Cisco CFP2-100G-ER4 100G ER4 CFP2 Transceiver – 40km SMF Reach
The Cisco CFP2-100G-ER4 is a high-performance 100 Gigabit Ethernet transceiver designed for long-haul and metro network applications. Built on the compact CFP2 form factor, this module supports 100GBASE-ER4 over single-mode fiber (SMF) with a maximum reach of up to 40 km. It delivers reliable, high-capacity connectivity for data center interconnect (DCI), service provider backbones, and enterprise core networks.
Featuring four LAN-WDM wavelengths and duplex LC optical connectors, the CFP2-100G-ER4 ensures line-rate 103.125 Gbps performance with ultra-low power consumption under 9W. It supports Forward Error Correction (FEC) at the host level for enhanced signal integrity and provides Digital Optical Monitoring (DOM) for real-time diagnostics.
The transceiver is fully compatible with Cisco NCS, ASR 9000, and Nexus platforms, and adheres to the CFP2 MSA standard, ensuring interoperability across a wide range of networking environments. With hot-swappable design, robust EMI/ESD compliance, and extended commercial temperature support (0°C to 70°C), it is optimized for carrier-grade deployments and high-density optical transport.
Upgrade your network with the Cisco CFP2-100G-ER4 for long-distance, high-capacity, and reliable 100G Ethernet connectivity.
