Q&A

How long is the Cisco QSFP-100G-CU5M?

The Cisco QSFP-100G-CU5M is a 100G QSFP28 direct-attach copper cable measuring 5 m. Because the modules are factory-terminated at both ends, the cable cannot be shortened or re-terminated in the field — order the exact length required.

Is the Cisco QSFP-100G-CU5M copper or optical?

It is a direct-attach copper cable (Passive copper (twinax)): Passive, no external power, terminated with QSFP28 to QSFP28 connectors. It carries the link without separate transceivers at each end.

How does the Cisco QSFP-100G-CU5M compare with the Cisco QSFP-100G-CU3M?

The QSFP-100G-CU5M reaches 5 m assembly length over Passive copper (twinax), while the QSFP-100G-CU3M reaches 3 m assembly length over Passive copper (twinax). Pick the shortest reach that covers the link distance — going longer than needed costs more and adds optical budget margin you will not use.
