## Summary description

The Mikrotik S-31DLC20D is a high-performance network transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features an SFP interface and an LC fiber optic connector, making it compatible with various MikroTik devices such as RB260GS and RB2011 series. Ideal for enhancing network connectivity and speed.

## Long description

S-31DLC20D is a 1.25G SFP transceiver operating at 1310 nm with a dual LC connector designed for single‑mode fiber links up to 20 km and featuring DDM (Digital Diagnostic Monitoring). The module fits standard SFP ports and is compatible with a range of MikroTik devices as well as many non‑MikroTik SFP hosts.
Advantages
The Mikrotik S-31DLC20D provides a compact SFP form factor with support for 1.25 Gbit/s throughput and DDM for real‑time link diagnostics. Its 1310 nm wavelength and dual LC connector enable reliable single‑mode connections to distances up to 20 km. The module is tested with multiple MikroTik models and offers broad interoperability with other SFP‑capable equipment.
Suitable for
Single‑mode fiber links up to 20 km
Upgrading SFP ports on MikroTik routers and switches (e.g., RB260GS, RB2011 series, CCR1036)
Interoperable use with third‑party SFP hosts
Key specifications
Data rate: 1.25 Gbit/s (SFP)
Wavelength: 1310 nm
Connector: Dual LC
Maximum reach: 20 km (single‑mode fiber)
Features: DDM (Digital Diagnostic Monitoring)
Form factor: SFP (small form‑factor pluggable)
Manufacturer part number (MPN): MTS31DLC20D
EAN: 5902560365986
How to use
Insert the S-31DLC20D module into an SFP port on a compatible device until it clicks into place, then connect LC‑terminated single‑mode fiber cables to the two LC ports. After physical installation, verify link status and SFP recognition in the device management interface. Use DDM readings to monitor optical parameters such as transmit/receive power and temperature.
Usage recommendations
Use single‑mode fiber with appropriate LC connectors and ensure both ends of the link use compatible transceivers. Observe manufacturer guidelines for electrostatic discharge (ESD) protection during installation and avoid bending the fiber beyond recommended radii to maintain signal integrity.
