Molex has recently introduced Polymicro flame retardant FR fiber that meets UL 94 V-0 flame retardant specifications. The fiber uses carrier-grade single-mode fiber or multimode fiber with 50 micron and 62.5 micron step index with 125 micron outer diameter and 250 micron sheath, supporting excellent dimensional control and tight tolerances, operating temperature range -40 To 100 degrees Celsius. Molex said that the jacket of the fiber can be stripped like a conventional acrylate jacket. They also offer different fiber and sheath sizes for different jacket materials. The core diameter can range from 50 microns to 600 microns and is designed to be customizable, including fiber type, termination type and jacket material. The PolyMicro business was acquired by Molex in August 2007 and was originally located in Phoenix, Arizona, USA. Polymicro's business is mainly quartz capillary and special fiber, capillary components, quartz fiber connectors, etc., mainly in the fields of medicine, fiber laser processing and other fields.
