Fibershack - LC Coupler Tin - 20 Pack - Single Mode LC Fiber Couplers Set. LCUPC Fiber Adapters are Pre-Cleaned & Extend LCUPC Optical Cables. Connects SM Simplex or Duplex Cables

nice tin of connectors. just what you need for connections. I use these in a training class on Fiber Maintenance, and the students tend to go through them. Seems to be quality connectors and will do what I need them to.

I needed these couplers fast and was able to get these next day. Saved the day. Great product too.

Great Product and Packaging

Good couplers, nice little storage case, and a bonus of some extra dust caps.

These work well and are quite versatile. The metal spring clips hold these connectors tightly in a junction box, but can just as easily be an inline connector to lengthen a cable run. I use these to lengthen my Verizon fiber optic cable. It terminated in my bedroom, and have used this to feed an extension through the wall and floor into my office where it is more suitable. Speed is not affected - the speed tests were taken prior and post installation. I have not used anything like this before, but it works as I expected it to, and I am very happy that there is no loss in speed with the connector. All good, and nothing I could find wrong, so 5 stars.

Product is as advertised and very good quality. Order arrived before expected and in great condition. I will definitely use FiberShack in the future for my fiber needs and would recommend their products.

I need to extend the fiber cable coming into my house and these worked like a champ.

This is just what we needed. It arrived quickly and was just as described.
