Cisco QSFP-DD to 4x100GBASE-CR2 Passive Breakout Copper Cable, 1 m

Breakout cables let one high-speed port feed several slower ones. The Cisco QDD-4ZQ100-CU1M takes a QSFP-DD port and fans it out into four 100GBASE-CR2 connections, using passive copper over a 1 m length.

The typical use is connecting a 400GbE switch port to several 100G devices without optics in the middle. The speed is 400GbE over copper media, and the length is 1 m, so it suits equipment that sits close together.

Choose from new, refurbished and used units. New and refurbished ones come with a choice of 1 year or 3 years of warranty; used units come with 90 days. Check which end of the breakout your 100G devices need to plug into before ordering, and add the part to your RFQ with the quantity.
