COBO targets year-end to complete specification

Part 3: 400-gigabit on-board optics

  • COBO will support 400-gigabit and 800-gigabit interfaces 
  • Three classes of module have been defined, the largest supporting at least 17.5W 

The Consortium for On-board Optics (COBO) is scheduled to complete its module specification this year.

A draft specification defining the mechanical aspects of the embedded optics - the dimensions, connector and electrical interface - is already being reviewed by the consortium’s members.

Brad Booth“The draft specification encompasses what we will do inside the data centre and what will work for the coherent market,” says Brad Booth, chair of COBO and principal network architect for Microsoft’s Azure Infrastructure.

COBO was established in 2015 to create an embedded optics multi-source agreement (MSA). On-board optics have long been available but until now these have been proprietary solutions. 

“Our goal [with COBO] was to get past that proprietary aspect,” says Booth. “That is its true value - it can be used for optical backplane or for optical interconnect and now designers will have a standard to build to.”

FPGAs embrace data centre co-processing role

Part 1: Xilinx's SDAccel development tool


The PCIe accelerator card has a power budget of 25W. Hyper data centres can host hundreds of thousands of servers whereas other industries with more specialist computation requirements use far fewers servers. As such, they can afford a higher power budget per card. Source: Xilinx

Xilinx has developed a software-design environment that simplifies the use of an FPGA as a co-processor alongside the server's x86 instruction set microprocessor.

Dubbed SDAccel, the development environment enables a software engineer to write applications using OpenCL, C or the C++ programming language running on servers in the data centre.

Briefing: Flexible elastic-bandwidth networks 

Vendors and service providers are implementing the first examples of flexible, elastic-bandwidth networks. Infinera and Microsoft detailed one such network at the Layer123 Terabit Optical and Data Networking conference held earlier this year.

Optical networking expert Ioannis Tomkos of the Athens Information Technology Center explains what is flexible, elastic bandwidth.

Part 1: Flexible elastic bandwidth


"We cannot design anymore optical networks assuming that the available fibre capacity is abundant"
