There is no return path or return channel. Simplex: Transmission mode in which data can only be transmitted in one direction. Duplex transmission is therefore also referred to as two-way transmission (as per DIN). Reflections are reduced to a minimum.ĭuplex: Transmission mode in which data can be simultaneously transmitted in both directions. Grinding the fiber endface at an angle - usually 8°- means that reflected light is no longer propagated. Some fiber-optic connectors are available not only as a PC (Physical Contact) but also as an APC variant (Angled Physical Contact). Depending on the type and size of the connector housing, one or more ferrules can be accommodated in a single connector.Ĭonnector technology for optical fibers (OF): The expanded beam ferrule of the 3M ™ Expanded Beam Optical (EBO) Latch Connector is currently available in the 12-fiber multimode and singlemode versions and will be available in a 16-fiber multimode and singlemode variant in the future. In combination with high-quality cables, they are primarily used in harsh environments.ģM ™ Expanded Beam Optical (EBO) Latch Connector E-2000 ® connector, PC and APC.įerrule: Zirconia-ceramic, Ø 2.5 mm Expanded beam connectorsĭue to the optical expansion of the beam, expanded beam connectors are less sensitive to contamination than conventional fiber-optic push-on connectors. Design: Multimode & singlemode, normal and oblique cut. It possesses a push-pull locking mechanism and a self-closing dust protection flap. The E-2000 ® connector is an optical fiber push-on connector in compliance with international standard IEC 61754-15. APC connectors are preferentially used for singlemode cables.įerrule: Zirconia-ceramic, Ø 2.5 mm E-2000 ® connector This makes it possible to achieve a higher return loss. The light that is reflected here is no longer capable of propagation. The SC/APC push-on connector has an oblique, polished ferrule front face (8° or 9°). Versions: Multimode & singlemode, normal and oblique cut. The SC is an optical fiber push-on connector in compliance with DIN standard IEC 61754-15 for applications in the telecommunications sector, datacenters, LAN cabling and for connecting active components. MTP ® is a registered trademark of US-Conec Ltd. The MPO push-on connector is often referred to as an MTP ® connector. It is a push-on connector for multi-fiber cables consisting generally of 6, 8, 12 or 24 fibers. The abbreviation MPO stands for “Multi-fiber Push-on Connector”. LC connector (PC and APC).įerrule: Zirconia-ceramic, Ø 1.25 mm MPO/MTP ® connector The new generation of LC Compact connectors has a compact end housing which perfectly protects the fibers and permits reliable strain relief for the various cable types. The LC is a small-form-factor connector system for optical fiber cabling in compliance with the standard DIN EN 61754-20. The list below provides you with an overview of the commonly used connectors. Optical fiber cables can be equipped with a variety of connectors. Experienced professionals & entry-level applicants.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. 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.
