Lc Vs Sc Fiber Optic Connector

Lc fiber connector adapter and cable assemblies.

Lc vs sc fiber optic connector. Most fiber optic connectors are plugs or so called male connectors with a protruding ferrule that holds the fibers and aligns fibers for mating. Considered by some to be the modern replacement of the sc connector. Sc is arguably the most common type of fiber optic connector used today. Developed by lucent technologies the lc connector otherwise known as a lucent connector measures about half the size of an sc connector.

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. See the below images for better understanding. 6 steps help to choose right fiber optic patch cable. 3m when it comes to cost comparison sc connectors can be manufactured at a lower price so they cost less than lc connectors.

A variety of optical fiber connectors are available but sc and lc connectors are the most common types of connectors on the market. The sc connector has a ferrule of 2 5mm while the lc features a 1 25mm ferrule which exactly half of the sc size. Available in simplex or duplex versions lc connectors can be used with both single mode and multi mode cables. Due to the smaller size lc is more commonly used in offices and data centers where there are clusters of fiber optic cables.

With the rapid development of fiber networks fiber connectors have become an essential assembly to cater for high performance fiber optic system. Typical connectors are rated for 500 1 000 mating cycles. Fiberstore offers a variety of high speed fiber optic patch cables with lc sc st fc etc. Actually one sc adapter is exactly the same size as a duplex lc adapter.

While being faster and easier to operate is an advantage the main draw of lc is its small size. Connectors upc and apc polish. Lc is half the size of sc. The lc connector uses a 1 25mm ferrule with a retaining tab mechanism.

Its introduction was less successful in part due to initially high license fees from inventor lucent corporation. The main differences among types of connectors are dimensions and methods of mechanical coupling. 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. 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.

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. Sc is a push pull connector while lc employs a latch as opposed to sc s locking tab.
