Description Overview Features Specifications Overview GAOTek 1 1 Optical Line Protection Device (OLP) is a high performance optical line protection device and widely used in optical line protection of PDH, SDH, C/DWDM systems, power communication network and CATV networks. It has the capability to provide switchover to backup fiber if the main link goes down. The device is designed with separate switch control and management control which gives priority to ensure the link switching and the switching latency less than 10 Ms. It provides user friendly LED screen which displays the current alarms and the working status of the device. The device is built with industrial grade design and the system operates under harsh environments with high stability. Features It provides AC/DC dual power supply Designed with powerful graphical network management system, which supports three management modes–local Console, EMS and button setting Remote upgrade of devices can be realized The LED screen shows parameters such as current alarms, which facilitates users to clearly learn the working status of the device Lock when there is no light Support TFTP remote upgrade Provide 1 1 protection mode Support monitoring of the secondary optical fiber Support a variety of management modes: Console, EMS system and button setting Support manual and automatic switch, as well as support auto return and auto non-return modes LED screen displays parameters such as optical power, alarming information of each port, which is convenient to check the device status The switching module of the device adopts simple and stable circuit design, which is with high reliability AC/DC dual power supply and wide voltage range adaptation which is safer and more stable Mini 1U design provides compact size for easy installation Excellent thermal design and temperature adaptability allows operation under harsh environments Technical Specifications Operating Wavelength 1310 ± 50 nm & 1550 ± 50 nm Monitoring Optical Power Range 25 ~ -50 dBm Monitoring Optical Power Accuracy ± 0.5 dBm Monitoring Optical Power Resolution ± 0.01 dB Return Loss ≥ 45 dB Polarization Dependent Loss ≤ 0.1 dB Wavelength Dependent Loss ≤ 0.25 dB Insertion Loss Tx < 3.8 dB; Rx < 1.2 dB Switching Time Typical: 5 ms Maximum: 10 ms Switching Frequency > 107 Power Down State Maintain or switch to the secondary path Connector Type SC / PC or SC / APC Hardware Specification Management Mode Console, EMS and button setting Interface 1x 100 M Ethernet port 1 x RS232 3 x mode setting buttons 6 x SC/FC optical interfaces (optional) LCD Display 160 x 32 pixels Power Supply C220 V (100 V ~ 276 V) DC48 V (-36 V ~ -72 V) Dimensions 1.32 in x 8.66 in x 1.75 in (440 mm x 220 mm x 44.5 mm) (1U / 19 inch) Power Consumption < 5 W Net Weight <2.20 lbs.
