The CFP Multi-Source Agreement (MSA) defines hot-pluggable optical transceiver form factors to enable 40Gb/s, 100Gb/s and 400Gb/s applications, including next-generation High Speed Ethernet (40GE, 100GE and 400GE). Pluggable CFP, CFP2, CFP4 and CFP8 transceivers will support the ultra-high bandwidth requirements of data communication networks that form the backbone of the internet. The most recent CFP8 transceiver form factor provides for a very versatile platform that can support a broad range of PMD’s at 400G, and importantly offers a path to products in the future that are capable of supporting 800Gb/s.
