10 pcs Duplex LC to LC Fiber Coupler, Multimode Fiber Optic LC Keystone Jack Coupler for Fiber Wall Plate,Surface Mount Boxes(Fiber Optic Adapter, OM3/OM4)

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.

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.

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!

These were just slightly too large to fit my Cable Matters patch panel. It was close enough that I could squeeze the face through but the latch would not clip. It might have been possible to force it to latch but it would have been impossible to ever remove and the chance of breaking the latch was high. Before you think it was just user error installing them know that I've installed lots of keystones. The Cat6 keystones and Trendnet lc to lc keystones currently in this panel do not have this problem.

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.

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.

Does the job, is easy to install, and seems to be quality made.

Bought these to build out a home network and these mounted perfectly in a keystone wall cover and a 24 port switch patch panel. Coupled with a 50ft run then pass the signal through with no issues.
