1.25G SFP LX 1310nm 20KM LC optical transceiver is a high-performance module designed for extended long-reach communication links. It operates at a wavelength of 1310nm and supports data rates of up to 1.25 Gbps, making it ideal for Gigabit Ethernet applications.
This transceiver achieves a significantly extended transmission distance of up to 20 kilometers over standard 9/125µm single-mode fiber (SMF), facilitating connections between geographically dispersed network nodes.
Featuring a hot-pluggable SFP form factor and a duplex LC connector, it ensures easy installation and broad compatibility with a wide range of networking equipment. This module provides a reliable and cost-effective solution for building robust metropolitan area network (MAN) access or campus backbone links.
