## Summary description

The Extralink SFP WDM Module offers a data transfer rate of 1.25Gbps over a distance of up to 80km. It operates at wavelengths of 1490/1550nm and features an LC connector. This single-mode fiber optic transceiver is designed for reliable long-distance communication.

## Long description

The Extralink SFP 1.25G 1490/1550nm 80km LC DOM is a single-mode WDM fiber optic transceiver designed for long-distance data links. Supporting a data rate of 1.25 Gbps and a reach of up to 80 km, the module uses LC connectors and WDM wavelengths of 1490 nm and 1550 nm to enable simultaneous bidirectional transmission over a single fiber. The transceiver conforms to the Small Form-Factor Pluggable (SFP) mechanical standard and integrates transmitter and receiver components optimized for reliable optical networking.
Advantages
The module provides stable long-reach transmission at 1.25 Gb/s while minimizing fiber usage through wavelength division multiplexing. Its single-mode design and LC interface ensure compatibility with common telecom and enterprise fiber equipment. The transceiver includes integrated laser control, receiver amplification and monitoring capabilities for consistent performance over extended distances. Hot-pluggable SFP form factor allows insertion and replacement without powering down the host device.
Suitable for
 Long-distance point-to-point fiber links in metropolitan and access networks
 Fiber connections between switches, routers and optical line terminals
 Single-fiber bidirectional links using WDM to reduce fiber count
 Upgrading or extending existing single-mode optical networks
Key specifications
 Data rate: 1.25 Gbps
 Wavelengths: 1490 nm (Tx) / 1550 nm (Rx) or vice versa depending on module orientation
 Maximum reach: up to 80 km over single-mode fiber
 Connector type: LC duplex (single-fiber WDM usage)
 Transceiver type: SFP (Small Form-Factor Pluggable), hot-pluggable
 Monitoring: digital optical monitoring / DDM/DOM support for diagnostic parameters
 Laser type: DFB (distributed feedback) transmitter with LD control
How to use
Insert the SFP module into an available SFP slot of a compatible switch, router or optical device, ensuring proper orientation until it clicks into place. Connect the LC-terminated single-mode fiber using the appropriate WDM pairing so that the transmit wavelength of one end matches the receive wavelength of the other end. Verify link status via device indicators or the module's digital monitoring output. Replace modules with the system powered on if required; follow manufacturer guidance for hot-pluggable transceivers.
Usage recommendations
For reliable links at maximum distance, use ITU-T-compliant single-mode fiber with appropriate attenuation characteristics and ensure connectors and splices are clean. Match complementary WDM modules at each link end (1490/1550 pairing) and monitor optical power and temperature via DOM to detect degradation early.
