Fiber optic transceiver module MikroTik S+31DLC10D — SFP+ interface, 10 Gbps (10000 Mbit/s)

MikroTik S+31DLC10D is a 10G SFP+ fiber optic transceiver designed for single-mode links up to 10 kilometres using an LC connector and a 1310 nm wavelength. The module supports a maximum data rate of 10,000 Mbit/s and is intended for high-speed uplinks, inter-switch connections, data centers, enterprise networks and carrier links. Units are tested to be compatible with MikroTik CCR1036-8G-2S+ and CCR1036-8G-2S+EM and also work with compatible non‑MikroTik SFP devices.

Advantages

The S+31DLC10D provides a compact SFP+ form factor for 10 Gbps optical connectivity over single-mode fiber, offering long-reach transmission up to 10 km at 1310 nm. Its compatibility with MikroTik CCR1036 series equipment and with standard SFP devices ensures flexible deployment in mixed vendor environments. The module is supplied as a single unit and is suitable for backbone and aggregation links where a reliable optical uplink is required.

Suitable for

• High-speed uplinks between switches and routers
• Inter-switch connections in campus and data center networks
• Optical backbone and aggregation links
• Carrier and enterprise network links up to 10 km

How to use

Insert the S+31DLC10D transceiver into an available SFP+ port on compatible network equipment, ensuring the module is fully seated and latched. Connect single-mode LC fiber cables to the transceiver, observe correct Tx/Rx orientation and verify link LEDs or management interfaces to confirm connectivity. Configure the connected devices as required for 10 Gbps optical links and monitor link status through the switch or router management tools.

Usage recommendations

Use single-mode fiber with LC connectors and maintain clean connector end-faces to ensure optimal signal quality. Verify compatibility with the host device firmware and perform link tests after installation. For distances near the 10 km limit, check fiber attenuation and consider margin for splices or connectors.
