Optical SFP+ module MaxLink ML-S+31D-10 1310 nm single-mode 10 km

The MaxLink ML-S+31D-10 is an SFP+ optical transceiver module engineered for 10 Gbps single-mode fiber connections. Operating at a wavelength of 1310 nm, this compact module supports link distances up to 10 km, making it suitable for short metro, campus and data center fiber runs. The module fits standard SFP+ ports on switches, routers and media converters and provides a straightforward way to extend 10 Gbps connectivity over single-mode fiber.

Advantages

The ML-S+31D-10 offers a compact SFP+ form factor with low power consumption and compatibility with standard 10 Gbps SFP+ interfaces. Its 1310 nm wavelength and single-mode design enable stable transmission over distances up to 10 km. The transceiver provides a simple hot-pluggable solution for upgrading network equipment without requiring major hardware changes, and it is suitable for mixed-vendor environments when used with compatible devices.

Suitable for

• 10 Gbps uplinks between switches in data centers and server rooms
• Short metro and campus fiber links up to 10 km
• Connecting media converters and router/switch ports over single-mode fiber
• Redundant or backup fiber paths requiring SFP+ hot-swap capability

Key specifications

• Form factor: SFP+
• Data rate: 10 Gbps
• Wavelength: 1310 nm
• Fiber type: Single-mode fiber (SMF)
• Maximum reach: 10 km (single-mode)
• Interface: Duplex LC connector
• Operating mode: Hot-pluggable

How to use

Insert the ML-S+31D-10 module into an empty SFP+ slot on a compatible switch, router or media converter until it clicks into place. Connect the single-mode fiber patch cord with LC duplex connectors to the module, ensuring proper transmit/receive alignment. Configure the device port for 10 Gbps operation if required by the host equipment. The module is hot-pluggable, so it can be inserted or removed without powering down compliant equipment; follow the host vendor's guidance for hot-swap procedures.

Usage recommendations

Use single-mode fiber of appropriate quality and observe proper connector cleaning to maintain signal integrity. Verify compatibility with the host device and firmware when integrating into multi-vendor environments. For links approaching the 10 km limit, test end-to-end attenuation and consider using optical power budget measurements to ensure reliable operation.
