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

This is a good LC connector Spicer I actually use it to connect two ends together to keep them clean. I don’t use it to extend fiber, but just to keep the ends protected instead of having to covers that are hard to find.

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.

Worked as expected

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.

Great Product and Packaging
