Solution:

Yes, we do. STM-xxx (SDH) is a standard in the EU. The equivalent in the US and Canada is OC-xxx (SONET). STM-64 = OC-192. Please note that these are telecom standards. We do offer a product with XFP ports. It is the iMcV 10G XFP/XFP. The product number is 860-12100. Go to the product page on the B&B Website http://www.bb-elec.com/Products/Ethernet-Media-Converters/Mode-Converters/iMcV-10G-Converter-XFP.aspx Download the manual and look through it for verbiage at the DIP Switch settings. OC-192 is one of the protocols listed in the DIP Switch section.
