Overview of the Cisco CWDM-SFP10G-1570=
The Cisco CWDM-SFP10G-1570= is a 10 Gigabit Coarse Wavelength Division Multiplexing (CWDM) transceiver module engineered for high-capacity fiber optic networks. Operating at a 1570 nm wavelength, it enables cost-effective multiplexing of multiple 10G channels over a single fiber pair, extending reach up to 80 km with minimal signal loss. Designed for service providers and enterprises, this SFP+ module supports dense data center interconnects (DCI), metro-area networks (MAN), and high-speed enterprise backbones.
Key Technical Specifications
The CWDM-SFP10G-1570= combines performance with simplicity. Critical features include:
- 10Gbps Throughput: Compliant with 10G Ethernet, 10G Fibre Channel, and OTU-2 standards.
- 1570 nm Wavelength: Part of the standardized CWDM grid (18 channels between 1270–1610 nm).
- Extended Reach: Supports up to 80 km on single-mode fiber (SMF) with DFB laser technology.
- Digital Diagnostics Monitoring (DDM): Real-time tracking of temperature, Tx/Rx power, and voltage via SNMP or CLI.
- Low Power Consumption: Draws <1.5W, reducing operational costs in high-density deployments.
Addressing Common User Concerns
Q: Which Cisco platforms support this module?
The CWDM-SFP10G-1570= is compatible with Catalyst 3560-X, 3750-X, 4500-E, 6500-E switches, ASR 9000 routers, and Nexus 7000/7700 series. Verify IOS/IOS-XE compatibility using Cisco’s Transceiver Matrix.
Q: How does CWDM differ from DWDM at 10G?
CWDM uses 20 nm channel spacing (vs. 0.8 nm for DWDM), reducing the need for precision optics and temperature control. While DWDM supports 100+ channels, CWDM is more cost-effective for networks requiring ≤18 channels.
Q: Can it handle 25G or 40G speeds?
No—this module is optimized for 10G applications. For higher speeds, consider Cisco’s DWDM-QSFP28 or CFP2 modules.
Ideal Use Cases
1. Metro-Area Network (MAN) Expansion
The 80 km reach allows telecom providers to interconnect urban data centers or cellular hubs without costly amplifiers.
2. Enterprise Campus Backbones
By multiplexing multiple 10G streams over a single fiber pair, enterprises reduce cabling complexity and costs in large campuses.
3. Cloud Service Provider DCI
Cloud operators leverage CWDM to aggregate traffic between availability zones, maintaining low latency and high redundancy.
Performance Comparison: CWDM-SFP10G-1570= vs. DWDM-SFP-1550-100
| Feature | CWDM-SFP10G-1570= | DWDM-SFP-1550-100 |
|---|---|---|
| Max Speed | 10 Gbps | 10 Gbps |
| Wavelength Flexibility | Fixed (1570 nm) | Tunable (C-band) |
| Max Reach | 80 km | 100 km |
| Channel Density | 18 channels | 96+ channels |
| Cost per Channel | $ | $$$ |
The CWDM-SFP10G-1570= is ideal for budget-driven 10G deployments under 80 km, whereas DWDM suits high-density, long-haul scenarios.

Final Perspective
Having worked with CWDM solutions in metro networks, the Cisco CWDM-SFP10G-1570= stands out for its balance of affordability, simplicity, and reliability. Its extended reach and low power draw make it a pragmatic choice for enterprises and providers scaling 10G infrastructure without overinvesting in DWDM’s complexity. However, organizations anticipating future 100G+ needs should evaluate hybrid architectures early. For current 10G use cases, this module delivers consistent ROI—especially when integrated with Cisco’s ecosystem for end-to-end management.
