Installation and Configuration Tips

1. Clean Fiber Interfaces Before Use

Microscopic dust particles are the nemesis of optical clarity. Always inspect and clean LC connectors using proper fiber cleaning tools. A single speck can cause major signal degradation.

2. Ensure a Firm and Secure Seating

Insert the transceiver until the locking mechanism engages. A partially seated module may lead to intermittent connectivity or unstable performance.

3. Verify Configuration in RouterOS or SwitchOS

Most MikroTik systems autodetect the transceiver, but manual verification of the interface speed and mode ensures optimal performance. Disable autonegotiation if needed for strict 10G operation.

4. Monitor DDM Metrics Regularly

Use the DDM readings to track optical power, module temperature, and voltage levels. Sudden deviations may signal fiber bending, contamination, or equipment failure.

5. Maintain Proper Fiber Routing

Avoid tight bends and strain on SMF cables. Ensure adequate slack and support to preserve longterm link integrity.

When to Choose the XS+31LC10D for Your Network

This transceiver becomes the optimal choice when a network requires:

• Longdistance 10G connectivity without compromise
