40G BPSK modulator
First Russian-made electro-optical Mash-Zender amplitude/ BPSK modulator for fiber optics
Electro - optical modulators are implemented in telecommunications and microwave photonics for data transfer and signal processing using their linear electrooptical properties. Up- to the moment our company made first Russian 26.5 GHz modulator and looks forward for more complicated designs. Dynamic range over 30 dB and great linear response made product developed by T8 good option for RF over fiber solutions.
Electro-optical modulator developed and produced in R&D facility of T8 is a part of company's program aimed on development of microwave photonics components and solutions. Our alpha samples had already demonstrated priceeffective characteristics, and we are looking forward to explore new technological horizons.
