CFP optical transceivers, also known as C form-factor pluggables, are common plug-and-play hot-swap transceivers. They were designed after the Small Form-factor Pluggable transceiver (SFP) interface, but CFP modules are significantly larger to support 100 Gigabit Ethernet systems (100Gbps).

  • The electrical connection of a CFP uses 10 x 10Gbps lanes 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.


TXO Optics offers a full range of CFP optical transceivers to meet your needs. All CFP optical transceivers are supplied to us by the same manufacturing facilities used by the big name vendors and then fully tested for the intended host system at our telecoms test lab before dispatch.

Below you will find a snapshot of the CFP optical transceivers that TXO Optics can offer at a fraction of the cost of OEM supply.
