The global fiber optic connector market is expected to reach USD 5.9 billion by 2025, according to a new report by Grand View Research, Inc. The business of global fiber optic connectors have achieved big success over the past few years. You can check the detailed specification of the above four fiber optic connectors on the below table. The typical insertion loss of the FC connector is around 0.3 dB. Multimode versions of this connector are also available. The key is also used for repeatable alignment of fibers in the optimal, minimal-loss position. This high-precision, ceramic ferrule connector is equipped with an anti-rotation key, reducing fiber endface damage and rotational alignment sensitivity of the fiber. It is mainly used in fiber optic instruments, singlemode fiber optic components, and high-speed fiber optic communication links. The FC fiber optic connector has become the connector of choice for singlemode fiber. Some manufacturers of fiber AV equipment also use SC connectors in conjunction with their optical emitter and detector devices. Like the LC connector, this is also a push-pull design and is also commonly used in patch panels that act as the connector interface between the main field cable and smaller patch cords connected to the fiber transmission equipment. The SC fiber optic connectors are common in singlemode fiber optic telecom applications and analog CATV. The LC connector is smaller than all other connectors and is a push-pull design connector. These SFP devices are now becoming very common in Pro AV applications for such products as HDMI, DVI, audio, optical distribution amplifiers, optical/electrical/optical (OEO) switches, and so forth. It is used in conjunction with small form pluggable (SFP) optical transceivers. But LC connector does not stand for Lucent Connector. Besides, it has good strain relief and good, but not exceptional attenuation characteristics.ĭeveloped by Lucent Technologies, the LC fiber optic connector has become the ubiquitous fiber optic connector for telecom applications. It is relatively easy to terminate in the field. The insertion loss of the ST connector is less than 0.5 dB, with typical values of 0.3 dB being routinely achieved. It is available in both multimode and singlemode versions. It has become the de-facto standard in the security market and is commonly used in the AV market on such products as HDSDI, RGB/DVI, and others. This simplex fiber connector evolved from previous designs and was finally introduced by AT&T in the mid-late 1980s. ![]() One most common of fiber optic connectors is the ST connector. In this passage, we would mainly give brief introduction to the four most common fiber optic connector types. They have been widely used in the termination of fiber optic cables, such as fiber optic pigtail, fiber optic patch cables and so on. All fiber optic connectors have four basic components, which are the ferrule, connector body, cable, and coupling device. Each one has its own advantages, disadvantages, and capabilities. It is no longer recommended by TIA.įor help identifying older legacy fiber optic connectors, see the Fiber Optics Association Connector Identifier web page.Ĭheck out Leviton's full range of fiber connectors, and see our previous blog post on terminating fiber connectors in the field.The common fiber optic connector types include ST, SC, FC, LC, MU, E2000, MTRJ, SMA, DIN as well as MTP & MPO etc. While it was once the most popular connector for multimode networks, it is now a legacy connector and is difficult to use in high density duplex applications. The Straight Tip connector uses a twist lock coupling and a 2.5 mm ferrule. The Subscriber connector is a push-pull connector with a 2.5 mm ferrule and is keyed for standard A/B duplex polarity. MTP® is a high performance MPO connector, trademarked by USConec Ltd. The MPO or multi-fiber push-on connector can accommodate up to 32 fibers and is keyed for array polarity. It has a 1.25 mm ferrule and is half the size of an ST or SC connector. The Lucent connector or "little connector" is a small form factor latching connector and is keyed for standard A/B duplex polarity. Here's a quick look at the four most common connector types: While you may encounter more legacy connectors in existing enterprise networks, such as ST or FC, you'll likely be choosing between an LC or MPO connector moving forward. However, this list has consolidated recently based on trends in transceivers. There are quite a few connector types available, including LC, SC, MPO, ST, FC. The type of fiber connector you choose ultimately will be influenced by the fiber transceiver interface. ![]()
