Overview

GAOTek optical transmitter with external modulator has the tunable range of wavelength 1528.77 nm to1563.86 nm, the adjustable wavelength >35 nm with the traditional ITU standard wavelength ±0.8 nm (±100 GHz) can tunable, is a completely new concept and application ranges. It includes all C band’s usable wavelength, its database stores 89 ITU standard wavelength channels (C band 0.4 nm gallery interval). users can achieve the selection, switch and route etc wavelength management function quickly, accurately. high wavelength accuracy, high wavelength stability, fast tuning rate, perfectly adapt the NGB DWDM system. Its high wavelength flexibility and replaceability will become the development direction of the next generation broadcast television network NGB external modulation optical transmitter.
