Cisco QSFP-100G-CWDM4-S= Module 100Gbps CWDM4 , 2km Reach , Low
Power Cisco Module
The Cisco QSFP-100G-CWDM4-S= is a high-performance 100Gbps QSFP28
optical transceiver designed for data center interconnects (DCI),
enterprise networks, and cloud infrastructure. Compliant with CWDM4
MSA standards, it delivers reliable 100G Ethernet (4×25Gbps)
transmission over single-mode fiber (SMF) with a 2km reach, making
it ideal for high-bandwidth applications.
Key Features & Benefits
✔ 100Gbps High-Speed Data Transfer – Supports 100G Ethernet,
ensuring ultra-fast connectivity for modern networks.
✔ CWDM4 Wavelength Technology – Uses four wavelengths (1271nm,
1291nm, 1311nm, 1331nm) over dual-fiber SMF, reducing cabling
complexity.
✔ Low Power Consumption (<3.5W) – Energy-efficient design helps
lower operational costs in data centers.
✔ 2km Reach on Single-Mode Fiber – Ideal for DCI, campus networks,
and metro applications.
✔ Digital Diagnostics Monitoring (DDM/DOM) – Real-time monitoring
of temperature, voltage, and optical power for proactive
maintenance.
✔ Hot-Swappable & MSA-Compliant – Ensures compatibility with Cisco
Nexus 9000, ASR routers, and third-party switches.
