## Summary description

Lightwin LWO-SFP100-3155-20 is an SFP fiber optic transceiver module for Fast Ethernet applications supporting up to 155 Mbit/s. It uses an LC simplex connector for singlemode links with a maximum reach of 20,000 m, operates at 3.3 V and includes DDM capability. Metallic housing and RoHS compliance make it suitable for network equipment requiring compact SFP uplinks and long-distance fiber connections.

## Long description

Lightwin LWO-SFP100-3155-20 is an SFP fiber optic transceiver designed for Fast Ethernet links supporting up to 155 Mbit/s. The module fits standard SFP slots, uses an LC simplex connector for singlemode fiber and supports a maximum link distance of 20 km. It operates from a 3.3 V supply, features a metallic housing, DDM capability for diagnostic monitoring, and complies with RoHS requirements.
Advantages
The transceiver provides reliable long-distance singlemode connectivity in a compact SFP form factor suitable for switches, media converters and other network equipment. Built-in DDM enables real-time monitoring of optical parameters while the metallic enclosure offers mechanical robustness and improved heat dissipation. Support for the 155 Mbit/s Fast Ethernet data rate and LC connector ensures compatibility with common fiber infrastructure.
Suitable for
Fast Ethernet uplinks and links requiring 155 Mbit/s bandwidth
Singlemode fiber connections up to 20 km
Network switches, routers and media converters with SFP ports
Deployments needing SFP compact form factor and DDM monitoring
When it may not be suitable
This transceiver is not intended for multimode fiber networks or for applications that require data rates higher than 155 Mbit/s (for example Gigabit Ethernet). It is also unsuitable where a different connector type (such as SC or ST) or a different wavelength/bi-directional configuration is required.
Key specifications
Data rate: 155 Mbit/s (Fast Ethernet)
Fiber type: Singlemode
Connector: LC simplex
Maximum reach: 20,000 m (20 km)
Operating voltage: 3.3 V
Form factor: SFP (small form-factor pluggable)
Diagnostics: Digital Diagnostic Monitoring (DDM)
Housing: Metallic
How to use
Insert the Lightwin SFP transceiver into a compatible SFP slot on your network device until it clicks into place. Connect a singlemode LC fiber cable to the module's LC simplex port, observing correct transmit/receive orientation. Ensure the host device supplies 3.3 V to the SFP slot and enable the corresponding Fast Ethernet port in the device configuration. Use the DDM function via the host system to monitor optical power and temperature as needed.
What to consider before purchase
Verify your network equipment has SFP slots that accept third-party transceivers
Confirm you require singlemode LC connectors and a 20 km reach
Ensure 155 Mbit/s Fast Ethernet speed meets your bandwidth needs
Check whether DDM support is necessary for your monitoring setup
Usage recommendations
For reliable operation, use singlemode LC patch cables of appropriate length, avoid excessive bending of fiber, ensure firm seating of the SFP in the host slot, and monitor DDM parameters after installation to verify optical link health.
