  ST CONNECTOR
Model:ST
ST Fiber Optic Connector features a bayonet locking mechanism to reduce the risks of accidental disconnection of fiber connections. This connector is comprised of a Nickel plated Brass body and a Ceramic ferrule/spring/crimp barrel assembly plus a crimp over sleeve with rubber boot. These connectors are suitable for, 900μm and 2-3mm cables. The connector is precision made and manufactured to demanding specifications. The combination of a Ceramic ferrule with precision metal housing provides consistent long-term mechanical and optical performance.
