## Summary description

The Extralink SFP WDM Module offers a data transfer rate of 1.25Gbps over a distance of 20km. It operates at wavelengths of 1310nm and 1550nm, making it suitable for single-mode fiber applications. The module features a metal housing for durability and operates at an input voltage of 3.3V. Weighing only 51g, it is compact and efficient, ideal for various networking needs.

## Long description

The Extralink SFP Module 1.25G 1310/1550nm 20km is a single-mode bidirectional transceiver designed for optical network links up to 20 km. Supporting a data rate of 1.25 Gbps and operating on 1310 nm and 1550 nm wavelengths, this SFP module is housed in a metal casing for mechanical stability and thermal dissipation. It is intended for use with single-mode fiber (SMF) networks and requires a 3.3 V input supply while remaining compact and lightweight for easy installation in compatible SFP ports.
Advantages
The module provides a straightforward plug-and-play solution for extending fiber connections without requiring complex configuration. Metal housing enhances durability and heat management, and the bidirectional WDM design reduces the need for paired fibers by allowing transmission and reception on different wavelengths. Compliance with laser safety Class I and RoHS ensures adherence to common safety and environmental standards.
Suitable for
 Gigabit Ethernet links over single-mode fiber
 Switch-to-switch fiber connections and backplane interfaces
 Router-to-server or server-to-storage optical links
 Optical transmission systems requiring up to 20 km reach
Key specifications
 Interface type: SFP (small form-factor pluggable)
 Data transfer rate: up to 1.25 Gbit/s
 Wavelengths: 1310 nm and 1550 nm (bidirectional WDM)
 Maximum transmission distance: up to 20 km over single-mode fiber
 Housing: metal case for improved durability and thermal performance
 Operating voltage: 3.3 V
 Weight: 0.051 kg
 Colour: silver
 Optical safety: Class I laser compliance
How to use
Insert the SFP module into a compatible SFP slot on your network device while the device is powered down or following the device vendor’s hot-swap guidelines. Connect single-mode fiber with the appropriate SC connectors, ensuring that transmit and receive wavelengths are paired correctly with the counterpart module (1310 nm ↔ 1550 nm). After physical installation, verify link status and interface configuration via the host device management tools and monitor optical levels to confirm reliable operation.
Usage recommendations
Use certified single-mode fiber (SMF) with proper SC connectors and maintain clean fiber endfaces to prevent signal degradation. For best results, ensure transceiver pairs are matched (one 1310 nm module with one 1550 nm module) and observe manufacturer guidelines for ESD protection and operating temperature ranges. Regularly check device and link diagnostics to detect potential issues early.
