SFP-50G-CU3M — SFP56 25/50 Gbps

The SFP-50G-CU3M is a Cisco Direct Attach Copper cable in SFP56 form factor, supporting 25 or 50 Gbps over 3 m. This passive, pre-terminated cable covers connections between devices three meters apart, typically between adjacent bays or between a patch panel and a distribution switch.

The 3 m length extends the connection range compared to the 1 m and 2 m variants, while remaining within the low-cost passive range. It is widely used in leaf-spine architectures to link adjacent switches without the need for fiber. Genuine Cisco hardware, manufacturer warranty.
