## Summary description

Lightwin 1.25 Gbit SFP singlemode fiber transceiver operating at 1310 nm for up to 10 km link distance. Supports 1.25 Gbit/s (1250 Mbit/s) data rate, LC-Duplex interface and DDM for diagnostic monitoring. Designed for fiber network uplinks and switches, compatible with SFP ports, requires 3.3 V power and is RoHS compliant with a 3-year warranty.

## Long description

The Lightwin 1.25 Gbit SFP fiber transceiver is a compact module for singlemode fiber links operating at 1310 nm, designed for link distances up to 10 km. It supports a 1.25 Gbit/s data rate and uses an LC‑duplex optical interface with digital diagnostic monitoring (DDM). The module is intended for use in network uplinks, switches and other equipment with SFP ports and requires a single 3.3 V power supply.
Advantages
This SFP transceiver offers a small form factor with LC connector compatibility and low electromagnetic emissions. It integrates an FP laser and PIN photodetector to provide reliable optical transmission at 1310 nm, and includes DDM for real‑time monitoring of optical parameters. The module complies with laser safety and RoHS standards and features signal ground isolation to the case for improved system safety.
Suitable for
Fiber uplinks between switches and routers over singlemode fiber
Connections requiring up to 10 km reach
Environments needing digital diagnostic monitoring (DDM) for optical parameters
Systems with SFP ports and LC‑duplex connectors
When it may not be suitable
This transceiver is not intended for multimode fiber networks or links that require wavelengths other than 1310 nm. It is designed for 1.25 Gbit/s operation; environments requiring higher Ethernet speeds (for example 10 Gbit/s) will need a different module. Also, use in installations exceeding 10 km requires transceivers with longer reach specifications.
Key specifications
Data rate: 1.25 Gbit/s (1250 Mbit/s)
Optical wavelength: 1310 nm
Maximum reach: up to 10 km on singlemode fiber
Optical interface: LC‑duplex
Transmitter type: FP laser
Receiver type: PIN photodetector
Power supply: single +3.3 V
Electrical interface: LVPECL compatible input/output
Digital diagnostics: DDM (SFF‑8472 compliant)
Standards: IEC‑60825 laser safety compliant; RoHS compliant
How to use
Insert the SFP transceiver into a compatible SFP port on a switch, router or media converter, ensuring the module seats fully and the device recognizes it. Connect LC‑duplex singlemode fiber patch cords to the transmit and receive ports, observing correct polarity. Power the host device with the standard 3.3 V supply; the module operates with typical SFP power-up procedures. Use the DDM interface to monitor optical power, temperature and diagnostic parameters through the host management software if supported.
What to consider before purchase
Confirm your equipment supports 1.25 Gbit/s SFP modules and LC‑duplex connectors
Verify singlemode fiber and correct polarity in your fiber runs
Ensure 10 km reach meets your link distance requirements
Check host compatibility with DDM/SFF‑8472 if diagnostic monitoring is required
Usage recommendations
For reliable operation, install the transceiver in a clean environment, use singlemode LC patch cords with correct polarity, and monitor DDM readings during deployment to confirm optical levels and temperature remain within expected ranges.
