Welcome To Twentsche (Nanjing) Fibre Optics Ltd. (for short: TFO)！
TFO PWPTM Premium WideBand Plus fibre exceeds the specification of ITU-T G.652.D and IEC 60793-2-50
type B1.3 fibre. 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.
It is applicable to all types of optical cables including ribbon fibre cable, slotted core cable, standard loose
tube cable, central-tubed cable, ADSS, OPGW and tight- buffer cable etc, and widely used in Ethernet,
Internet, Long-haul trunks communication, metropolitan area network and WDM system etc.
