Q&A

How long is the Cisco QSFP-4SFP10G-CU1M?

The Cisco QSFP-4SFP10G-CU1M is a 40G QSFP+ direct-attach copper cable measuring 1 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-4SFP10G-CU1M copper or optical?

It is a direct-attach copper cable (Passive copper (twinax)): Passive, no external power, terminated with QSFP+ to 4 × SFP+ connectors. It carries the link without separate transceivers at each end.

How does the Cisco QSFP-4SFP10G-CU1M compare with the Cisco QSFP-H40G-CU5M?

The QSFP-4SFP10G-CU1M reaches 1 m assembly length; 40G to 4 × 10G breakout over Passive copper (twinax), while the QSFP-H40G-CU5M reaches 5 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.
