FS makes high grade cables. I use these in both my personal projects as well as professional environment and have never been let down in 3 years of running them.

Very good quality and fast delivery.

The product is great. Keep up the great work.

It does what it is supposed to do and is an easy answer for those who don't have the tooling and training to fab their own fiber.

In the photo of the patch cord that I sent FS, it seemed that the boot of the connector is greater than 90 degrees. But the flex boot connector that FS quoted me was 90 degrees. So lucky that these connector boots can be bent to any degree.

2 rolls of 2KM duplex single-mode patch cable. They will be running across from one side of the data center to the other to connect two switches.

It's a cheap fiber-optic patch cable. Fit into my patch panel and SFP+s with no problem, and got a good, strong link. I don't have a tester, so can't speak for its loss values. It worked fine for me, though.

Signal transmission is very stable, very satisfied! Good quality, well priced.

The cables came nicely packaged and all worked fine. I would buy it again.

Patient and professional service.
