Great for home labs!
The LC to LC Fiber Keystone is a great solution for my 10-gig home network. These keystones allow for a clean and organized installation while maintaining full speed and performance. The connectors fit securely, and I’ve experienced no issues with signal quality or speed. They are a perfect choice for anyone looking to create a neat and efficient fiber network without compromising on performance. Highly recommended for high-speed setups!

Great performance, economical price
These keystones have worked great so far, they snap in securely, and there is no loss in performance. If you have fiber runs and don't need enterprise class fiber management or you just need to terminate in a wall plate these are great option.

Work very well
I have used these in several installations. They fit well, and do not create any signal problems. If you are changing these out in compatible wall plates keep a small flat blade screwdriver with you to make removal easier.

Works as intended
I've been using fiber from device-to-device for a couple years, and this winter I'm on a mission to upgrade and clean up my home network. I have a few different style of keystone wall plates around the house, and I can confirm this LC keystone fits perfectly in a Legrand/On-Q F3406. I've moved over 1TB of data on that interface (PC to NAS / PC to world) in 72 hours and it has counted 0 errors.

First time using a fiber keystone
This is the first time I have used a fiber keystone it and works great. I installed the fiber keystone in slot 13 on the black patch panel and you can see the keystone in the photo attached. There were no problems inserting the fiber connectors into the keystone. I really like using fiber over copper cables because of the size and reduced heat and it is very easy to identify a fiber connection. I just bought a 2 pack to make sure they work and I will be getting more.
