ST Standard Plastic Fiber Optic Connectors

We offers the ST Standard Plastic Fiber Optic Connectors, these ST Connectors are strictly tested during the production and feature the good price and excellent quality. Our ST fiber connectors and related products follow the IEC 61 754-2 standards.They have different color to choose:

The ST Fiber Optic Connector products and related ST fiber products are widely used in today’s telecommunication filed including both long haul and local network applications. ST connector is one of the fiber connectors that dominate the market today.

ST fiber connector is with twist-lock bayonet coupling, its 2.5mm keyed ferrule meet the durability and repeatability requirement for the fiber optic links. Typical ST fiber optic connector use metal housing, but plastic housed ST connectors are also used sometimes. ST connectors are generally three types: single mode ST/UPC fiber optic connector, single mode ST/APC fiber optic connector, multimode ST/UPC fiber optic connector.
