Lc Vs Sc Fiber Optic Connector

Lc fiber connector adapter and cable assemblies.

Lc vs sc fiber optic connector.

Sc is a push pull connector while lc employs a latch as opposed to sc s locking tab. With the rapid development of fiber networks fiber connectors have become an essential assembly to cater for high performance fiber optic system. 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. See the below images for better understanding.

Sc is arguably the most common type of fiber optic connector used today. The main differences among types of connectors are dimensions and methods of mechanical coupling. 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. The sc connector has a ferrule of 2 5mm while the lc features a 1 25mm ferrule which exactly half of the sc size.

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. Connectors upc and apc polish. 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.

While being faster and easier to operate is an advantage the main draw of lc is its small size. Available in simplex or duplex versions lc connectors can be used with both single mode and multi mode cables. 6 steps help to choose right fiber optic patch cable. Fiberstore offers a variety of high speed fiber optic patch cables with lc sc st fc etc.

Lc is half the size of sc. Typical connectors are rated for 500 1 000 mating cycles. The fundamental difference between lc and sc fiber optic connectors lies in size and connection handling. Actually one sc adapter is exactly the same size as a duplex lc adapter.

Considered by some to be the modern replacement of the sc connector. 3m when it comes to cost comparison sc connectors can be manufactured at a lower price so they cost less than lc connectors. 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. Developed by lucent technologies the lc connector otherwise known as a lucent connector measures about half the size of an sc connector.

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. A variety of optical fiber connectors are available but sc and lc connectors are the most common types of connectors on the market.
