Welcome To Twentsche (Nanjing) Fibre Optics Ltd. (for short: TFO)！
Based on the optimum coated layer design, TFO MiniTM Premium WideBand Plus optical fibre keeps the cladding diameter unchanged but with coated diameter dramatical reduction. This product still retains the same and outstanding properties as ITU-T G.652.D and IEC 60793-2-50 type B1.3 fibre with traditional coated diameter 245μm. And with zero water peak, low attenuation and excellent uniformity, low chromatic dispersion and PMD,superior and stable geometrical size control level, this full spectrum fibre is applicable to transmission system operating over the entire wavelength from 1260nm to 1625nm.
TFO MiniTM Premium WideBand Plus optical fibre supports higher density and smaller diameter cables which can improve duct utilization and save resource, widely used in the applications of high count fibre cable, microcables. etc.
