## Summary description

The Lightwin LSFP-WDM-LA20-UNI is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. Operating at a wavelength of 1490 nm, it ensures reliable data transmission over fiber optic networks. This module is designed for easy integration and is suitable for various networking applications, providing high performance and stability.

## Long description

The Lightwin LSFP-WDM-LA20-UNI is a single‑fiber SFP transceiver module designed for use in fiber optic networks. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a transmitting wavelength of 1490 nm. The module uses an LC connector and is intended for point‑to‑point links over single‑mode fiber, offering reach up to 20,000 meters under compatible network conditions. The compact SFP form factor enables straightforward integration into switches, routers and media converters that accept SFP modules.
Advantages
This transceiver provides stable 1.25 Gbps performance over long distances with low power consumption and a compact SFP footprint. The single‑fiber WDM design reduces cabling requirements by allowing transmit and receive signals on a single fiber pair, and the LC connector ensures wide compatibility with standard fiber patch panels and pigtails. The module is engineered for easy hot‑swap installation and reliable operation in network equipment that supports standard SFP optics.
Suitable for
Long‑reach single‑mode fiber links between network switches or routers
Fiber uplinks for media converters and access devices
FTTx and ISP subscriber links requiring 1490 nm transmit wavelength
Environments where compact SFP optics and LC connectors are required
Key specifications
Maximum data transfer rate: 1250 Mbit/s
Operating (transmit) wavelength: 1490 nm
Maximum transfer distance: up to 20,000 m (single‑mode fiber)
Connector type: LC
Form factor: SFP (small form‑factor pluggable)
How to use
Insert the module into an SFP slot on a compatible switch, router or media converter while the device is powered on or following the host vendor's hot‑swap guidance. Connect a single‑mode fiber with LC connectors to the module, ensuring correct orientation of transmit and receive fibers according to the link plan. Configure the host device interfaces as required for 1.25 Gbps operation and verify link status using the network equipment's management interface or LED indicators. Follow standard fiber handling procedures to avoid bending losses and contamination of connector end faces.
Usage recommendations
Use this module with single‑mode fiber and LC patch cables rated for long‑reach links. Keep connector end faces clean and inspect with a fiber microscope before insertion. Ensure host equipment supports SFP optics at 1490 nm and 1.25 Gbps; check vendor compatibility lists if necessary. Store spare modules in anti‑static packaging and avoid exposure to extreme temperatures or humidity.
