## Long description

Lightwin LWO-SFP-85-SX is an SFP fiber optic transceiver module designed for 1.25 Gigabit Ethernet links. It uses 850 nm multimode optics with an LC duplex connector and supports data rates up to 1250 Mbit/s over distances up to 550 m. The module is intended for 3.3 V SFP ports and is supplied in a pack of 20 units for bulk deployments and equipment upgrades.
Advantages
The transceiver provides reliable multimode fiber connectivity for short-range Ethernet links, with a standard LC duplex interface for easy installation. Its support for 1.25 Gbit/s data rates and a transmission range up to 550 m makes it suitable for typical campus, data center spine-to-leaf, and enterprise wiring. The module is RoHS compliant and offers diagnostic monitoring (DDM) support for link status and performance checks.
Suitable for
Upgrading switches and routers to 1.25 Gbit/s SFP ports
Short-range multimode fiber links within buildings or across a campus (up to 550 m)
Data center links between top-of-rack and aggregation switches
Bulk installations and replacements (pack of 20)
When it may not be suitable
This module is not suitable for single-mode fiber installations or long-haul links that require wavelengths and optics designed for kilometers of reach. It also requires compatible SFP ports that supply 3.3 V and support the SFP form factor; it will not work in devices that only accept different transceiver types or voltages.
Key specifications
Maximum data transfer rate: 1250 Mbit/s
Optical wavelength: 850 nm
Maximum transfer distance (multimode): 550 m
Connector type: LC duplex

How to use
Insert the Lightwin SFP module into a compatible SFP slot on your switch or router with the LC duplex connector facing the fiber patch cable. Ensure the host device provides a 3.3 V supply and supports the SFP transceiver. Connect LC patch cables to the transmitter and receiver ends, verify link LEDs on the equipment, and use DDM or the host management interface to monitor fiber link status and diagnostics.
What to consider before purchase
Compatibility with the host device's SFP slot and 3.3 V supply
Use of multimode fiber and LC duplex cabling in your installation
Required link distance (up to 550 m for this module)
Quantity needs — this product is sold in a pack of 20 units
Usage recommendations
Use multimode OM3/OM4 fiber where available for best performance at 850 nm, keep connectors clean and dust-free, and verify DDM readings after installation to ensure stable link operation.
