Awesome product works great with my Mikrotik router and switch (RB4011 and CSS356).
FS please keep up the great service, also a huge thanks to my account manager who really took great care and helped A LOT.

Shopping at FS was fantastic. I have to say this product was exactly what I needed for my Cisco Nexus series switches. Worked fine on my switch. Also surprised by the customer service here. They offered top-notch customer service and responded to your needs immediately. Keep up the good work. Appreciated!

Very pleased with the quality of the 10G SFP+ DAC. I ordered many different lengths of DAC cables and used them on my Cisco ASR 9001 router and Nexus 3064 X switch. They all worked well and there were no interface issues at all. Zero packet loss. Highly recommend these items which feature with great quality and excellent performing.

I know there are some people who are hesitant to use copper products like this but, it works just fine. I put this in my FS 3900 switch to another one, and it worked flawlessly. It is SHORT since my two switches are close to each other on my rack. There is no difference on the performance of DAC solution and the fiber cable plus transceivers, and the DAC cable was priced very competitively. All in all, I am extremely happy with this purchase and will consider buying from now on as needed for any projects.

This does a good job in connecting FS switch S3900-48T4S to Netgear M4300. Everything works fine and no problems have occurred so far. There is no reason for which I have to take away a star.

The twinax cables arrived on time with a sturdy package, I used them on my Cisco 9300-48T and C9500-40X switches, easy to plug and work perfectly with those devices. Satisfied with this purchase.

I need DAC cables for connecting my two Catalyst 4500X and I made an order of another passive one without noticing I made a mistake. Actually, Catalyst 4500X only supports the active DAC. Luckily, my account manager checked my ordered products with me and changed to this active one. They are very solid and just work great with my switches. Will buy more from here.

DACs are pretty much a commodity item, since fiber optics are normally an oddly expensive one. Have used them for connecting switches, no compatibility issues.

Certainly cannot complain about the service. Cable was delivered very efficiently. Will certainly use again if I need to source cables again.

They have all the products you would like and are able to help you choose what is best for you.  There are so many options to purchase these days and I am a big user of Amazon but I will use B&H every single time for any technical equipment I need because their customer service so is phenomenal.  The have the same products and same free two day shipping.  The difference is their customer service and online chat feature are just great.  I needed help choosing between two camera's and I told them what I was using it for and they actually recommended the less expensive one to me because the other one would have been over kill.    Can't rave enough about them!
