100G CFP2 Transceivers Modules
Overview: The 100G CFP2 (Common Form Factor Pluggable 2) Optical Transceivers represent the second generation of CFP technology for 100 Gigabit Ethernet and OTN applications. Compared to the original CFP, the CFP2 form factor is half the width and depth, offering double port density and lower power consumption. These modules support various optical interfaces such as CFP2‑SR10, CFP2‑LR4, and CFP2‑ER4 for data center, metro, and long‑haul networks over single‑mode or multimode fiber infrastructure.

FAQ – 100G CFP2 Optical Transceivers
1. What is a 100G CFP2 transceiver?
A 100G CFP2 transceiver is a compact, hot‑pluggable optical module that supports 100 Gbps links for Ethernet and OTN applications, offering a smaller and more efficient design than the original CFP form factor.
2. How does CFP2 differ from CFP and CFP4?
CFP2 is half the width and depth of CFP, while CFP4 is half the size of CFP2. All support 100 GbE/OTU4 standards but vary in density and power requirements.
3. Which connector interfaces does CFP2 use?
CFP2 SR10 uses MTP/MPO‑24 connectors, while CFP2 LR4 and ER4 use duplex LC connectors for single‑mode fiber links.
4. What is the power consumption of 100G CFP2 modules?
Typical power consumption ranges from 10 W to 16 W depending on the model and optical reach, making it more efficient than the first‑generation CFP modules.
5. What are the main applications of CFP2 transceivers?
CFP2 transceivers are used in data center interconnects, metro and long‑haul backbones, OTN links, and high‑capacity switch uplinks.
6. Is 100G CFP2 interoperable with CFP modules?
Yes, CFP2 is electrically interoperable with CFP modules for 100 G protocols, but their mechanical interfaces and cages are different.
7. What are the common variants of 100G CFP2 modules?
The main variants are CFP2‑SR10 (short‑reach MMF), CFP2‑LR4 (10 km SMF), and CFP2‑ER4 (40 km SMF) modules defined by IEEE 802.3ba.
8. Which standards govern CFP2 optical transceivers?
CFP2 transceivers comply with IEEE 802.3ba 100GBASE‑SR10/LR4/ER4 and CFP2 MSA specifications, as well as ITU‑T G.959.1 and CEI‑28G VSR electrical standards.
