Sichuan Zi Guan Phoronics Technology Co., Ltd. Has a wealth of optical passive device production process and technology, has a group of experienced engineers and technicians and excellent production staff, and North America, and several well-known optical communications company and the Chinese optical communications research agencies, continue to develop new production processes and products. So that product technology has been continuously improved, as domestic large-scale production of active and passive optical components production base. With the international advanced basic science power production management and domestic reserves and rich market information, ultra-light company is a moderate pace in the field of optical communication step forward. Ultra-light company currently has a production capacity of almost all types of passive devices, and strive to make each product unique characteristics to maintain ultra-light: We MEMS technology into optical switches and attenuators, our optical switch now the world's smallest stage, the exchange is the world's fastest time respectively ms us ns three levels, and the series is the company developed, from the shackles of dependence on foreign MEMS CHIP. In efforts to enhance product development and production processes, we has even the continuous improvement and innovation to meet the challenges of the market, with excellent quality and service to meet customer needsas the company's quality policy is important.Optical passive products: MEMS optical attenuator; Mechanical manual variable optical attenuator; Mechanical Optical Switch (military grade patented products); Fiber optic delay line (patent products); Optical circulator; Mems optical switch (patented product ); Fiber collimator (special wavelength, high power spot); Extrusion polarization controller (patent products); All-plastic optical isolator; Polarization jumpers; Fiber amplifier (continuous or pulsed); DFB highly stable light source; FP hig
