Installation of one or several repeaters with passive splitter(s)

Considerations
– Where there are several NT units for a single RT unit, one or several splitter(s) need(s) to be used.
– For a single RT unit it is possible to mount up to four NT units.
– The passive splitter is installed in series on the RT/NT connection (coaxial cable).
– The passive splitter has no individual power supply: it feeds the power through from the NT to the RT.
– Respect the installation orientation of the repeaters and splitters, paying attention to the reference
marks on the casing.
– The length of the cable used must be noted. In order to facilitate this measurement, refer to the markings
printed on the cables: every meter, on the outer sheath. To know the length of cable installed, subtract
the number at one end from the number at the other end of the cable used.
Methodology
– The system supports a maximum of 2 repeaters and 3 splitters per route. Route means the path
between an NT unit and the RT unit.
– The variable distance between an RT and a repeater is from 0 to 70 meters.
– The fixed distance between two repeaters is 70 meters.
– The fixed distance between a repeater and an NT is 70 meters.
– The fixed distance between two repeaters encompassing a passive splitter is 50 meters.
– The fixed distance between a repeater and an NT, and encompassing a splitter, is 50 meters
– The fixed distance between two repeaters encompassing two passive splitters is 30 meters.
– The fixed distance between a repeater and an NT, encompassing two splitters, is 30 meters
– If a fixed lenght section must be coiled, respect a minimum bending radius of 200 mm.
