We should keep in mind that as POET focused on 400G that effort is applicable to 100G especially associated with CWDM applications that have never been available at low cost before. So although we here have been focused on 400G there will be a lot of companies that are not ready for that yet and a low cost CWDM 100G solution is required for their immediate needs.
I believe POET's plans are to cover all bases with everything utilizing the OI platform.
