素早い対応で助かりました。今後ともよろしくお願いいたします。

I can't say enough about the great support we received from FS.
Got the devices up and running. Many thanks to Sylvia & Rig for their help.

Great Product, Shipping was fast and really good service from FS

I've ordered many of these over a few years for different projects. They work right out of the box and the customer service is always great.

Good, the modules were installed last week and are working perfectly!

Excellent quality....fast shipping. Thank you!!

Great product and customer service. Fast shipping!

These MM SFP modules have worked well in in the Grandstream Switches they were ordered for. The shipping is fast and the price is reasonable. They usually have them stocked in the US for faster delivery.

They just work as expected, I didn't do the deep dive tests but basic usage works excellent.

Why would anyone buy any other GBIC? This just works and it's essentially disposable at this price point if something did go wrong.
But, it just works, so you only need one, and you can spend your savings on so many other things.
