The Cisco CPAK-100G-CWDM4 is a 100 Gbps transceiver designed for short-range data transmission over single-mode fiber (SMF). It uses CWDM wavelengths, operating at 1271 nm, 1291 nm, 1311 nm, and 1331 nm.
The device features the compact CPAK form factor and supports Duplex LC connectors for high-speed connectivity in optical networks. Its range capabilities allow it to transmit up to a distance of two kilometers on SMF cables while maintaining signal integrity through efficient wavelength division multiplexing. This module adheres to rigorous IEEE standards for BASE-CWDM4 implementations within enterprise or telecom applications requiring reliable bandwidth performance across limited distances using minimal cabling complexity.
