QSFP-H40G-CU3M — QSFP+ 40 Gbps

The QSFP-H40G-CU3M is a Cisco QSFP+ 40 Gbps passive direct-attach cable (DAC) measuring 3 metres. This intermediate length covers the majority of intra-rack or immediately adjacent rack links without requiring optical components. Pre-terminated, plug-and-play, operational from 0 to 70 °C.

Ideal for spine-leaf architectures where equipment is close but not adjacent, this 3 m passive DAC represents an excellent compromise between reach and acquisition cost. Frequently deployed in private cloud and high port-density virtualization environments. Genuine Cisco hardware, manufacturer warranty.
