ROF has been focused on electro-optic integrated circuits and components for a decade. We manufacture high-performance integrated-optical modulators and provide innovative solutions and services for both scientific researchers and industry engineers. The modulators of the Rofea with low drive voltage and low insertion loss were primarily used in quantum key distribution, radio-over-fiber systems, laser sensing systems, and next-generation optical telecommunication. We also provide many particular modulators for customization, such as 1*4 array phase modulators, ultra-low Vpi, and ultra-high extinction ratio modulators, primarily used in universities and institutes. Additionally, we also produce RF amplifier (modulator driver) and BIAS controller、photonics detector etc. In the future, we will continue to improve the existing product series, to build a professional technical team, continue to provide users with high quality, reliable, advanced products and technical services. The 21st century is the era of vigorous development of photoelectric technology, ROF is willing to do its best to provide services for you, and create brilliant with you.
