## Summary description

SFP+ optical module MaxLink ML-S+31D-10 operates at 1310 nm wavelength for single-mode fiber links up to 10 km. Designed for 10 Gbps SFP+ ports, it provides a compact transceiver solution for connecting switches, routers and media converters. Suited for metro, campus and data center links where reliable short-range single-mode connectivity is required.

## Long description

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.
