## Summary description

SFP optical module MaxLink ML-S3155out-3 supports WDM operation with wavelengths 1310/1550 nm and a link distance up to 3 km. Designed for insertion into SFP ports of switches and media converters, it enables fiber connection between devices using wavelength-division multiplexing. Suitable for extending network links, connecting equipment across short fiber runs and integrating legacy and new systems.

## Long description

The Optical SFP Module MaxLink ML-S3155out-3 WDM 1310/1550nm 3km is a small form-factor pluggable transceiver designed for insertion into SFP ports of switches and media converters. It supports wavelength-division multiplexing (WDM) with transmit and receive wavelengths at 1310 nm and 1550 nm, enabling fiber links up to 3 km. The module is intended for creating point-to-point fiber connections, extending short-distance links and integrating equipment that requires WDM optics.
Advantages
This SFP module provides WDM capability in a compact SFP form factor, allowing two-way communication over a single fiber when paired with a complementary WDM transceiver. The unit supports link distances up to 3 km, making it suitable for short fiber runs between buildings or within campus environments. Its plug-and-play design simplifies installation into standard SFP ports on switches and media converters without additional configuration.
Suitable for
 Extending network links over single-mode fiber up to 3 km
 Connecting switches and media converters using WDM
 Integrating legacy and new network equipment that use SFP ports
 Point-to-point fiber links where fiber count is limited
Key specifications
 Form factor: SFP (small form-factor pluggable)
 Wavelengths: 1310 nm and 1550 nm (WDM operation)
 Maximum link distance: up to 3 km
 Application: single-mode fiber point-to-point WDM connection
 Compatibility: designed for insertion into SFP ports of switches and media converters
How to use
Insert the ML-S3155out-3 SFP module into an available SFP port of a switch or media converter while the device is powered off or following the host equipment manufacturer's hot-plug guidance. Use an appropriate single-mode fiber patch cable and, when implementing WDM, pair this module with the complementary WDM transceiver that uses opposite transmit/receive wavelengths. Verify link status indicators on the host device to confirm the optical link is established and functioning at the required distance.
Usage recommendations
Ensure fiber connectors are clean before mating and select single-mode fiber appropriate for 1310/1550 nm wavelengths. When planning WDM links, confirm that the paired transceiver uses the complementary wavelength orientation. Follow the switch or media converter vendor guidance for supported SFP modules and hot-plug procedures to avoid operational issues.
