QSFP-4SFP10-CU0-5 — QSFP+ 40 Gbps

The Cisco QSFP-4SFP10-CU0-5 is a passive breakout DAC cable in QSFP+ form factor that splits a 40 Gbps aggregate link into four SFP+ outputs at 10 Gbps each, over a length of 0.5 metres. Pre-terminated in copper, it installs without a separate module and tolerates temperatures from 0 to 70 °C.

This 0.5 m version is designed for very short-distance interconnects between a QSFP+ 40G switch and four SFP+ 10G servers or devices located in the same rack. The ultra-short 0.5 m length sets this breakout cable apart from longer variants and reduces cable congestion in dense enclosures. Genuine Cisco hardware, manufacturer warranty.
