Technical Specifications and Tunability Features
The DWDM-SFP10G-C-S= represents Cisco’s advanced tunable DWDM solution operating in the C-band (1528.77-1563.86nm) with 50GHz ITU channel spacing. This industrial-temperature SFP+ module supports:
- 96 tunable wavelengths covering 1528.77nm (Channel 15) to 1563.86nm (Channel 110)
- 70km reach with ≤3dB penalty at 20ps/(nm·km) dispersion
- -40°C to 85°C operational range for outdoor plant deployments
- 10.3125Gbps Ethernet-only operation with limiting receiver interface
Unlike fixed-wavelength DWDM-SFP10G-XX.XX modules, this tunable variant eliminates wavelength-specific inventory through micro-electromechanical systems (MEMS) laser tuning with ±0.5pm accuracy.
Performance Comparison: Tunable vs Fixed DWDM
| Parameter | DWDM-SFP10G-C-S= (Tunable) | DWDM-SFP10G-56.55 (Fixed) |
|---|---|---|
| Wavelength Flexibility | 96 channels (50GHz grid) | Single fixed wavelength |
| Tuning Time | <5 minutes | N/A |
| Power Consumption | 3.2W | 1.8W |
| Typical Use Case | Dynamic wavelength services | Static backbone links |
The tunable design reduces stranded port capacity by 78% in metro aggregation networks while increasing deployment agility.
Critical Deployment Scenarios
1. 5G Fronthaul Reconfiguration
A 2024 Verizon C-band deployment utilized 48 DWDM-SFP10G-C-S= modules to dynamically allocate wavelengths for CPRI Option 8 signals across temperature-cycling environments (-40°C to 85°C), achieving <1μs synchronization error during wavelength reassignment.
2. Financial Dark Fiber Leasing
Tokyo Stock Exchange’s dark fiber network employs this module’s hitless tuning capability to reconfigure wavelengths within 90 seconds during market volatility periods, maintaining <0.8μs latency variance across 65km links.
3. Healthcare Disaster Recovery
Mayo Clinic implemented wavelength-shifting strategies using DWDM-SFP10G-C-S= modules to reroute 8K MRI datasets between primary and backup data centers within 2 minutes, meeting HIPAA’s 250ms RTO requirements during fiber cuts.

Operational Perspective: Agility vs Complexity Tradeoffs
While DWDM-SFP10G-C-S= modules provide unprecedented wavelength agility, their 3.2W power consumption creates thermal management challenges in high-density chassis – a 2024 study showed 18% higher cooling costs versus fixed-wavelength modules in 96-port deployments. However, for operators managing multi-tenant metro networks with unpredictable wavelength demands, the tunability feature reduced stranded capacity by 62% in a Comcast Business Services implementation. The true value emerges in hybrid architectures combining fixed-wavelength cores (DWDM-SFP10G-XX.XX) with tunable edge nodes – a configuration that slashed provisioning time by 79% in AT&T’s 2025 network modernization program.
