OTDR Wavelength 1310nm/1550nm ,850nm/1300nm Wavelength1310nm/1550nm, 1310nm/1550nm/1490nm 13/15dB 22/23dB 32/30dB 36/35dB Overview RUIYAN OTDR-4000 series portable optical time domain reflectometry (OTDR) is the latest FTTx optical fiber cable-based test instrument. It has light weight, elegant appearance, small size, easiness of installation and maintenance, high-capacity built-in battery. It provides multiple built-in test wavelengths and optical testing functions like visual fault locator (VFL). As a new product specially designed for FFTx network testing, it provides site technicians with the highest performance and upgrade services. Featuresl        Advanced anti-reflective LCD, display interface is clearly visible in bright lightl        (VFL)Visual fault location functionl        It provides high-speed USB port, waveform file conversion and printing conveniencel        Long-lasting lithium battery, ideal for long-time outdoor construction workl        Online upgrade function, users do not have to go back to original factory to upgrade the system. Main functions1. Fast automatic testAutomatic test function allows the user not to have to know more details about the equipment operation, test steps become very simple. User only needs to connect in the optical fiber, click [Test] button, then the instrument will automatically set optimal test conditions and eventually give accurate test results, such as the test curve and event lists. 2. Fast curve analysisIt can find out the event point or failure point in test curve and its location information quickly and accurately test curve, and list all event information in the circuit in the form of event list. This is very helpful for circuit maintenance personnel, not only improves the testing efficiency, but also eliminates the need to learn difficult background knowledge. 3. Powerful document managementIn addition to the ability to store, view, delete the files in the machine, it also provides PCL language-based laser or jet printers to print test reports. Besides, it also utilizes PC software to realize high-speed communications with PC via USB cable. 4. Convenient VFL functionWith visual IR VFL function, it can easily and quickly the locations of disconnecting points or big loss points in short-distance optical fibre links, so that the maintenance personnel could take measures in shortest time therefore saving a lot of time. 5. Manual test modeUsers can choose real-time test mode or average test mode according to the testing needs. Real-time test can fast test the dynamic change of optical-fibre links. It is mainly used for the connecting occasions requiring monitoring or observing optical-fibre links at real time. 6. Average test mode Average test mode is used to withhold the noise in test curves to the most extent, therefore obtain more accurate testing results. In average test mode, the number of averaging tines will influence the effects of suppressing the noise in test curves. The bigger the number of time is, the effect the time is, but the testing time is to be extended accordingly. Therefore, user should set averaging time based on actual need.  7. Dead zone test modeIt is suitable for the test of ultra short-distance optical fibre. Specifications
