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

This 100G QSFP28 DAC cable is well built with solid connectors and a secure fit. The cable has good flexibility, making it easy to manage inside the rack. A reliable option for short-distance high-speed connections.

This cable is a reliable choice for high-speed interconnections within cabinets or between adjacent cabinets. The price is also very nice.

Compared to optics, this 100G DAC cable is a very cost-effective solution. It is plug-and-play, and latency is practically non-existent. The signal performance is excellent. It's a great choice for short connections in the data center.

This QSFPTEK 100G DAC cable was ready to use with our servers straight away. Latency is almost zero and speed is excellent. The only drawback is that the cable is slightly stiff in tight racks. Nevertheless, it's an excellent solution for short, high-speed connections.

The performance transmission of this DAC is good. I suggest that more detailed instructions and documentation can be provided to make it more convenient to use.

I am very impressed with this DAC cable. The last batch I bought had a very soft cable that was not too hard to manage. Within the 1-3m distance I need, using a DAC is a very good solution, and the cost is slightly cheaper than the optical module combination.

For our short-distance transmission interconnection in the data center, QSFP28 100G DAC can be perfect. We mainly use Cisco and Mellanox two brands of switches, which are compatible with both can do plug and play, QSFPTEK Box is very easy to use. The performance of the product is also very stable.

This 100G DAC cable performed well in interconnecting servers over short distances, the link was established quickly and data transfer was stable with no degradation or miscoding. Considering the price of this product, there is no room for nitpicking on features. However, it is worth noting that the material of the DAC cable is hard and not very flexible for bending, so if your rack space is limited, you should consider whether it is suitable for your cabling environment.

QSFPTEK responded to my emails and requests promptly and shipped my order even faster than I expected. I'm extremely satisfied with both the quality and service. Thank you!

There is no doubt that the DAC connection is much cheaper than an optical module paired with fiber, especially for short-haul scenarios within our data centers. We chose to order large quantities of this product and were very pleased with the great price we received from QSFPTEK sales!
