From left to right: FC, LC, SC, and ST
Fiber optic cables utilize a few different connectors that can be used to terminate the cable. While they do bear some similarities, each kind has a different enough size and shape that they are not interchangeable. When preparing any fiber-related equipment for installation, it is important to make sure the cables are equipped with the right connectors for the job.
FC is an older fiber optic connector currently being phased out of industry standards. While single mode cables still use FC, it is unusual to see them on multimode cables. FC connectors take longer to unplug compared to newer fiber optic connectors due to their threaded screw-on design. Additionally, the more complex design and use of metal make them more costly to manufacture. Despite those downsides, FC still sees some use since those threads allow it to remain secure when used on moving machinery.
LC was designed as a push-pull connector that locks in place with a latch. While being faster and easier to operate is an advantage, the main draw of LC is its small size. Being about half the size of other fiber optic connectors, LC can be used on devices that would otherwise have too little room to support a fiber optic connection.
SC is arguably the most common type of fiber optic connector used today. Designed to be simple to use and inexpensive to produce, SC uses a push-pull design similar to LC but utilizes a locking tab instead of a latch to secure the unit. The cost-effective design of SC makes it a popular choice with industries that frequently use fiber cables, such as telecom and datacom.
ST uses a design similar to FC but instead of threads, it uses a locking mechanism similar to

Modern telephone cords have been in use for a long time, with little change since their invention in the 1970s. Finding phone cords in the store can be tricky today; many stores have stopped carrying telephone cables since so many people only use cell phones now. This rings especially true for coiled handset cords. With these cables becoming rarer, sometimes it is better to repair rather than replace them. Other times, users may just need a cable not available in a standard length.
There is a bit of variation with different connectors available, as well as different wiring schemes (called pinouts) for the smaller wires inside the main cord. This guide will cover how to attach a connector to the end of bare phone cable and the difference between wiring pinouts.
Step 1: Gathering the Supplies
There are a few simple supplies that will be needed for an installation or repair. The key components are the bare phone cable and the correct type of connectors. There are three main types of connectors that can be used. RJ12 is the most common, being used on flat line cords that connect the base of a telephone to the wall. RJ11 is an older version of RJ12, and they are the same size. The difference is that RJ11 uses four internal wires (called conductors) while RJ12 uses six. RJ12 is backwards compatible with RJ11, but RJ11 will not work with RJ12.
