COBO: specification work nearing completion

The Consortium for On-board Optics (COBO) is on target to complete its specifications work by the year end. The work will then enter a final approval stage that will take up to a further three months.

On-board optics, also known as mid-board or embedded optics, have been available for years but vendors have so far had to use custom products. The goal of COBO, first announced in March 2015 and backed by such companies as Microsoft, Cisco Systems, Finisar and Intel, is to develop a technology roadmap and common specifications for on-board optics to ensure interoperability.

Brad Booth (pictured), the chair of COBO and principal architect for Microsoft’s Azure Global Networking Services, says that bringing optics inside systems raises a different set of issues compared to pluggable optical modules used on the front panel of equipment. “If you have a requirement for 32 ports on a faceplate, you know mechanically what you can build,” says Booth.

COBO looks inside and beyond the data centre 

The Consortium of On-Board Optics is working on 400 gigabit optics for the data centre and also for longer-distance links. COBO is a Microsoft-led initiative tasked with standardising a form factor for embedded optics.

Established in March 2015, the consortium already has over 50 members and expects to have early specifications next year and first hardware by late 2017.

Brad Booth, the chair of COBO and principal architect for Microsoft’s Azure Global Networking Services, says Microsoft plans to deploy 100 gigabit in its data centres next year and that when the company started looking at 400 gigabit, it became concerned about the size of the proposed pluggable modules, and the interface speeds needed between the switch silicon and the pluggable module.

“What jumped out at us is that we might be running into an issue here,” says Booth.
