The cable worked okay, but I’m a big fan of FS fiber optic modules which make FS one of the trustworthy suppliers on the market today.

FS customer service has never been caught up by those who were unable to get back to me in a timely manner and weren’t super well-versed in their product’s technical details.

The AM was enthusiastic about solving my problems and helping me track my package all the time. After receiving my order, I plugged the AOC cables into my switches and did the compatibility test, they worked great and no errors occurred until now.

Bought this product for my Mellanox switches. Very nice packaging. All the AOC cables can work normally on my switches and offer a smooth data transmission.

The 56G QSFP+ AOC fits into the slot of Mellanox MSX6512 216 port FDR IB switch and it WORKS!
