It bridges the gap between affordability and enterprise-grade reliability, which makes it one of the most popular transceivers available through ITMan.
Comprehensive Overview of MikroTik XS+31LC10D Transceiver
The MikroTik XS+31LC10D Transceiver is a 10 Gigabit SFP+ optical module designed for single-mode fiber (SMF) links. It supports a data transfer rate of up to 10 Gbps and an optical reach of up to 10 kilometers, making it suitable for connecting switches, routers, and servers across distant network segments.
This transceiver uses 1310 nm wavelength optics and features dual LC connectors, which ensure stable duplex transmission between two endpoints. The device is compliant with the SFP+ Multi-Source Agreement (MSA), meaning it can also work with a wide range of third-party equipment that follows the same standard, although the best performance is achieved with MikroTik hardware.
Another key highlight of the XS+31LC10D Transceiver is its low power consumption—a feature particularly valuable for data centers that require efficient cooling and energy savings. Built with advanced optical components, the module maintains precise signal transmission with minimal attenuation and low latency, even in high-density fiber infrastructures.
This part number—XS+31LC10D—reflects MikroTik’s naming convention:
- XS+ = SFP+ (10 Gbit/s class)
- 31 = 1310 nm wavelength
- LC = LC-type duplex connectors
- 10D = 10 km distance
Together, these specifications define a module that’s perfectly tuned for long-distance point-to-point fiber connections at 10 Gbps speeds.

The module can also auto-negotiate link parameters to maintain signal stability between different network devices.
Understanding Fiber Optics with XS+31LC10D
The MikroTik XS+31LC10D Transceiver operates using light-based communication over single-mode fiber. At 1310 nm wavelength, the signal encounters minimal dispersion and attenuation, maintaining its integrity across long distances.
In comparison to multi-mode transceivers like the S+85DLC03D, this module is specifically optimized for environments that require both long reach and high speed—for example, connecting core switches across data center floors or linking distant facilities.
The performance benefits include:
- Reduced packet loss over long distances
- Lower latency than copper-based connections
- Higher resistance to electromagnetic interference
This ensures stable, high-quality transmission suitable for applications such as video streaming, VoIP backbones, and virtualization traffic.
Installation and Configuration Tips
Integrating the XS+31LC10D Transceiver is simple, but a few steps help ensure optimal performance:
- Check Compatibility – Verify that your MikroTik device supports SFP+ modules.
- Insert Gently – Plug the transceiver into the SFP+ port until it clicks.
- Attach Fiber Cable – Use a clean LC connector and ensure proper polarity (Tx ↔ Rx).
- Monitor Status – Check interface status via MikroTik RouterOS (
/interface ethernet monitor). - Adjust Distance Settings – For long runs, confirm that attenuation values are within acceptable limits.
Proper installation prevents data loss and ensures your XS+31LC10D Transceiver delivers consistent 10 Gbps links.
When to Choose the XS+31LC10D for Your Network
If your deployment spans large areas—such as linking buildings or distant network racks—this module offers an unbeatable balance between reach and cost. Compared to short-range options like the S+85DLC03D (300 m), the XS+31LC10D can handle far longer runs without expensive repeaters.
Moreover, enterprises migrating from 1 G SFP to 10 G SFP+ infrastructure will find the XS+31LC10D Transceiver a straightforward, plug-and-play upgrade path that immediately boosts bandwidth capacity.
Ensuring Clean and Reliable Fiber Links
A critical aspect of maintaining performance is fiber cleanliness. Even a small dust particle can severely affect optical transmission. Always use protective caps and cleaning tools before connecting fibers.
MikroTik’s XS+31LC10D has built-in digital diagnostics (DDM) features that let administrators monitor parameters such as temperature, transmit power, and signal loss. You can access these values directly through RouterOS to predict issues before they cause downtime.
