G.654E Single-mode fiber with ultra-low loss and zero dispersion relation
product description ：
Ultra-low loss cut-off wavelength-shift single-mode fiber (G.654E) is a type of fiber with ultra-low loss and larger effective area, which can reduce the number of repeaters, reduce nonlinear effects, and achieve long-distance, multi-wavelength high-speed transmission.
operative norm ：
It meets and exceeds the requirements of ITU-T G.654E and IEC 60793-2-50 B1.2 fiber optic technical specifications.
Product features:
The 1550nm window attenuation is reduced to less than 0.170, which can meet the requirements of ultra-long distance transmission without relay; the large effective area can effectively reduce the nonlinear effect of optical fiber transmission, and achieve long distance error-free transmission.
Product Application:
Suitable for long distance land transmission and submarine cable.
