LC vs SC Connection Handling - LC connector features with latch structure and designs with a locking tab to secure the cable, whereas SC features with push-pull structure and locks in place with a latch to secure the cable.Ģ. Its small size allows twice the port density on a faceplate than an SC connector does. The diameter of the LC is 1.25mm while the SC is 2.5mm, thus LC is more friendly to high-density applications. LC vs SC Size - LC is smaller than SC, which is half the size of it. What is the difference between LC and SC fiber optic connectors?
They are typically applied in high-speed data center and LAN applications.įrequently Asked Questions About Fiber Connectorsġ. MTP connectors are used interchangeably with MPO. An MTP/MPO connector has a capacity of 2-fiber, 4-fiber, 8-fiber, 12-fiber, 24-fiber, even up to 72-fiber.
The other is the evolution of LC to MTP/MPO, which aims not only to achieve space-saving but also fulfill the multi-fiber application requirement. The one is the development from FC, ST, SC connector to LC, which aims to achieve space-saving and miniaturization. The development of fiber connectors can be divided into two stages. ST Connector Structure Fiber Connector Types - MTP/MPO ST is typically used in multimode datacom, however, it has also been replaced by SC or LC connectors. Same as SC and FC, the ferrule diameter of the connector is also 2.5mm. Besides, because of the spring-loaded structure, ST fiber optical connector takes a lot of energy to push and twist the connector. Similar to the FC, the index tab must be carefully aligned with a slot when insertion. ST optical connector features a bayonet structure. Multimode LC Fibers & Single-mode LC Fibersĭuplex OM4 multimode fiber with LC connectorsĭuplex OS2 single mode fiber with LC connectors It has been widely used in both single-mode and multimode SFF (Small Form Factor) transceivers and gradually replaced SC due to its smaller size. The LC connector has dominated the market. The small size contributes to increasing the density of fiber connectors housed in optical fiber wiring frames. The ferrule diameter of the FC is only 1.25mm, which is half of SC and FC connectors. LC fiber connector adopts a modular jack latch structure, which has a great advantage of ease-operation. However, it has been gradually replaced by SC and LC, which provide the equivalent performance of FC but get a faster connection speed yet.įC Connector Structure Fiber Connector Types - LC Same with the SC, the ferrule diameter of the LC fiber connector is also 2.5mm.įC connector is generally used in datacom, telecom, measurement equipment, single-mode lasers, etc since it was introduced. It must be done very carefully when aligning the key, furthermore, there is also the risk of scratching the fiber end face when inserting the ferrule into the jack. The screw installation of the FC is a little more complicated than the push-pull SC fiber connector. SC Connector Structure Fiber Connector Types - FCįC (Ferrule Connector) features a round screw structure. With the advantages of low price, easy push-pull operation, low insertion loss, good compression strength, etc, it has been widely used since the 1990s with only the ST competing with it. SC is usually used in Gigabit Ethernet networks, datacom, and telecom applications. There is a spring inside the flange and if you hear the springs twanged when you insert the connector into the flange, that means the connector has been properly connected. SC fiber connector stands for square fiber optical connector, which features a square push-pull structure.
Next, this article will introduce the widely used fiber connector types in the past and present including FC SC LC ST and MTP/MPO connectors one by one.įiber connector types of LC, SC, FC, ST, MTP, MPO In today’s data center applications, small, simple, and multi-fiber fiber connectors have gradually replaced larger and complex types, achieving higher density fiber ports per unit of rack space. A better connector loses very little light due to reflection or misalignment of the fibers.Ī good fiber connector can be measured as the following factors: However, the widely used types are about a dozen of fiber optic connectors, which can be divided into single-fiber, duplex fiber connectors (such as FC, LC, SC), and multi-fiber connectors (such as MTP/MPO).įiber connector is associated with the reliability and performance of optical transmission systems. According to the estimating, there are hundreds of different fiber connector types on the market. The fiber connector is a kind of detachable passive optical component used in the connection between fiber to fiber, the light source to the fiber, and fiber to the detector to achieve the light maximize coupling to the receiving fiber.
