QSFP-H40G-CU0-5M — QSFP+ 40 Gbps

The QSFP-H40G-CU0-5M is the shortest passive QSFP+ DAC cable in the Cisco 40G family, with only 50 cm of pre-terminated twinax for 40 Gbps throughput. This 0.5 m length is designed to connect two devices mounted in contiguous slots within the same chassis or rack, where any longer length would generate unwanted cable slack. Operating temperature: 0 to 70 °C.

High-density backplane deployments or stacked switches within a single rack benefit particularly from this ultra-compact cable. The QSFP-H40G-CU0-5M is the choice of engineers focused on optimising airflow and cable organisation in very high port-density environments. Genuine Cisco hardware, manufacturer warranty.
