0.5M Cisco QSFP-100G-CU0.5M Compatible 100G QSFP28 Passive Direct Attach Copper Twinax Cable

I wasn’t sure how to choose the right DAC cable for my network, so I reached out to customer support. They recommended one that was in stock in the U.S., and the cable arrived quickly.

I’m extremely pleased with the performance of this cable. From the moment I connected it to my networking equipment, everything worked well. There were no hiccups or interruptions during data transfer, allowing for smooth communication between devices.

The price is proportional to the quality, I believe this is a good choice and will buy again.

For the connection of 100G core layer equipment in the rack, we considered using 100G-SR4 modules, but Wendy recommended that we use 100G DAC cables, which reduces costs and improves durability. Thanks to her advice, we saved 40% of our budget.

Compared with transceivers, I prefer DACs. For lazy people like me, plugging in cables is too troublesome. I am very satisfied with qsfptek's DACs!

This DAC is the best one I have used so far, great product, will continue to support.

The quality of the cables is very good, the same as what we get from other high-end brands.

I used to buy a lot of 10G and 40G DAC/AOC cables from QSFPTEK for my switch room and they always did a great job. My 100G DAC sample order also works fine.
