The PROLITE-77 is an instrument optimized for analysis, installation and maintenance of fibre optics networks based on GPON architecture (Gigabit-capable Passive Optical Networkit), that is, networks based on technology FTTX / PON, that provide speed over 1 Gbps. The instrument provides filtered measurements, individualized and simultaneous for the three wavelengths that are used in fibres (1490 and 1550 nm for Downstream and 1310 nm for Upstream). It provides quick access to all options of the instrument by means of a straightforward graphical interface.
The PROLITE-77 is simply and easy-to-use, directly accessing the most important functions by a single keystroke. Just plugging one end (from the distribution centre) to the OLT input and other end (from the user) to the ONT input and pressing the corresponding key you will read the results on the display. The PROLITE-77 acts as a pass-through device and is able to extract a small percentage of the transmitted signal for measurement, so the fibre optic service is not interrupted |
