Product information

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.
