Cisco CPAK 100GBASE-ER4 Lite Module - For Optical Network, Data Networking - 1 x SC/PC Duplex 100GBase-ER4 Network - Optical Fiber - Single-mode - 100 Gigabit Ethernet - 100GBase-ER4 - Hot-swappable

The primary application of the Cisco CPAK 100GBASE-ER4 Lite module is to support 100-Gbps optical links over standard single-mode fiber (SMF, G.652) terminated with SC connectors. Nominal power consumption is less than 7.5W.

The ER4 Lite module is compatible with the 100GBASE-ER4 standard and supports link lengths up to about 25 km over standard SMF, G.652. It delivers an aggregate data signal of 100 Gbps, carried over four LAN wavelength-division multiplexing (WDM) wavelengths operating at a nominal 25 Gbps per lane. The module can be used over longer distances in engineered links with CPAK-100G-ER4L modules at both ends. Optical multiplexing and demultiplexing of the four wavelengths are managed within the module.
