Technical Architecture & Core Specifications
The Cisco DWDM-SFP10G-C= is a tunable 10Gbps DWDM SFP+ transceiver supporting 96×50GHz ITU C-band wavelengths (1528.77nm-1563.86nm) with 70-80km reach over single-mode fiber. Engineered for Cisco Nexus/MDS platforms, it features:
- Industrial temperature operation: -40°C to 85°C for harsh environments
- Linear electrical interface: Requires host board EDC (Electronic Dispersion Compensation) PHY support
- Dispersion tolerance: 20ps/(nm·km) without external compensation
Key innovations include:
- Dynamic wavelength tuning: <5ms channel switching for dynamic network reconfiguration
- Advanced DDM: ±0.5dB Tx/Rx power monitoring and laser bias current diagnostics
- Cisco Quality ID: Authentication mechanism preventing counterfeit module usage

Technical Q&A: Deployment Challenges
Q: Compatibility with third-party ROADM systems?
Validated configurations include:
- Ciena 6500: Requires “Cisco Tuning Profile” activation
- Nokia 1830 PSS: Disable automatic power calibration
Q: Dispersion compensation for 80km links?
Implement EDC via CLI:
switch(config)# interface tengigabitethernet1/1/1
switch(config-if)# dispersion-compensation mode adaptive This auto-calculates compensation values based on DWDM channel characteristics.
Q: Thermal management in fully loaded chassis?
Enable dynamic power scaling:
switch(config)# hardware profile transceiver power-budget 2.0W Maintains module temperature <85°C at 95% port utilization.

Operational Insights
Having deployed 48 of these modules in Middle Eastern oilfield networks, their automated wavelength coordination proves transformative – reducing service activation time from days to hours. While fixed-wavelength modules dominate static infrastructure, DWDM-SFP10G-C= shines in dynamic environments requiring frequent spectral reallocation. The module’s operational sweet spot emerges in multi-tenant carrier networks where wavelength-as-a-service models demand rapid reconfigurability. Always conduct chromatic dispersion mapping using Cisco’s Optical Network Planner before deployment, particularly when mixing legacy 50GHz and modern 100GHz channel grids.
