G.652/G.652.D | Product Standards
G.652/G.652.D low-loss single-mode optical fiber is suitable for various optical cable structures, including optical fiber ribbon cables, loose-tube stranded cables, skeleton cables, central bundle cables and tight-buffered cables.
Aoptke Cable has established stricter standards for various indicators of optical fiber products.
G.652/G.652.D | Product Features
• Significantly reduces the attenuation level of the entire band from 1260 to 1625nm, meeting the requirements of longer distance transmission.
• Superior optical properties meet the transmission requirements of high-speed DWDM and CWDM systems.
• Compatible with existing 1310nm transmission equipment.
• Good coating protection and excellent stripping performance.
• Precise geometric parameters ensure low splicing loss and high splicing efficiency.
