Many applications that originally used bulkier, more expensive connectors have converted to modular connectors.
The convenience of prior existence for designers and ease of use led to a proliferation of modular connectors for many other applications. The Federal Communications Commission (FCC) mandated in 1976 an interface registration system, in which they became known as registered jacks. Modular connectors were originally developed for use on specific Bell System telephone sets in the 1960s, and similar types found use for simple interconnection of customer-provided telephone subscriber premises equipment to the telephone network. This is the common crimp-type plug, of the same kind pictured above crimped onto a cable (with molded sleeve).Ī modular connector is a type of electrical connector for cords and cables of electronic devices and appliances, such as in computer networking, telecommunication equipment, and audio headsets.
