The LC has become the preferred connector for transceivers with high rate applications because most manufacturers support LC interfaces and they are available from 10Mbps to 10Gbps applications.LC connectors can be spliced and installed in the field using the same methods as SC and ST, while MT-RJ connectors require two fibers to be installed/spliced at the same time, which could harm the overall performance.MT-RJ connectors are difficult to clean due to the alignment pins. It is easier to clean LC connectors because they allow to use traditional fiber cleaning.Instead, MT-RJ ferrules are made from plastic and use metal pins to align the fibers. LC connectors deliver better Insertion Loss and Return Lossīecause its 125um ceramic ferrule offers a better connector-adapter-connector mating quality.Two LC connectors can be put together into a duplex assembly and occupy the same space as a single SC would. It is made from plastic and holds a single fiber into a ceramic or zirconia ferrule. LC connector is a small, low insertion and loss connector that was created by Lucent Communications in order to suit their customers’ needs. AMP used the MT ribbon connector design as an inspiration to create an inexpensive MT connector that could hold two fibers into a plastic ferrule. MT-RJ connector was developed by AMP and at its moment was advertised as the ultimate SFF connector. In the late 90’s different types of SFF connectors were developed, but just two of them succeeded until the current days: MT-RJ and LC. SFF connectors help reducing deployment costs and saving floor space for cables and equipment in fiber optic installations because they make it possible to put several fiber connections in the same space. Small Form Factor (SFF) connectors were created as a solution.
Using big connectors such as ST and SC increased floor use which caused higher installation costs and made it difficult to expand connections. Local Area Networks (LAN) and building backbones opened an issue about fiber connectors’ size.The growing deployment of fiber optics in Its body and ferrule are made of plastic and it has male and female versions that stay in place with metal pins. It holds two fibers at the same time in a small body. The below chart lists the commonly used color-codes.MTRJ is a Small Form Factor duplex connector. It's important to use the proper connector on the proper cable because of different optical core and ferrule sizes. They were designed by Panduit™ to offer a quick connection option when wiring buildings with fiber.Ĭommon applications: building wiring, networkingįiber optic connectors are specific to either multimode or single mode fiber optic cable and the connector's color typically designates compatibility. They look and feel similar to a traditional RJ45 connector.įJ (fiber-jack or opti-jack) connectors are similar to MTRJ connectors in size and scope. MTRJ (mechanical transfer registered jack) connectors are typically used for duplex multimode connections and are increasing in popularity due to their small form factor and easy connection/disconnection. Similar to the ST connector, FC connectors provide a secure, locking connection that delivers a precise optical wave.Ĭommon applications: video over fiber electronics, test equipment, telecom applications ST (straight tip) connectors provide a secure, spring-loaded locking connection that's similar to the BNC connectors historically used in AV applications.Ĭommon applications: networking, datacom applicationsįC (ferrule core) connectors are rapidly decreasing in use thanks to the rise of LC connectors. Their size makes them easier to terminate, but it also limits their application in modern, size-sensitive electronics.Ĭommon applications: networking, multiplexers, media converters, demarc wiring, telecom applications SC (subscriber or standard) connectors are larger and less expensive than LC connectors. They've become the standard for SFP modules and most modern network electronics.Ĭommon applications: networking, SFP modules, AV over fiber extenders, high-density connection applications LC (Lucent) connectors are one of the smallest formats of connector.

The below guide explores the connectors commonly used in audio-visual, networking, broadcast and other low-voltage applications. Fiber optic connectors are available in a variety of formats depending on the cable type and connection style.
