Its light weight, compact and robust structure, combined with a low-friction HDPE outer sheath, makes the cable perfectly suitable for installation in ducts by pulling, floating or air-blowing, or on facades or aerial between telecom poles over limited distance (max. 60m . There are 19 different single mode optical fiber specifications defined by the ITU-T, among which G. 652 fiber is the most commonly used. 652 is an international standard that describes the geometrical, mechanical, and transmission attributes of a single-mode optical fibre and cable, developed by the Standardization Sector of the International Telecommunication Union (ITU-T) that specifies the most popular type of single-mode. The optical fibres are made of a high grade doped silica core surrounded by a silica cladding. They are coated with a dual layer, UV cured acrylate based coating. This enhanced single mode fibre provides improved performance across the entire 1260 nm to 1625 nm wavelength spectrum due to its low. The Soft Tube Cable (STC) is a non-metallic, longitudinal water-protected outdoor fibre optic cable, designed for the construction of optical infrastructure networks (back-bones, distribution and access). It contains Soft Tubes, for fast and easy access to the fibres (without tooling), to avoid the. GL FIBER® provides the whole series of SMF products that meet and even excel the requirements of standards on performance indicators.
