40G QSFP+ активный DAC

We are interested in the 40G DACs, but not sure if they can work with our Cisco devices. The AM quickly replied and asked about our devices’ model, and ensured us the cable could work with my devices. Yeah, they did. This cable does a good job in connecting our switches and adapters. Everything works fine and no problems have occurred so far.

FS guys are always available to help and answer my questions. Thanks for their recommendation, the QSFP+ cable helps us achieve 40Gbps. Will deal with them again and recommend FS to people I know.

We would like to order 7m and 20m DAC cables. 7m was used for connecting the switch and network card in our controlling room, 20m was planned to connect another switch in the downstairs. But FS guys advised us to use 40G module and fibers to achieve 20m connection. He explained the transmission performance would be affected if we chose 20m DAC. We adopted the suggestion. All the DAC, modules and fibers had been used for a while without any problems.
