements Document for Energy Efficient Interfaces

  • In today’s fast-paced technological landscape, where data processing and communication demands for AI continue to soar, pursuing energy-efficient solutions is critical. This requirements document for EEI is a direct result of engaging with end users to understand their needs and expectations. It seeks to prioritize applications and establish fundamental criteria for the next generation of energy-efficient electrical and optical link projects and specifications.

“OIF’s commitment to interoperability standards and tackling technological challenges was evident at the Q2 meeting,” said Nathan Tracy, OIF President, and TE Connectivity. “The high attendance, start of the CEI-224G-Linear project, CMIS white papers, and the vendor requirements document for EEI, alongside David Moor’s insightful presentation on advanced transceiver design, underscore our leadership in promoting industry-wide collaboration and innovation.”

The event was further highlighted by guest speaker David Moor, a representative from ETH Z├╝rich and the FLEX-SCALE consortium. Moor discussed the development of an optical digital-to-analog converter (oDAC) supporting Tbps+ data rates with lower power per bit than conventional modulation methods. According to Moor, this design utilizes currently available electronics and photonic devices and is well suited to support high-capacity transport with improved power efficiency.

Cignal AI: 400 and 800GbE module shipments jump more than 25% QoQ

Hyperscale network operator demand drove purchases of 400GbE and 800GbE datacom and 400ZR telecom optical modules to record levels, according to the latest Optical Components Report from research firm Cignal AI. Well over 3 million high-speed datacom modules were shipped this quarter in support of AI cluster interconnect and traditional computing applications.

“800GbE vendor shipments have yet to match demand, though nearly as many 800GbE modules shipped in 1Q24 as in all of 2023,” said Scott Wilkinson, Lead Analyst at Cignal AI. “While some vendors have reported that lead times are coming down, the demand for 400GbE and 800GbE modules remains exceptionally strong and we anticipate that datacom segment revenue will double in 2024.”

Additional 1Q24 Optical Component Report Findings:

Spending on Datacom optical components was up more than 90% YoY as AI applications of 400GbE and 800GbE optical modules for AI applications drove demand to record levels.

Combined unit shipments of 400GbE and 800GbE Datacom modules across all SR/DR/FR/LR specifications jumped over 25% QoQ. Innolight led all vendors in shipments of Datacom modules.

Telecom optical module shipment growth was concentrated in 400G coherent pluggables, which were up more than 35% YoY. Marvell and Acacia experienced strong shipment growth.

Outside of pluggable coherent, shipments of Telecom components declined YoY, with segment revenue dropping -26% YoY.

The coherent module market size declined to under $5 billion in 2023 but it will grow in 2024 and is expected to approach $10 billion in 2028.
