SFP28 Optical Module MaxLink ML-S28-MM-100 25Gb/s multimode 100m, duplex LC

The MaxLink ML-S28-MM-100 SFP28 optical module provides 25Gb/s short-reach connectivity over multimode fiber with duplex LC connectors and a maximum link distance of 100 meters. Designed for use in data centers, top-of-rack switches and high-density server interconnects, this hot-pluggable transceiver supports industry-standard digital diagnostics to monitor link health. Its compact SFP28 form factor and low power consumption enable straightforward integration into existing 25GbE network ports and media converters that accept SFP28 modules.

Advantages

This SFP28 multimode transceiver offers a balance of high bandwidth and short-reach performance suited for intra-rack and adjacent-rack links. Hot-pluggable installation simplifies field upgrades and replacements without powering down equipment. The module’s support for SFF-8472 diagnostics provides real-time monitoring of parameters such as optical power and temperature, aiding in maintenance and troubleshooting. Low power consumption and the standardized LC duplex interface make it compatible with a broad range of switches, servers and optical ports designed for 25Gb/s multimode links.

Suitable for

• 25 Gigabit Ethernet connections between servers and top-of-rack switches
• Short-reach links inside data center racks and between adjacent racks
• Upgrading or expanding switch and media converter ports to 25GbE multimode
• Environments requiring hot-swappable transceivers and link diagnostics

Key specifications

• Data rate: 25 Gb/s
• Fiber type: Multimode fiber (MMF)
• Maximum reach: 100 meters on multimode fiber
• Connector: Duplex LC
• Form factor: SFP28 (hot-pluggable)
• Diagnostic monitoring: SFF-8472 compliant digital diagnostics
• Typical power consumption: low-power SFP28 class

How to use

Insert the SFP28 module into a compatible SFP28 port on a switch, server NIC or media converter while the device is powered on to take advantage of hot-pluggable capability. Use duplex LC patch cables to connect the module to multimode fiber infrastructure following transmit-to-receive pairing. After insertion, verify link status through the host device’s management interface and, when available, monitor optical parameters via the module’s digital diagnostics (SFF-8472) to confirm signal levels and temperature are within expected ranges.

Usage recommendations

For reliable 25Gb/s multimode performance, use OM3 or OM4 multimode fiber and quality duplex LC patch cords, maintain proper fiber bend radius, and ensure connectors are clean before mating. Validate compatibility with the host device vendor’s supported transceiver list when possible and monitor SFF-8472 diagnostics periodically to detect link degradation early.
