I have received the cassettes. The service attitude is very good. When I have any questions about matching, they are answered in detail.Great service!

Color coding at a glance: The color of the box's front adapter housing follows the TIA/EIA-568.3-D recommended color coding scheme, allowing us to easily identify different types of connections.

I would like to try to maximize our rack space. Thank FS for your assistance, gave me an excellent solution

Overall very good product. I didn't have a problem.

The plug-style lock design of this cassette allows for easy removal and installation, without the need for any additional tools. Convenient and efficient

Good company. The product descriptions and documentations are comprehensive, especially the file about the polarity. I am happy to buy the right product.

Very easy to use. No tool is needed, just need to snap in plastic rivets, save much time.

Love these. Just what I was expecting and wanting. They are easy for to install and matches my enclosure well. I may buy more in the future.

Like me, you'll probably compare this to the more expensive name brand of Corning. I've got cabinet, cassettes, and switchs on this and they're worked great for over a year. I've got the same unit in two offices as well and haven't had any problems with those either. I've also owned Corning and can say that FS products are cost-effective.
