## Summary description

Lightwin LWO-SFP100-SX is a multimode SFP transceiver supporting 155 Mbps data rate and up to 2 km reach over multimode fiber. It features LC duplex connector, Digital Diagnostic Monitoring (DDM) and is designed for short-range fiber links in switches, routers and media converters where reliable 155 Mbps connectivity is required.

## Long description

Lightwin LWO-SFP100-SX is a multimode SFP transceiver module designed for 155 Mbps synchronous or asynchronous links, providing up to 2 km reach over multimode fiber. The module uses an LC duplex optical interface and includes Digital Diagnostic Monitoring (DDM) for real-time reporting of optical power, temperature and other transceiver parameters. It is intended for use in network equipment such as switches, routers and media converters where stable short-range fiber connectivity is required.
Advantages
This SFP transceiver delivers a fixed 155 Mbps data rate and a multimode optical design that supports reliable short-distance links up to 2 km. The LC duplex connector ensures a compact, industry-standard interface for easy installation in SFP ports. Integrated DDM allows network administrators to monitor key parameters such as transmit/receive power, temperature and laser bias current for proactive maintenance and troubleshooting. The module’s form factor and multimode wavelength make it compatible with a wide range of legacy and current networking devices that accept SFP optics.
Suitable for
Short-range multimode fiber links within enterprise LANs
Connecting switches, routers and media converters that require 155 Mbps interfaces
Network segments where optical monitoring (DDM) is needed for diagnostics
Upgrading or maintaining legacy synchronous transmission systems
When it may not be suitable
This transceiver is not suitable for long-distance singlemode fiber links or applications that require data rates higher than 155 Mbps, such as 1 Gbps or 10 Gbps networks. It is intended specifically for multimode fiber; using it on singlemode fiber or with mismatched fiber types and connectors may result in poor performance or no link. Environments requiring enterprise-grade power or extended temperature specifications beyond the module’s design should verify compatibility with system requirements.
Key specifications
Data rate: 155 Mbps
Maximum reach: up to 2 km on multimode fiber
Fiber type: multimode
Connector type: LC duplex
Monitoring: Digital Diagnostic Monitoring (DDM)
Form factor: SFP transceiver
How to use
Install the transceiver into an available SFP slot on a compatible switch, router or media converter while the host device is powered on or off, following the equipment vendor’s handling guidelines. Connect LC duplex multimode fiber patch cords to the transmit and receive ports, ensuring correct polarity. After insertion, verify the host device recognizes the module and check link status LEDs or management interface. Use the DDM functions through the host device to view diagnostic values like optical power levels and temperature for ongoing maintenance.
What to consider before purchase
Confirm the host device supports SFP transceivers and the required 155 Mbps data rate.
Verify the network uses multimode fiber and that LC duplex connectors match existing patch cords.
Ensure the 2 km reach meets the distance requirements of the planned link.
Check that the host platform supports DDM reporting for optical diagnostics.
Usage recommendations
For reliable operation, use high-quality multimode fiber patch cords with correct polarity, monitor DDM parameters after installation to confirm adequate optical margins, and test links end-to-end before deploying into production. Replace or clean connectors if optical power levels indicate excessive loss.
