Extralink Fiber Optic SFP Module 1.25Gbps LC/UPC 1550nm 80km Single Mode DOM

The Extralink Fiber Optic SFP Module 1.25Gbps LC/UPC 1550nm 80km Single Mode DOM is a reliable transceiver designed for high-speed data transmission over long distances. Operating with single-mode fiber infrastructure, this module supports data transfer rates up to 1250 Mbit/s and reaches distances of up to 80 km. Equipped with a DFB laser operating at a 1550 nm wavelength and a PIN photodetector, it ensures stable and efficient optical communication. The unit features an LC/UPC duplex interface and includes Digital Diagnostics Monitoring support for real-time performance tracking.

Advantages

This SFP transceiver provides significant reach capabilities, allowing reliable data links across spans of up to 80 kilometers without signal degradation. Compliance with SFP MSA and SFF-8472 standards ensures broad compatibility with standard networking hardware. The integrated Digital Diagnostics Monitoring functionality allows administrators to monitor critical parameters such as optical power, temperature, and voltage dynamically. Built with a standard SFP form factor and operating on a single 3.3V power supply, it integrates smoothly into existing network switches and routers.

Suitable for

• Long-distance enterprise networking infrastructure
• High-speed telecommunications backbones
• Connecting remote buildings or network nodes up to 80 km apart
• Fiber optic links requiring real-time diagnostic monitoring

When it may not be suitable

This transceiver is not designed for multi-mode fiber optic cabling setups and will not function correctly if paired with multi-mode fiber types. Additionally, applications requiring shorter transmission ranges may benefit from lower-cost short-range optics rather than an 80 km single-mode module.

Key specifications

• Data transfer rate up to 1250 Mbit/s
• Wavelength of 1550 nm
• Maximum transmission distance of 80 km
• Single-mode fiber compatibility
• LC/UPC duplex interface type
• Standard SFP form factor
• Digital Diagnostics Monitoring support
• Input voltage range of 3.13 to 3.47 V

How to use

To install the transceiver, ensure the networking device is powered off or supports hot-swapping according to manufacturer guidelines. Gently insert the SFP module into the available SFP slot until it clicks securely into place. Connect the single-mode fiber optic patch cable with an LC/UPC connector into the duplex interface of the module. Once connected, verify the link status and optical parameters through the network switch management interface using the Digital Diagnostics Monitoring data.

What to consider before purchase

• Verify that your network switch or router features an available SFP slot and supports 1.25G transceivers
• Confirm that your cabling infrastructure consists of single-mode fiber optic lines
• Check the required transmission distance to ensure an 80 km module matches your network topology

Usage recommendations: Handle the optical transceiver with ESD protection measures and keep dust caps installed on the optical bore until the fiber patch cable is ready to be connected to prevent contamination.
