In the late 1990s, there came a demand for small form factor (SFF) connectors to support high-density environments. This quick connecting bayonet design originally made ST connectors popular for campus, enterprise and military multimode networks, but because it does not support an angled polish (i.e., APC) preferred for today’s telco and FTTX singlemode deployments (you can read more about that here), its use has declined considerably over the past decade. It is a spring-loaded connector that looks very similar to the FC but uses a bayonet design instead of a threaded screw. While it was the most popular singlemode connector type for several years, due its higher cost, it has been widely displaced by other connector types.Ĭovered by TIA-604-2 (FOCIS-2), the ST connector type was introduced by AT&T in the late 1980s. Covered by TIA-604-4 (FOCIS-4), the FC uses an alignment key and is tightened firmly using a screw-like motion, which makes it popular for high vibration environments. Unlike the square plastic SC, the FC (ferrule connector) is a round threaded connector that uses a stainless-steel housing around the ceramic ferrule. It still likely remains the second most common fiber connector type for simplex and duplex applications. Available as simplex or duplex, the SC is covered by TIA-604-3 (FOCIS-3), and due to its excellent insertion loss performance and fast deployment, it dominated as the connector of choice well into the 1990s. It features a snap-in design that mates using a push-pull action with a spring-loaded ferrule. Developed by Nippon Telegraph and Telephone (NTT), the SC connector is easily recognized by its square shape. SC, FC and ST fiber optic connectors all feature a 2.5mm ferrule size and can therefore be mixed and matched using special hybrid adapters. Let’s take a closer look at the types you might come across and how they differ. These standard-compliant connectors are covered by EIA/TIA-604 Fiber Optic Connector Intermateability Standards (FOCIS). Thankfully you don’t need to know the ins and outs of all of these types of connectors since there are just a handful that make up the majority of what you might come across in today’s cabling plants. In fact, according to the Fiber Optic Association, in all there are about 100 different types of fiber optic connectors. Over the past several decades, the market has seen the introduction of various fiber optic connectors aimed at providing lower insertion loss performance, lower cost, higher density and/or easy termination. The first ferrules introduced in the 1970s were comprised of metal or a hard plastic, and then in the mid-1980s, the introduction of the ceramic ferrule improved alignment and allowed for lower insertion loss. Katie Hickey, a graduating senior from Carondelet High School in Concord, CA, and a future student at San Diego State University, participated in an all-female Engineering for Social Good class.Fiber optic connectors include plugs that feature a protruding ferrule that holds the fiber in place and an associated adapter for aligning and mating fibers to form a connection point.
