CFP2-100G-ER4

The CFP2-100G-ER4 is a Cisco optical module in the CFP2 form factor, delivering 100 Gigabit Ethernet throughput and designed for extended-reach ER4 links. It leverages four distinct LAN-WDM wavelengths to achieve extended distances over single-mode fiber, typically up to 40 km, based on 100GBASE-ER4 technology.

This module is intended for operators and data centers deploying 100G interconnections over significant distances between remote sites. The multi-wavelength ER4 technology distinguishes it from short-reach SR4 or standard LR4 modules, positioning it for demanding metropolitan backbone applications.
