G.655 single mode fiber cable

Optimize the attenuation and dispersion of 1550nm working window Meet the C / L wave band DWDM transmission requirements

Applicable to the C wave band (1530-1565nm) and L wave band(1565-1625nm) high-speed transmission

Low attenuation, chromatic dispersion, polarization mode dispersion, zero-dispersion rate

Coating protective ,superior stripping 

1550nm and more sensitive to 1625nm window has a lower bendingexcess loss
