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

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!

The price of the item was the best I could find, and the ordering process was quick and easy. Definitely a great value for the quality and performance offered.

The 100G DAC is solidly constructed and feels highly durable. Its flexibility makes it effortless to route through tight spaces. It performed exactly as expected and met our needs perfectly.

Using this 1m QSFP28 DAC has reduced the cost of our solution quite a bit, and the DAC solution is more cost-effective and affordable for us than the option of an optical module. It's also worth noting that we ordered large quantities and the QSFPTEK sale provided us with discounted pricing.

I apologize for misremembering the name of the sales person who assisted me with my order. I was very impressed with her and she was really very professional. I made a mistake in the quantity of my first order and contacted her immediately and she made corrections to my order immediately. That made me feel at ease!
