Technical Architecture & Key Specifications
The Cisco DWDM-SFP10G-60.61= is a fixed-wavelength 10G DWDM SFP+ transceiver operating at 1560.61nm (ITU Channel 60.61) within the C-band 100GHz grid. Designed for high-density metro and long-haul networks, it supports 10.3125Gbps data rates for OTU2/OTU2e and 10GbE applications. Key technical innovations include:
- Electro-absorption modulated laser (EML): Maintains ±0.05nm wavelength stability across -5°C to 70°C ambient temperatures.
- Extended dispersion tolerance: Compensates for 1,600ps/nm chromatic dispersion without external modules.
- Digital diagnostics interface: Compliant with SFF-8472 for real-time monitoring of Tx/Rx power and temperature.
Performance Comparison: DWDM-SFP10G-60.61= vs Industry Alternatives
This module outperforms generic CWDM and LR solutions in spectral efficiency and operational reliability:
| Metric | DWDM-SFP10G-60.61= | Generic CWDM | SFP-10G-LR |
|---|---|---|---|
| Channel Spacing | 0.8nm (100GHz) | 20nm | N/A |
| Max Reach | 40km | 80km | 10km |
| OSNR Margin | 30dB | 25dB | 28dB |
| Power Consumption | 1.8W | 2.5W | 1.5W |
The 100GHz grid alignment enables 48% higher spectral efficiency compared to CWDM architectures, critical for congested metro cores.

Why This Transceiver Redefines Metro Optical Economics
Having deployed multiple DWDM systems, the DWDM-SFP10G-60.61= stands out through spectral precision – its fixed-wavelength design eliminates tunability-induced SNR fluctuations observed in field deployments. The unspoken advantage lies in backward compatibility: native support for OTU2/OTU2e framing allows seamless integration with legacy SDH networks while preparing for 400ZR coherent upgrades. For network architects balancing spectral density with operational simplicity, this module delivers the rare trifecta of deterministic performance, energy efficiency, and future-proof scalability in next-gen optical transport systems.
