POTEL®CONEXESS® G655 fiber has excellent attenuation, polarization mode dispersion and dispersion index, and is suitable for long-distance and high-speed transmission systems.
- G655 fiber fully optimizes the attenuation and dispersion characteristics in the 1550nm window, meeting the transmission requirements of multi-channel dense wavelength.
- Division multiplexing {DWDM) and high output power erbium-doped fiber amplifiers (EDFA) in the C-band and L-band working windows; capable of high-speed long-distance transmission without dispersion compensation; its excellent attenuation and dispersion characteristics make.
- It suitable for long-distance and high-speed transmission systems. Suitable for various cable structures, including fiber ribbon cables, loose tube layer-stranded cables, skeleton cables, central tube bundle cables, etc.
• Suitable for high-speed transmission in the C-band {1530-1565nm) and L-band (1565-1625nm)
• 1500nm and more sensitive 1625nm window has low bending additional loss
• Good coating protection and excellent stripping performance
• Precise geometric parameters ensure low fusion loss and high fusion efficiency
• Large effective area ensures good system transmission performance.
