I'm currently searching out options for providing carrier ethernet demarc at 10Gbps and 25Gbps port speeds to evaluate for some upcoming projects. 10Gbps options abound, but it seems like the next step up with most vendors is 100Gb handoff. I'm not having much luck finding 25Gbps options other than ADVA/Adtran FSP 150-XJ128 and FSP 150-XG404 variants.
Currently the majority of our customers are PON based (Calix), and we have non-PON handoffs with smaller Juniper switches as the demarc, so we're looking to step up to something actually designed for this purpose. We'd like to be able to perform y.1564 testing and use MEF compliant devices. I'm reaching out to some vendors/resellers to see what options they can provide, but I'm interested in hearing real-world experiences with different vendors in this space and especially any recommendations on the 25Gb demarc, as we have had some specific requests for that port speed recently. Feel free to reach out off list if that's your preference. John Stitt
