I recently got the Fibershack LC Coupler for fiber-optic work, and it's become a small but essential part of my toolkit. The tin is compact and keeps all 20 LC couplers neatly organized, making it super easy to grab what I need without rummaging through loose parts. It's ideal for keeping things clean during on-site installs or routine maintenance. These LC couplers are single-mode, simplex or duplex compatible, and come pre-polished and covered with dust caps—so they're clean and ready right out of the tin, which cuts down on prep time. They’re tested and meet industry safety and environmental standards like UL, IEC, RoHS—and that gives me confidence in their quality. What I liked: Tidy storage – the tin keeps couplers secure and easily accessible. Professional-grade components – pre-cleaned, polished, and dust-capped, so they’re plug-and-play. Reliable performance – works with both simplex and duplex LC patch cables.

VERY good product. Solid, and every one of them worked well!

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.

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.

Great Product and Packaging
