About Us

• GLsun GLsun based in Guilin , China. We are member of Tradekey.com since September, 2008. Our business is related to Telecommunications industry and we specifically deal in optical switch,testing devices. Please find our product details below: optical switch 微机械式光开关，性能处于业界领先水平。其插入损耗极低(典型≤0.50dB，最大≤0.8 dB)，体积小：(L)29.0×(W)12.5×(H)8.0, 是用于动态配置分插复用器OADM、交叉连接器OXC、系统监测与保护的理想器件。纤小的封装使此光开关易于集成进高密度的光通信系统中。 optical testing devices 1.SUN-OPM-T power meter is a kind of high-performance and Intelligent Power meter. It mainly applied to test the optical loss for optical fiber, optical cable, and optical passive devices. It can also be used in optical fiber communication systems engineering construction and maintenance. With high precision, good quality and cost-effective, it is a good choice for scientific research, producer, and college. Adapting the low-noise PIN photodiode as detector, SCM Controller, it can measure optical power wavelengths from 850 to 1550nm; Displayed by linear, log and relative value, it shows great convenience for using. ***** SUN-FVA-T digital variable optical attenuator is designed by our company according to the optical communication development and project application. With the small volume, light weight, low power consumption, it has the competitive price and capability. This desk-top variable attenuator enables consistent operation in various testing condition, such as photoelectric device, optical passive component, optical fiber, optical cable, optical fiber communication, as well as the construction and maintenance of the fiber communication project. It has the high reliability, excellent capability, and exact measure. Remotes control PC software and superior specification makes it a good choice for various applications. 3SUN-OTR20 series is based on our many years experience in production and testing passive fiber optical communication devices and instrument. We learn from the advantages of the instruments abroad and domestic customer demand to make this high precise instrument. It is widely used in testing insertion loss and return loss of optical fiber cable, optical fiber, optical passive devices, optical communication and so on. It is a basic and ideal test equipment for production of testing, research and development, construction and maintenance of the vast number manufacturers, research agencies and operators. optical switch 微机械式光开关，性能处于业界领先水平。其插入损耗极低(典型≤0.50dB，最大≤0.8 dB)，体积小：(L)29.0×(W)12.5×(H)8.0, 是用于动态配置分插复用器OADM、交叉连接器OXC、系统监测与保护的理想器件。纤小的封装使此光开关易于集成进高密度的光通信系统中。 optical testing devices 1.SUN-OPM-T power meter is a kind of high-performance and Intelligent Power meter.
