## Summary description

Pair of Extralink SFP WDM fiber transceivers, 1.25 Gbit/s (1250 Mbps) each, designed for single‑mode links up to 3 km. Operate at 1310/1550 nm wavelengths with LC connectors and digital optical monitoring (DOM). SFP interface, FCC certified. Suitable for point‑to‑point fiber uplinks, CWDM/bi‑di applications and network equipment with SFP ports.

## Long description

Pair of Extralink SFP WDM fiber transceivers for single‑mode links, each supporting a 1.25 Gbit/s (1250 Mbps) data rate. The modules operate at 1310 nm and 1550 nm wavelengths and use LC connectors. Designed for point‑to‑point fiber uplinks and bi‑directional (WDM/bi‑di) applications, the pair supports single‑mode fiber connections up to 3 km and includes digital optical monitoring (DOM) for real‑time performance metrics. The transceivers use the SFP form factor and comply with SFP MSA and SFF‑8472 specifications. All optical components meet Class I laser safety requirements.
Advantages
The Extralink SFP WDM pair provides interoperable SFP compatibility and a compact LC connector interface, enabling straightforward installation into network equipment with SFP ports. With DOM support, the modules allow monitoring of optical power and transceiver status to aid diagnostics and maintenance. The modules are optimized for single‑mode links and bi‑directional WDM setups, reducing fiber cabling while maintaining a 1.25 Gbit/s throughput per module.
Suitable for
Point‑to‑point fiber uplinks between switches and routers
Bi‑directional (WDM) fiber links to save fiber strands
Gigabit Ethernet and server or router interfaces with SFP ports
Short‑distance single‑mode connections up to 3 km
Key specifications
Data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
Supported link distance: up to 3000 m over single‑mode fiber
Operating wavelengths: 1310 nm and 1550 nm (pair)
Connector type: LC duplex
Form factor: SFP (small form‑factor pluggable)
Digital optical monitoring (DOM) supported
Laser safety class: Class I
How to use
Install each transceiver into a compatible SFP slot on the network devices at both ends of the link, ensuring that the 1310 nm and 1550 nm modules are placed according to the required transmission direction for bi‑directional operation. Connect single‑mode LC fiber patch cords between the corresponding LC ports. Verify link status on the connected equipment and monitor optical parameters via the DOM feature if supported by the host device. Observe standard electrostatic discharge (ESD) precautions and do not look directly into the optical port.
Usage recommendations
For reliable performance, use single‑mode fiber with appropriate attenuation characteristics, keep LC connectors clean, and confirm device compatibility with SFP MSA and SFF‑8472. Use the DOM data to verify optical power levels and temperature during installation and troubleshooting. Avoid exceeding the specified 3 km link length for this product pair.
