Phosphor Bronze Sleeves


Metal split sleeves are used in adapters for aligning the connector ferrule. They are manufactured for both singlemode and multimode applications. The high quality phosphor bronze material delivers a spring-like property which ensures a strictly controlled withdrawal force of 200 to 600 grams. Tolerance specifications are also well controlled resulting in a typical insertion loss of 0.1dB* or less. Sleeves are available in SC, FC, ST, D4, MU, and LC style.
