## Summary description

Lightwin LWO-SFP-LX-10-I is an industrial-grade SFP transceiver supporting 1.25 Gbit optical links over singlemode fiber at 1310 nm. Designed for up to 10 km reach, it features LC-duplex connector and DDM (Digital Diagnostic Monitoring) for real-time status. Suited for switches, routers and industrial network equipment requiring reliable long-distance 1G fiber connectivity.

## Long description

Lightwin LWO-SFP-LX-10-I is an industrial-grade SFP transceiver module that provides 1.25 Gbit/s optical connectivity over singlemode fiber at a wavelength of 1310 nm. The module is specified for links up to 10 km, uses an LC-duplex connector and supports Digital Diagnostic Monitoring (DDM) for real-time monitoring of optical power, temperature and other operating parameters. The compact SFP form factor makes it compatible with many switches, routers and industrial network devices that accept hot-swappable SFP modules.
Advantages
This transceiver offers stable 1 Gbit optical links with a 10 km reach on singlemode fiber and a standardized LC-duplex interface for straightforward installation. Industrial-grade design and DDM support enable continuous status monitoring and increased reliability in demanding environments. The SFP form factor allows hot-swap replacement and easy integration into equipment that supports small form-factor pluggable modules.
Suitable for
 Connecting switches and routers over singlemode fiber for 1 Gbit links
 Industrial Ethernet deployments requiring ruggedized optics
 Longer-distance backbone connections within campuses or between buildings (up to 10 km)
 Network equipment that supports hot-swappable SFP modules with LC-duplex ports
When it may not be suitable
This module is designed for singlemode fiber at 1310 nm and is not appropriate for multimode fiber links; using it with incompatible fiber types will cause link failure or degraded performance. It is also limited to 1.25 Gbit/s operation, so it will not provide higher-speed interfaces such as 10 Gbit/s or more.
Key specifications
 Data rate: 1.25 Gbit/s
 Wavelength: 1310 nm
 Maximum reach: up to 10 km on singlemode fiber
 Connector type: LC-duplex
 Form factor: SFP (small form-factor pluggable)
 Monitoring: Digital Diagnostic Monitoring (DDM)
 Operating class: industrial temperature range (industrial-grade)
How to use
Insert the Lightwin SFP module into a compatible SFP port on a switch, router or industrial media converter while the host device is powered off or hot-swap if the host supports it. Connect the LC-duplex singlemode fiber patch cable ensuring transmit and receive fibers are correctly crossed. After insertion the host should detect the module and establish a 1.25 Gbit link; use the host management interface and DDM readings to verify optical power, temperature and other diagnostics. Follow the equipment vendor’s procedures for firmware, port configuration and link testing.
What to consider before purchase
 Ensure your equipment accepts SFP transceivers and supports the required data rate
 Confirm you are using singlemode fiber compatible with 1310 nm optics
 Verify required link distance does not exceed 10 km
 Check the industrial temperature range is necessary for your installation
Usage recommendations
Use certified singlemode LC-duplex patch cords, maintain correct fiber polarity, and monitor DDM values after installation to ensure stable operation. For installations near the maximum reach, test optical power margins and consider using higher-grade fibers or repeaters if margins are insufficient.
