Cable breakout de cobre de conexión directa 100G QSFP28 a 4x25G SFP28 (pasivo)

I got a 1M and 2M 100G to 4×25G cables. I have these connected into 25G Mellanox Connect4-x Nics and Mellanox 2100 100G switch. The cables work perfectly with both devices and were seen immediately. Seems to be good quality build of cables and performs as advertised.

We are looking for a cable to connect Cisco N9K-C93180YC-EX and Mellanox 4421/4121A-ACAT cards. The 100G QSFP28 to 4x25G SFP28 DAC breakout cables we finally got were priced very competitively and worked exactly as intended. Considering that there will be the needs to work these cables on other switches like Mellanox SN2700/SN2100, Cisco, Arista, Juniper, etc that can do the 100G QSFP or 25G QSFP connections, we turn to the FS box which we have been eyeing for some time now. The AM has helped confirm that it can do the coding of the 100G QSFP28 side of the breakout DAC cable. With it, the 100G side of the 100 to 4x25G DAC cable is able to go to any switch. Would like to share more about the use of FS box (maybe an UNBOXING video on YouTube) later on.

I have to connect Xilinx VCU1525 development board with Intel XXV710 card. My distance is about 3m, and I want DAC or AOC for this 100G-25G connection. My account manager suggested this customized DAC cable with one end coded as generic and the other coded for intel. Meanwhile, they also told me to use 100G SR and 25G Intel compatible transceivers together with MTP-LC fiber patch cables. But finally I chose the DAC due to the short distance needed and lower costs. I found it worked very well with my devices.Their professional solutions helped me a lot.
