953 Series ST Connectors Amphenol’s 953 Series fiber optic ST and ST II 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. Features/Benefits • • • • • • 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 boots Stainless steel ferrules also available on both the ST and ST II connectors Specifications Insertion Loss: ≤ 0.15dB typical, singlemode ≤ 0.35dB typical, multimode Return Loss: Ultra (UPC) Durability: ≤ -55dB* < 0.2dB change, 500mating cycles Temperature:
