Overview of the Cisco CWDM-SFP-1510-25=
The Cisco CWDM-SFP-1510-25= is a Coarse Wavelength Division Multiplexing (CWDM) transceiver module designed for high-capacity, long-distance fiber optic communication. Operating at a 1510 nm wavelength with a 25 km reach, it enables cost-effective multiplexing of multiple data channels over a single fiber strand. This SFP (Small Form-Factor Pluggable) module is tailored for enterprises and service providers needing to optimize fiber infrastructure while supporting protocols like Ethernet, SONET, and Fibre Channel.
Technical Specifications and Key Features
The module’s design emphasizes simplicity, scalability, and interoperability. Here are its standout attributes:
- CWDM Technology: Leverages the 1510 nm wavelength to minimize interference and maximize bandwidth efficiency.
- 25 km Reach: Supports up to 25 kilometers of single-mode fiber (SMF) without signal degradation.
- Multi-Protocol Support: Compatible with 1 Gbps Ethernet, 1G/2G/4G Fibre Channel, and SONET/SDH standards.
- Hot-Swappable: Enables live insertion/removal without disrupting network operations.
- Digital Diagnostics Monitoring (DDM): Provides real-time insights into temperature, voltage, and optical power levels via SNMP or CLI.
Addressing Common Deployment Questions
Q: Which Cisco devices support the CWDM-SFP-1510-25=?
The module is compatible with Catalyst 3560/3750/4500/6500 switches, ASR 9000 routers, and other platforms supporting Cisco CWDM SFPs. Always verify IOS compatibility before deployment.
Q: How does CWDM differ from DWDM?
CWDM uses 20 nm channel spacing (vs. 0.8 nm for DWDM) and operates in the 1270–1610 nm range. While DWDM offers higher density, CWDM is more cost-effective for shorter distances.
Q: Can this module handle 10 Gbps speeds?
No—it’s designed for 1 Gbps applications. For 10G, consider Cisco’s CWDM-XFP or DWDM-SFP+ modules.
Ideal Use Cases
1. Metro-Area Network (MAN) Extensions
The 25 km reach makes the CWDM-SFP-1510-25= ideal for connecting urban data centers or office branches without costly fiber trenching.
2. Enterprise Campus Backbones
By multiplexing multiple 1G channels over a single fiber pair, it reduces cabling complexity in large campuses.
3. Service Provider Aggregation
Telecom operators use CWDM modules like this to aggregate traffic from cell towers or residential gateways into central hubs.
Performance Comparison: Cisco CWDM-SFP-1510-25= vs. DWDM-SFP-1550-80
| Feature | CWDM-SFP-1510-25= | DWDM-SFP-1550-80 |
|---|---|---|
| Wavelength | 1510 nm (fixed) | Tunable (C-band) |
| Max Reach | 25 km | 80 km |
| Channel Spacing | 20 nm | 0.8 nm |
| Max Speed | 1 Gbps | 10 Gbps |
| Cost | $$ | $$$$ |
The CWDM-SFP-1510-25= suits budget-conscious deployments under 25 km, while DWDM modules cater to high-speed, long-haul needs.

Final Assessment
Having deployed similar CWDM modules in metro and campus environments, the Cisco CWDM-SFP-1510-25= strikes a practical balance between cost and performance. Its simplicity and interoperability make it a workhorse for enterprises scaling fiber backbones without overhauling infrastructure. However, organizations anticipating future 10G upgrades should evaluate hybrid CWDM/DWDM strategies early. For sub-25 km, 1G use cases, this module remains a reliable, budget-friendly choice—especially when paired with Cisco’s ecosystem for seamless management.
