CFP

The CFP Multi-Source Agreement (MSA) defines hot-pluggable optical transceiver form factors to enable 40Gb/s and 100Gb/s applications, including next-generation High Speed Ethernet (40GbE and 100GbE) for telecom and datacom application. CFP optical transceiver supports transmission on a single-mode and multi-mode fiber at a variety of rates, protocols, and link lengths, including all the physical media dependent (PMD) interfaces included in the IEEE 802.3ba standard. CFP was designed after the Small Form-factor Pluggable transceiver (SFP) interface, but is significantly larger to support 100Gbps data transmission. The electrical connection of a CFP is based at 4 lanes at 10Gbps (for 40G), respectively 10 x 10 Gbps (for 100G) in each direction (RX, TX). The optical connection can support both 10 x 10Gbps and 4 x 25Gbps variants. CFP transceivers can support a single 100Gbps signal like 100GE or OTU4 or one or more 40Gbps signals like 40GE, OTU3, or STM-256/OC-768. Link distances reach from a few meters to 40km.There are mainly three kinds of 100G CFP optical transceivers: CFP 100GBASE-SR10, CFP 100GBASE-LR4 and CFP 100GBASE-ER4. Telesail provides OEM compatible CFP LR4 ER4 optical transceiver modules for telecom and datacom application.
