ITU-T G.652.D LD Bare Optical Fiber 10KM 20KM 30KM 40KM 50KM
Hicorpwell ITU-T G.652.D LD Aqua Glass Fiber Optic Bare Fiber 10KM /20M /30KM/40KM/50KM
This new fashionalbe fibre is an ITU-T G.652.D LD compliant SSMF, but with lower attenuation, chromatic
dispersion and PMD. This can provide longer transmission distance between regenerators, meanwhile
its improved bend performance exceeds the requirements of the ITU-T G.657.A1 standard.
The fibre has a 9.0µm MFD which is compatible to the majority of SSMF on the market today. The
improved bend performance of G652D LD fibre provides greater margins in the field during
installation and maintenance, and allows for the design and deployment of smaller and lighter cables
which can improve duct utilization. The improved properties consolidate the foundation of new network
and upgrades of existing networks.
