G655 single mode fiber
product description
G655 single mode fiber has the minimum window dispersion in 1550 nm and have a moderate amount of dispersion, meet the transmission requirements for Dense WaveLength Division Multiplexing of C wave band (1525~1565nm) and L wave band(1565~1625nm). can satisfy the high output power of erbium-doped fiber amplifier (EDFA) and DWDM system's requirements, could be used in high speed single/channel long digital transmission system with no dispersion compensation.
Production
Conforms to the ITU - T suggest G. 655 D kind of optical fiber technology standard and national standard GB/T 9771.1
Product feature
Suitable for high speed transmission of C band (1525 ~ 1565 nm) and L band (1565 ~ 1625 nm)
Good coating protect, superior stripping performance
Low attenuation dispersion polarization mode dispersion and zero dispersion slope fully meet the system transmission requirements
Precise geometry to ensure that the low welding loss and high welding efficiency
1550 nm and more sensitive 1625 nm window has low bending additional loss
