Thanks for your question here. Sorry to tell you for 100GBASE-SR4 in FS.COM, it can not work on speed of 50GB. As for 40GB, they can only work on limiting devices. For further details, you can send email to sales@fs.com to learn more. If you need 40GB rate transceivers, FS.COM can offer. Just click
here. Besides, currently, there are few 100G transceivers from some main optical products suppliers can support 40GB, and most of them can only work with their own brand of the device.
