Dell V250M-RFB is a refurbished Twinax direct-attach cable for short network links between equipment with SFP+ ports. Its SFP+ connectors at both ends provide a direct connection without separate cable-side transceivers.
At 1 m long, it suits nearby devices, such as switches, servers, or network adapters arranged close together. The listing specifies 10 Gbps connectivity, making this cable a practical option for a short 10GbE link where both connected ports support SFP+ and the required connection type.
