Fiber loss tester pol-580 Pol-580 fiber loss tester series is the newest handheld optical tester. It can offer the best performance for the daily maintenance for fiber network, and cwdm system, dwdm system and fttx network. At the same time, the perfect test functions and test ensurence are ideal for indoor or field testing. Autowavelength recognition Auto wavelength recognition is a new technology in communications Tester. It sends the special wavelength information and the coding Frequency to the acceptor (such as power meter) by the transmitter (such as sources), so the power meter can automatically recognize Sources wavelength and other information. It provides convenience During the test. And there is no need for communication between the Sources and power meter, which can help users saves test cost and time As well as decrease the potential error. Features:g ân the most perfect testing function: 1. Combine pos-530 laser source and pop-560 power meters testing function and Visual fault locator to be a real multi-tester. 2. Three kinds of modulated signal generatedg270hzb1khzb2khz, perfect for Fiber recognition and marker in field. 3. Autowavelength-recognition. Power meter can auto recognize the sourcesoptical Wavelength, and switch automatically. No need for communication between Launcher and acceptor. Saving test time and decreasing the potential error 4. 21 calibrated wavelengths offered to meet the customerstesting requirement. Such as fttx 1490nm or dwdm 1625nm. 5.
