1.25G Singlemode SFP Transceiver LC – 2km – 1310

Fast & Reliable Gigabit Fibre Performance – fibresales 1.25G Singlemode SFP Transceiver

The FibreSales 1.25G Singlemode SFP Transceiver (SFP1G-2) is built for high-speed, point-to-point fibre connections up to 2km. With a 1310nm wavelength and a 1.25Gbps data rate, it delivers fast, consistent performance for enterprise, campus, and access networks.

Whether you’re linking switches, expanding a backbone, or running fibre to the edge, this SFP offers low-loss, high-efficiency performance in a compact format.

Built to Industry Standards

This module supports the IEEE 802.3z (1000Base-LX) standard, ensuring reliable integration with compliant switches, routers, and converters. It also supports Digital Diagnostic Monitoring (DDM), giving you real-time visibility into temperature, optical power, and voltage levels.

Additionally, the duplex LC interface fits all standard SFP ports. It’s hot-swappable, meaning you can plug it in or pull it out without powering down your system—saving time during upgrades or maintenance.

Seamless Compatibility – fibresales 1.25G Singlemode SFP Transceiver

You can count on out-of-the-box compatibility with most major brands, including Cisco, HP, Ubiquiti, Mikrotik, and Juniper. If your system needs a specific firmware code, we offer fast in-house reprogramming to suit your setup perfectly.

Each unit is tested for optical performance, power budget, and signal integrity—so your link runs clean and stable from day one.

Low Power. High Value.

Despite its power, this transceiver is extremely efficient. It uses minimal energy and generates little heat, making it ideal for dense racks or extended use.

With local support, fast delivery, and a 3-year warranty, the SFP1G-2 offers unbeatable value. You don’t need to overpay for brand-name optics when FibreSales delivers the same quality—just smarter.
