Product Details

ROF-PM series of low-speed electro-optical phase modulator

Product description

Lithium niobate electro-optical phase modulator has the characteristics of low insertion loss, high modulation bandwidth, low half-wave voltage and high damage optical power. It is mainly used in optical chirp control of high-speed optical communication system, phase shift in coherent communication system, the generation of sidebands in ROF system, and the reduction of stimulated Radiation Scattering (SBS) in analogue optical fiber communication systems.
