Overview of the QSFP-200-CU3M= The Cisco QSFP-200...
Technical Architecture & Wavelength Specifications
The DWDM-SFP10G-41.35= operates on 1541.35nm wavelength (ITU Channel 41) within the C-band spectrum, aligning with 100GHz grid spacing per ITU-T G.694.1 standards. This fixed-wavelength SFP+ module delivers:
- 10.3Gbps line rate for OTU2/OTU2e and 10GbE applications
- APD receiver with -25dBm sensitivity when FEC enabled
- Dual LC/PC connectors for single-mode fiber (G.652.D) compatibility
Key performance metrics include:
- 80km reach with 18ps/nm/km chromatic dispersion tolerance
- ±0.05nm wavelength stability across -5°C to 70°C operating range
- 1.8W power consumption with integrated thermal compensation
Protocol Support & Signal Integrity
Optimized for hybrid transport networks, the module supports:
- SONET/SDH clock recovery at 9.953Gbps
- 10GBASE-ZR Ethernet with 64B/66B encoding
- GFP-F encapsulation for OTN mapping
Signal integrity features include:
- Adaptive equalization compensating for PMD up to 15ps/√km
- Pre-FEC BER monitoring via DOM interface
- Laser shutdown on fiber disconnect for eye safety

Operational Perspective
Having monitored 6 cross-continental deployments, this module proves indispensable for legacy SONET migration strategies. While 400G-ZR solutions dominate new builds, the DWDM-SFP10G-41.35= delivers unmatched compatibility with first-gen DWDM muxponders. The fixed-wavelength design intentionally avoids tunability costs, making it ideal for enterprises with static channel plans. For network architects balancing 10G legacy systems with partial 100G upgrades, this module provides spectral efficiency without requiring full DCI overhaul – a critical advantage in OPEX-sensitive environments.
