Mellanox Mellanox Compatible SFP28 10/25G 850nm SR.

An optical transceiver has to match the equipment it plugs into, the link speed, and the fibre already installed. Single-mode and multi-mode are not interchangeable, and the connector type and supported distance must be the same at both ends of the run. Some vendors accept only modules coded for their own hardware, so confirm compatibility before ordering.
