20m (66ft) 40G QSFP+/4x10G SFP+ブレイクアウトアクティブオプティカルケーブル(AOC FSスイッチ用)

I've put the breakout cable into use and it worked perfect like pointed out in your web shop. I connected a Dell S4112T with a Dell N1548P and (with a fitting configuration within the switches) the cable worked out of the box as I expected.

Using generic FS AOC 40G QSFP+ to 4x 10G SFP+ cables (quad breakout cables) in various lengths to connect Mikrotik CRS326 Cloud Router Switches to various vendors servers switches and routers. Works great as you would expect with AOC. One thing to note: whether you get link light on 10G ends or not, you need to configure CRS326 breakout ports with autonegotiate off and hard code 10G/full advertisment to actually pass traffic. 10G endpoints should leave autonegotiate on.

Thanks to FS team's great service and fast delivery, our urgent request was fulfilled timely.
