Promax PROLITE-75 Mode D'emploi page 42

The GPON METER performs filtered and individualized measurements for the
three wavelengths used in fibre (1490, 1550 nm for Downstream and 1310 nm for
Upstream) and displays them simultaneously on screen. It allows you to define and
store different threshold values.
The ONT shows graphically the Upstream signal over time. This function is
especially designed for GPON technology, in which the signal is transmitted in burst
mode.
The LOSSES function allows measuring insertion losses, defining a reference
value.
By the FAULT LOCATOR module you can generate a visible laser beam, and
allows you to change it in the form of continuous laser beam or pulses. Connecting the
laser output to the cable to check, you can find cuts or breaks, identify fibres, etc.
LOGGER function stores up to 100 measurements on the memory. In each data
acquisition is stored each wavelength measure and its related data. It can be reviewed
later, transferred to a PC and printed.
The PROLITE-75 can be expanded with two more modules: an OTDR module
and an channel analyser module.
The design of the PROLITE-75 is adapted for fieldwork: is compact and resistant
to adverse conditions. Backlight LCD of 5" inches and contrast dial provides an
excellent visibility for reading. Sizes of arrow keys and selection keys are adequate and
they are prepared for ambidextrous usage. An ergonomic silicone case, perfectly
adapted, protects the instrument from hitting or accidental falling and facilitates holding
it. Slider silicone covers keep input and output connectors from dust and other external
agents and they are built into the instrument. The Li-Ion battery is rechargeable and it
has a long operation time.
In conclusion, the PROLITE-75 is the ideal tool for any installation of optic fibre,
because is ergonomically designed, robust, easy to use and economical. It has all the
functions needed to make an installation and onward maintenance.
