Fiber type：G.652D
FUTONG G.652D single-mode fiber fits the operation over the full optical spectrum from 1280nm to 1625nm by suppressing hydroxyl (OH-) absorption near 1383 nm, which subsequently activates the 100nm wavelengths.
With excellent performances of low attenuation, low dispersion and more steady, FUTONG G.652D single-mode fiber is widely utilized in high-speed optical communication transmission networks including of access network, metro network besides the long-haul network.
