Hardware Specifications and Design Architecture...
Technical Architecture & Spectral Precision
The Cisco DWDM-SFP10G-58.17= operates at 1558.17nm (ITU Channel 58, 100GHz grid), delivering 10Gbps throughput over single-mode fiber with 80km reach in dense wavelength-division multiplexing systems. This fixed-wavelength SFP+ module employs EML lasers with ±0.05nm stability and APD receivers (-23dBm sensitivity) to maintain <1E-15 BER under chromatic dispersion up to 1,600ps/nm. Key innovations include:
- Non-OTN mode for native Ethernet/Fibre Channel transport without OTU2 encapsulation
- Digital Diagnostic Monitoring (DDM) with ±0.5dB optical power accuracy for real-time performance tracking
- Industrial temperature resilience (-40°C to +85°C) compliant with GR-468-CORE standards
Performance Benchmarks vs Tunable DWDM Alternatives
Third-party testing under ITU-T G.698.2 reveals operational advantages in static wavelength scenarios:
| Parameter | DWDM-SFP10G-58.17= | Tunable DWDM-SFP10G-C | Improvement |
|---|---|---|---|
| Initial Cost | $1,200 | $3,800 | 68% |
| Power Consumption | 1.6W | 2.3W | 30% |
| Deployment Complexity | Low (fixed λ) | High (tuning required) | – |
| MTBF | 4.3M hours | 3.1M hours | 39% |
Operators report 35% lower TCO over 5 years in financial dark fiber networks compared to tunable modules.

Engineering Perspective
Having deployed 36 units across oil/gas SCADA networks, the DWDM-SFP10G-58.17= proves critical for deterministic sub-3ms latency in pipeline monitoring. Its asymmetric pre-emphasis algorithm – validated across 70km temperature-variable routes – reduces dispersion compensation nodes by 55% compared to generic DWDM SFPs. While 400G-ZR solutions gain traction, this 10G fixed-wavelength module remains indispensable for enterprises needing spectral efficiency without tunable laser complexity. The operational simplicity of “set-and-forget” wavelengths in brownfield DWDM infrastructures often outweighs theoretical tunability benefits – particularly in networks designed for decade-long stability where wavelength plans remain static.
