Lc Vs Sc Fiber Optic Connector

Lc is half the size of sc.

Lc vs sc fiber optic connector.

The lc connector uses a 1 25mm ferrule with a retaining tab mechanism. Developed by lucent technologies the lc connector otherwise known as a lucent connector measures about half the size of an sc 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. The main differences among types of connectors are dimensions and methods of mechanical coupling.

Typical connectors are rated for 500 1 000 mating cycles. Sc is a push pull connector while lc employs a latch as opposed to sc s locking tab. 3m when it comes to cost comparison sc connectors can be manufactured at a lower price so they cost less than lc connectors. 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 difference is that single mode lc connectors have it in apc upc polishing type while multimode lc fiber connectors have upc polishing only. With the rapid development of fiber networks fiber connectors have become an essential assembly to cater for high performance fiber optic system. Its introduction was less successful in part due to initially high license fees from inventor lucent corporation. Connectors upc and apc polish.

Fiberstore offers a variety of high speed fiber optic patch cables with lc sc st fc etc. See the below images for better understanding. 6 steps help to choose right fiber optic patch cable. The fundamental difference between lc and sc fiber optic connectors lies in size and connection handling.

The sc connector has a ferrule of 2 5mm while the lc features a 1 25mm ferrule which exactly half of the sc size. Sc is arguably the most common type of fiber optic connector used today. Available in simplex or duplex versions lc connectors can be used with both single mode and multi mode cables. 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.

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. While being faster and easier to operate is an advantage the main draw of lc is its small size. 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. Due to the smaller size lc is more commonly used in offices and data centers where there are clusters of fiber optic cables.

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. Actually one sc adapter is exactly the same size as a duplex lc adapter.
