LASSARD produces quartz optical fibers and fiber optic cables based on them: The range includes fibers with a core diameter from 4 to 1000 µm, length up to 1 km, single-mode and multimode; with preservation of polarization; with acrylate, aluminum and copper coating; with double cladding (DC). The diameter of the reflective cladding of the fibers is 110 µm to 1100 µm, the protective coating is 140 µm to 1500 µm.
Optical cables based on passive quartz fibers doped with fluorine and coated with copper are used in environments with aggressive temperatures.
Optical fibers are used for making patch cords with lengths from 1 m to 50 m (up to 100 m on request) with SMA-905, D-80, FC and ST connectors. Possible types of fiber end polishing: FLAT, PC, UPC (APC polishing is optional).
