100G CFP
Overview: The 100G CFP (Common Form Factor Pluggable) Optical Transceivers are standardized high‑speed modules designed to deliver 100 Gbps aggregate bandwidth across ten 10 Gbps lanes or four 25 Gbps lanes depending on the variant. Defined under the CFP MSA (Multi‑Source Agreement), these modules support a wide range of optical interfaces such as CFP SR10, LR4, ER4 and ZR for data center and telecom applications.

FAQ – 100G CFP Optical Transceivers
1. What is a 100G CFP transceiver?
A 100G CFP transceiver is a high‑speed pluggable optical module supporting 100 Gbps data transfer for telecom and data center applications as defined by the CFP MSA.
2. What are the main types of CFP modules?
The three primary generations are CFP, CFP2, and CFP4—each smaller and more power‑efficient than the previous one while maintaining electrical and protocol compatibility.
3. What connector types are used in 100G CFP modules?
CFP SR10 versions use MTP/MPO‑24 connectors, whereas CFP LR4/ER4/ZR use standard duplex LC interfaces for single‑mode fiber connections.
4. What is the difference between CFP, CFP2, and CFP4?
CFP is the original form factor (~24 W), CFP2 is half the size (~16 W), and CFP4 is one‑quarter (~8 W), providing higher port density and better energy efficiency.
5. Is CFP interchangeable with QSFP modules?
No. CFP and QSFP form factors have different sizes and connector standards, so they are not mechanically compatible, though they support the same 100GBASE protocols.
6. What fiber type is required for 100G CFP LR4 modules?
CFP LR4 modules use single‑mode fiber (SMF) with LC connectors and operate at 1310 nm to achieve up to 10 km reach per IEEE 802.3ba 100GBASE‑LR4.
7. What is the typical power consumption of 100G CFP modules?
Power varies by generation: CFP uses up to 24 W, CFP2 around 16 W, and CFP4 below 8 W, depending on reach and optical components.
8. Which standards define CFP transceivers?
CFP modules follow IEEE 802.3ba for 100 Gigabit Ethernet and the CFP MSA for mechanical dimensions, electrical interfaces, and management protocols.
