Lc Vs Sc Fiber Optic Connector

The fundamental difference between lc and sc fiber optic connectors lies in size and connection handling.

Lc vs sc fiber optic connector.

Connectors upc and apc polish. Lc fiber connector adapter and cable assemblies. Developed by lucent technologies the lc connector otherwise known as a lucent connector measures about half the size of an sc connector. Typical connectors are rated for 500 1 000 mating cycles.

Sc is arguably the most common type of fiber optic connector used today. The lc connector uses a 1 25mm ferrule with a retaining tab mechanism. They use a mating adapter to mate the two connector ferrules that fits the securing mechanism of the connectors bayonet screw on or snap in. 3m when it comes to cost comparison sc connectors can be manufactured at a lower price so they cost less than lc connectors.

Fiberstore offers a variety of high speed fiber optic patch cables with lc sc st fc etc. Sc is a push pull connector while lc employs a latch as opposed to sc s locking tab. Most fiber optic connectors are plugs or so called male connectors with a protruding ferrule that holds the fibers and aligns fibers for mating. There are various fiber connector types in the market such as lc st sc mpo mtp and so on among which sc is one of the most commonly used fiber connectors.

Considered by some to be the modern replacement of the sc connector. A variety of optical fiber connectors are available but sc and lc connectors are the most common types of connectors on the market. See the below images for better understanding. And generally speaking the difference between lc and sc fiber optic connector lies in the size the handling and the connector history which will be discussed respectively in the following text.

Actually one sc adapter is exactly the same size as a duplex lc adapter. The main differences among types of connectors are dimensions and methods of mechanical coupling. Its introduction was less successful in part due to initially high license fees from inventor lucent corporation. Due to the smaller size lc is more commonly used in offices and data centers where there are clusters of fiber optic cables.

Available in simplex or duplex versions lc connectors can be used with both single mode and multi mode cables. Lc is half the size of sc. While being faster and easier to operate is an advantage the main draw of lc is its small size. The sc connector has a ferrule of 2 5mm while the lc features a 1 25mm ferrule which exactly half of the sc size.

6 steps help to choose right fiber optic patch cable. The difference is that single mode lc connectors have it in apc upc polishing type while multimode lc fiber connectors have upc polishing only.
