D4 Connectors

The D4 Connector is an older generation single-mode fiber optic connector that is spring loaded and keyed with a 2.0mm precision zirconia ferrule. The screw-on mechanism is a threaded nickel-plated brass body. The key prevents opposing ferrules from touching while mating. D4 Connectors are available with a APC (Angled Physical) ferrule endface or a PC (Physical Contact) pre-dome ferrule endface. There is also a crimp free or crimp style version. Applications for the D4 Connector include telecom networks, WANs (Wide area networks), and LANs (Local area networks).
