In our new data center builds we're transitioning from MMF to SMF for the tie cabling between networking gear in the MDF/IDF racks to the server racks. Today those interconnects are short (under 100 meters) 10GE and 40GE-LX4 over MMF. We’re transitioning to SMF to support services beyond that, such as 100GBASE-LR4. Would G.652.D be the right specification for the infrastructure tie cabling? Are there other considerations around this? Thank you
