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.

In order to achieve the 40-10G connections between the adjacent racks, we planned to buy some optical modules for our data center. Since AOC could provide a more cost-effective solution than normal transceivers + cables solutions, so I decided to pick that. Then I found that FS's 40G QSFP+ to 4x10G SFP+ breakout active optical cable might meet my demands. However, with no shopping experiences from FS before, I consulted with the account manager prudently at the beginning. She helped me to check the compatibility between my equipment and the AOCs that I planned to purchase. Quite impressed by their considerate services. Professional and trustworthy, I assumed. So I rest assured and placed my order immediately. Affordable prices and reasonable shipping postage. Lovely! We tested the cables after receiving the packages and used them for months. No compatibility issues in the long run.

Seldom shopping online for our data center, but a friend of mine gave high recognition of FS. So I thought it worth a try. The account manager was professional enough and patiently solved all my questions. Bought several AOC cables this time. The cables arrived well-packaged and fully intact, worked perfectly with our switches. Will consider ordering again if needed.

Lovely price with excellent quality, checked every parts, no problems!

The product was just what I needed. It arrived quickly and was reasonably priced.

I’m quite impressed by FS service. My sales checked the compatibility of my equipment and actual application with me patiently when I bought the transceivers and DACs/AOCs. Service like that is really professional and reliable. In the long run, it avoids the delay of the compatibility problems, shipping errors, returned issues and so on. Actually, I treat my sales as my friend.

It's working fine with Cisco 3850 so far, before I get them, my sales Kyrene sent me test report to show me the TX/RX power, really great support for me. I looked your test program, next time I'd like to buy some Juniper&HP sfps to see how it will work.

The FS transceivers and AOC cables test bed is powerful. FS has many original switches with different brands for testing before shipment. I have to say that it is much helpful for me, because I have many Cisco ASR 9000 Series switches in data center. My sales says FS has the same equipment as well, so the compatibility can be assured. That's the reason why I choose FS and purchase the volume orders from them continually.
