HSN Code is a hierarchical system of product Classification, you can explore the hierarchy below of HSN code 85176290, the most popular HSN codes used for Optical Amplifiers. The optical amplifiers use an erbium-doped fiber amplifier (EDFA) and incorporate pump lasers that operate at the wavelength range of 980 nanometers. The dispersion compensation modules (DCM) are used in long haul transmission systems.
