Specifications
Cisco QDD-2X100-CWDM4-S 2x100GBASE-CWDM4 QSFP-DD Transceiver Module 1271-1331nm 2km SMF Dual CS Connector 10-3424-01
The Cisco QDD-2X100-CWDM4-S is a high-density, hot-swappable dual-channel 100G (200G aggregate bandwidth) QSFP-DD optical transceiver. It is purpose-built for next-generation hyperscale data centers, cloud networking, and enterprise core infrastructures. By packing two independent 100GBASE-CWDM4 interfaces into a single QSFP-DD form factor, it allows network operators to double their 100G port density without expanding physical rack space. Utilizing dual Duplex CS connectors, this module supports links of up to 2 km over standard Single-Mode Fiber (SMF) using coarse wavelength-division multiplexing (CWDM) technology.

Product Highlights

1.Dual-Rate Flexibility for 100G/200G Networks
  • Supports both 2x 100G independent channels and aggregated 200Gbps operation. This exceptional dual-rate versatility makes it highly adaptable for mixed-rate network deployments and ensures seamless future bandwidth upgrades.

2.Compact Duplex CS Connector for Ultra-High Density

  • Features a Duplex CS interface with a significantly smaller footprint than traditional LC connectors. This enables higher port counts on switch front panels, perfectly supporting the strict high-density requirements of modern data centers.

3.Cost-Effective CWDM4 Technology Without Coherent Complexity

  • By utilizing four CWDM wavelengths (1271nm-1331nm) on a single fiber pair, it delivers full 200G performance without the operational complexity and high cost of coherent optics. It leverages existing single-mode fiber (SMF) infrastructure for highly cost-effective short-to-medium reach connectivity up to 2 km.

4.Compact QSFP-DD Form Factor with Optimized Power Efficiency

  • The QSFP-DD form factor supports massive port density in modern data center switches, enabling efficient scaling of 200G uplinks without consuming excessive rack space. Engineered with low-power semiconductor technology, it helps lower cooling costs and total cost of ownership (TCO).

5.Genuine Cisco Quality & Comprehensive Digital Optical Monitoring (DOM)

  • Featuring Cisco Part Number 10-3424-01, this module ensures seamless plug-and-play integration and native platform recognition. The integrated DOM capability allows network administrators to monitor real-time Tx/Rx optical power, temperature, and supply voltage for proactive maintenance.
