Company Profile

10KM 20KM 30KM 40KM 50.4KM G657A1 G657A2 Coating Glass Bare Optical Fiber

This new fashionalbe G657A1 G657A2 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.

we have all type of glass fibre optic you need.
