Amphenol ST fiber optic connector for reliable singlemode and multimode network connections

ST Connectors

Amphenol’s ST and  STII connectors utilize a bayonet  style mating  concept  to  provide a secure, robust coupling  mechanism. The enclosed spiral slotted coupling nut allows easy insertion in densely packed patch panels. The ST connector has been used extensively in telecom, data premise installation, and test lab applications.   Special attention has been given to every ST performance parameter, increasing product repeatability and exceeding industry standards.    The ST connector is available with a plastic or die cast body with a ceramic or stainless steel ferrule.

    • The ST connector body and coupling nut are precision molded with a flame retardant polymer for a durable and light weight product

    • The STII connector body and coupling nut are precision zinc die cast and nickel plated for superior strength and corrosion resistance

    • High precision zirconia ferrules minimize insertion loss and return loss values

    • Available in singlemode and multimode versions

    • Available with 900μm, 2.0mm, or 3.0mm, 45/90 degree, and flex boots

    • Stainless steel ferrules also available on both the ST and STII connector

  • Insertion Loss: 

    ≤ 0.15dB Typical Singlemode

    ≤ 0.25dB Typical Multimode

    Return Loss:

    Ultra (UPC) > 55dB

    Durability:

    < 0.2dB change, 500 Mating Cycles

    Temperature:

    <0.3dB change, -40 to +85°C
