Optical bands

WebWhen an optical flat's polished surface is placed in contact with a surface to be tested, dark and light bands will be formed when viewed with monochromatic light. These bands are known as interference fringes and their shape gives a visual representation of the flatness of the surface being tested. WebThese optical bands are nothing but the transmission wavelength ranges of optical fibers. See the explanation given below; O – band Original band 1260nm – 1360nm 0. 33dB/km. E – band Extended band 1360nm – 1460nm 0.19dB/km. S – band Short wavelength 1460nm – 1530nm 0.22dB/km. C – band Conventional 1530nm – 1565nm 0.20dB/km.
