## Summary description

SFP28 optical transceiver MaxLink ML-S28-SM-10 supports 25G data rate over single-mode fiber with up to 10 km reach. It uses dual LC connectors and provides Digital Diagnostic Monitoring (DDM) for real-time status of temperature, optical power and bias current. Designed for 25G Ethernet and high-speed data links in data centers, carrier and enterprise networks.

## Long description

The MaxLink ML-S28-SM-10 SFP28 optical module is a compact transceiver designed for 25G data links over single-mode fiber with a reach of up to 10 km. Supporting 25 Gigabit Ethernet, this module uses dual LC connectors and implements Digital Diagnostic Monitoring (DDM) to report real-time operating parameters such as temperature, optical transmit and receive power, and laser bias current. The small form-factor pluggable design makes it compatible with SFP28 ports in switches, routers and servers intended for high-speed links in data centre, carrier and enterprise network environments.
Advantages
The module delivers a 25G data rate over single-mode fiber with a 10 km range while occupying a low-profile SFP28 form factor suitable for high-density equipment. Dual LC connectors provide standard physical interfacing and the integrated DDM function enables continuous monitoring of critical optical and thermal parameters to aid in maintenance and troubleshooting. The transceiver is designed for interoperability with common 25G Ethernet systems and for straightforward hot-plug installation in supported SFP28 sockets.
Suitable for
25G Ethernet uplinks between switches and aggregation devices
High-speed server-to-switch connections in data centres
Carrier and metro links requiring single-mode fiber connections up to 10 km
Network upgrades to 25G where SFP28 ports are available
Key specifications
Nominal data rate: 25 Gbps
Fiber type: single-mode
Maximum reach: 10 km (on appropriate single-mode fiber)
Connector type: 2x LC duplex
Form factor: SFP28
Monitoring: Digital Diagnostic Monitoring (DDM) for temperature, optical power and bias current
How to use
Insert the SFP28 module into a compatible SFP28 port on a switch, router or server while the host device is powered according to the manufacturer’s guidelines for hot-pluggable optics. Connect single-mode fiber patch cords to the LC duplex ports, observing correct transmit/receive orientation. After installation, verify link status and data rate on the host device management interface and review DDM parameters to confirm normal operating temperature and optical power levels. Follow the equipment vendor’s procedures for firmware or compatibility checks if necessary.
Usage recommendations
Use single-mode fiber rated for the intended distance and maintain clean LC connectors to ensure optimal optical performance. Monitor DDM readings periodically to detect signal degradation or thermal issues. For installations in critical environments, validate compatibility with the switch or router vendor and perform end-to-end testing after deployment.
