How to use
Verify that the target network device supports SFP28 modules and the required 25 Gbit/s link speed. Power down the port if recommended by the equipment vendor, insert the transceiver into the SFP28 slot until it clicks into place, and connect a compatible multimode fiber patch cable to the module. After installation, check link status and configure port settings on the switch or router as needed to enable the interface at the desired speed and duplex.
Usage recommendations
Use the transceiver with OM3/OM4 multimode fiber for short-reach applications, follow manufacturer guidance for electrostatic discharge precautions when handling, and ensure firmware or driver compatibility with the host device. For reliable performance at 25 Gbit/s, keep fiber connectors clean and verify link parameters in the network equipment's management interface.
