The document discusses scaling datacenter bandwidth with 400G and 800G Ethernet. It describes how 100G Ethernet is ramping up fast with over 5 million ports expected in 2017. Future solutions for high density 100GE to servers are presented, including 400G-DR4 optics that can provide up to 128 100GE ports per rack unit using 8 single mode fibers. Other 400G and 800G OSFP transceiver options are shown ranging from 2km to 10km distances using different cable types and lane configurations. Backward compatibility between OSFP and QSFP is enabled through an adapter.
