"CWD M4-OCP-100G" with a reach of 500m, started to be widely distributed as a low-priced 100G Ethernet standard

"OCP" launched by Facebook

This week we're talking about OCP standards. In the list shown in the previous article, "Looking back on the optical Ethernet standards so far and the background of the discussion on" 40GBASE-FR "", I introduced that there are the following three standards for OCP.

Besides this, there was also a 100G CWDM4-OCP. I would like to explain these in order.

First of all, about OCP (Open Compute Project). The project was launched by Facebook (now Meta), but the first design started in 2009. It was released in the form of OCP in 2011, and the project started from here.

Fortunately, there are various articles on OCP itself in the companion magazine "Cloud Watch", but the circumstances before and after the launch are easy to understand, "Is it the flow of data center standardization?" OCP "aiming to open source his hardware" ..

In short, OCP is an organization that provides the de facto standard not only for Facebook but also for companies that want to set up their own servers and vendors who want to introduce the system to such companies, and there are not only server specifications but also server specifications. It also includes network switches and Ethernet itself.

OCP is showing a direction to actively adopt it even if it is not necessarily standardized if compatibility and interoperability are guaranteed, and in that sense, with various MSAs introduced in the past. We are in a very close position.

The OCP first released on January 9, 2017, "Facebook: CWDM4-OCP 100G Optical Transceiver Specification". By the way, this is Spec Version 0.1, but it is shared in this state, and it is almost confirmed by this content. OCP doesn't seem to care about raising Version to 1.0 properly like IEEE.
