Profile: Fibercore Ltd specializes in providing fiber products. The SM1500 series fibers are offered with a range of numerical apertures from 0.20 to 0.30. The high NA of these fibers reduces the bend-induced loss to levels far below standard telecommunication fibers allowing them to be used in diameters of 10mm or smaller. The high germania content of these fibers also considerably enhances their photosensitivity, making them ideally suited to the fabrication of certain types of fiber bragg gratings. Singlemode transmission from 450 nm to 1600+ nm is designed for wavelengths ranging from 488 nm to 1600+ nm, our specialty singlemode fibers are engineered to work in applications ranging from biotechnology, medical & laser delivery, through telecommunciations, to sensors and tethered/payout applications. HiBi is a singlemode, polarization-maintaining optical fiber designed for interferometric & polarimetric sensors, integrated optics and coherent communications. The characteristic bow-tie stress-applying parts, or SAPs, act like opposing wedges to generate the optimum stress distribution within the fiber.
