1M Cisco QSFP-100G-CU1M Compatible 100G QSFP28 Passive Direct Attach Copper Twinax Cable

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

Good quality and low price, the cable quality is very good, it is the best choice for communication engineers.

The DAC quality of QSFPTEK is very good. The most important thing is their after sales service. Whenever I have questions about their products, they answer me very enthusiastically.

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.

I have used QSFPTEK products before. Bought twice from their website, both worked fine, engineer communication was excellent and reliable. BTW, their DACs do not include shipping, but are still extremely cheap.

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

I used your network cable instead of the original because the data transfer from and to the original makes no difference but is much lower and can cost a lot of money. thank you very much.

We are a laboratory so very strict about the quality of the DAC twinax cables. I've bought many optical patch cables from QSFPTEK before and their products are always with good quality. So I decided buy 1pc for test at first. My sale representative Talia has sent me detailed test reports with different switches on their test center before shipment. Thanks a lot for her kind help. I've already tested the cable and it works well. I'll buy it again soon.
