G657 single mode fiber

product description

G.657 single mode fiber has better resistance to macro bending property, Is a kind of the low water peak fiberwhich is not sensitive to bending, can make full use of O + S + C + L band (1260 ~ 1625 nm) to transmission. Having lower polarization mode dispersion (PMD), can meet the requirements of high speed and long distances. G.657 single mode fiber has two categories: G657 A1 and G 657 A2, mainly used for short fiber optic cable with special purpose, great performance on O + S + C + L band; FTTX high speed light routing; can also be used for cable which require a small bending radius.

production standard

Conforms to the ITU - T suggest G657 D and IEC 60793-2 - 50B1. 3 kind of optical fiber technology standard and national standard GB/T 9771.1

Product feature(G.657A2)

Excellent resistance to bending performance from 7.5 to 15 mm bending radius,

Low attenuation is applicable to O + S + C + L band work requirements

Fully compatible with other G652 single mode fiber

Low polarization mode dispersion (PMD) meet high speed and long distances

Precise geometry to ensure that the low welding loss and high welding efficiency
