TP-Link Omada SM9110-SR4 network transceiver module Fiber optic 100000 Mbit/s QSFP28 850 nm

The TP-Link Omada SM9110-SR4 is a QSFP28 multi-mode fiber optic transceiver module designed for ultra-fast Ethernet links. It operates at an 850 nm wavelength and supports 100GBASE-SR4 and 40GBASE-SR4 applications. The module is hot-pluggable and compatible with QSFP28 ports, providing high-density connectivity for data center and enterprise switching equipment.

Advantages

This transceiver supports Digital Diagnostic Monitoring (DDM) for real-time status information and offers a compact QSFP28 form factor for high port density. It supports 100G Ethernet up to 100 m and 40G Ethernet up to 150 m over OM4 multimode fiber, operates on a 3.3 V input, and is RoHS-compliant. The module uses MPO/MTP connectors and is suitable for integration into existing optical networks.

Suitable for

• Data center aggregation and spine-leaf switching
• High-speed uplinks between switches and routers
• Short-reach 100G or 40G links over OM4 multimode fiber
• High-density QSFP28 port deployments

How to use

Install the SM9110-SR4 into a compatible QSFP28 port on a switch or transceiver cage while the device is powered on or off (hot-pluggable). Connect the MPO/MTP multimode fiber cable (OM4 recommended) to the module, ensuring correct orientation and secure seating of the connector. Verify link status using the host device and monitor diagnostic parameters via supported management interfaces.

Recommendations

Use OM4 multimode fiber for the specified distances, verify compatibility with the host vendor's QSFP28 ports when required, and follow ESD handling and manufacturer installation guidelines to ensure reliable operation.
