Description

Deliver ultra‑fast 100G Ethernet connectivity with the Cisco QSFP‑100Gb‑CWDM4‑S. This compact QSFP28 module supports up to 2 km reach over single‑mode fiber using duplex LC connectors. Operating on four CWDM wavelengths (1271, 1291, 1311, 1331 nm), it provides reliable, high‑density, and energy‑efficient performance for modern data centers and enterprise backbones. With low power consumption (~3.5 W), hot‑swappable design, and compliance with CWDM4 MSA and IEEE 802.3bm standards, it is the ideal choice for scalable short‑reach 100G deployments.
