G.652d
A single mode optic fiber with low water peak and compatible for long distance communications.
Low water peak optical fiber “G652d” is a single-mode fiber produced by vapor axial deposition method (VAD). The fiber with a quartz core alloyed with Germanium and quartz cladding complies with the recommendations ITU-T G.652d.
The fiber’s dual acrylate coating ensures its high strength, structural integrity and long service life. The fiber works in a full spectral range of different access networks including FTTH and can be applied in long distance communications.
The G652d fiber shows reliable results of weldability with most available on the market SMF fibers. Fiber quality’s compliance with international standards is confirmed.

G.657.A1
A single mode optic fiber with a low water peak and with a reduced sensitivity to bends.
NBG ONE LIGHT is a single-mode optical fiber with a low water peak (G657A1/G652D) hybrid with advanced characteristics is a fiber with a reduced sensitivity to bends.
The fiber is produced by vapor axial deposition method (VAD) with a quartz core alloyed with Germanium. It completely complies with the requirements of ITU-T G.652d and exceeds ITU-T G.657A1 parameters of macrobend loss and attenuation. Double acrylic coating provides it´s high strength and long service life. The fiber works in a full spectral range of different access networks, including FTTH, and can be applied in long-distance communications.
Fiber-bending resistance and improved attenuation parameters give an advantage in the application for residential networks. The quality control system of the factory confirms plug compatibility with fiber (G652d) as well as with all on the market available SMF fibers.
