Product Name: High-efficiency fiber optic modem PZ1 (Fibre stretcher) 

 Product description: 
 The total optical phase modulator uses a proprietary multi-layer fiber winding technique, to achieve the optical phase modulation by the piezo-ceramic transducer (PZT), is an excellent performance, low-cost phase modulator. Another very important in the field of many sensor applications, such as ring-opening, demodulation, the interferometer system phase modulation, and so on. 
 All-optical phase modulator using multilayer optical fiber winding technology enhances the phase modulation function, to ensure that the work of the high frequency of the device. Standard products using Corning SMF-28 single-mode fiber. While providing the flexibility to customize product solutions (633nm to 1650nm wavelength products can provide), we can offer a special fiber phase modulator according to customer requirements, such as a different wavelength, polarization maintaining fiber. 
 The product can be used a lower voltage and even the common signal source for driving and without purchasing expensive drive. Fiber phase modulator the ideal accurate phase tuning of the fiber laser cavity, optical fiber interferometer system or phase modulation device
