The Standard Connector also known as Subscriber Connector was one of the first connectors to hit the market following the advent of ceramic ferrules. Sometimes referred to as the ‘square connector’ the SC has a push-pull coupling end face with a spring loaded ceramic ferrule. Initially intended for Gigabit Ethernet networking, it was standardized into the telecommunications specification TIA-568-A in 1991 and slowly grew in popularity as manufacturing costs came down.
Due to its excellent performance it dominated fiber optics for over a decade with only the ST rivalling it. Thirty years on, it remains the second most common connector for polarization maintaining applications. The SC is ideally suited for datacoms and telecoms applications including point to point and passive optical networking.
SC is a snap-in connector also with a 2.5 mm ferrule that is widely used for it’s excellent performance. It’s a connector that latches with a simple push-pull motion. It is also available in a duplex configuration.
For bi-directional transmission, two fiber cables and two SC connectors (Dual SC) are used. SC is specified by the TIA as FOCIS-3.
SC Connectors provide non-optical disconnect terminations in a push-pull coupling mechanism, has been tested to the rigorous Telcordia GR-326-CORE. Molex SC connectors are available with a metal plug one-piece design or polymer plug tunable design, with either a simplex, duplex fixed or duplex floating, Fibre Channel compliant, housing style. All versions utilize pre- radiused precision ceramic ferrules and one-piece body design that provide quick and economical terminations, both in factory, and in-the-field settings.
Connectors are available for single mode, multimode and Angle Polished (APC) applications. APC connectors are designed with a uniquely precise, pre-angled and pre-radiused Angled Physical Contact (APC) ferrule. The result is an APC connector with superior insertion and return loss performance.
