4.3.2 FT5E Wiring
Before wiring, determine the FT5E RF input power based on the number of channels (broadcast or bro
narrowcast). Set the parameters for the 'AGC model,' 'BC MGC,' or 'NC MGC' in the AIMA3000 configuration system
according to the actual input RF power, and set the parameters for the alarms.
See Chapter 5.1.2 for more information about parameters in the FT5E module port configuration interface.
a. Connect narrowcast and broadcast RF input cables to the narrowcast and broadcast input ports on the back panel of
the FT5E, respectively.
b. Check whether the 'RF11' indicator light on the module’s front panel is green. If it is green, proceed to the next step. If the
'RF1' indicator light is orange or red, connect a spectrum analyzer to the broadcast and narrowcast input test points to
measure broadcast and narrowcast input power. According to the obtained values, make adjustments to the broadcast
and narrowcast input signals or the 'BC MGC' and 'NC MGC' parameter settings for the corresponding ports until the 'RF'
indicator light turns green.
c. Check whether the 'LSR' indicator light is green. If it is green, proceed to the next step.
If the indicator light is orange, check the FT5E port alarm interface in the AIMA3000 configuration system and ensure
that the laser temperature, bias current, and output power are within the normal range. If values are not within the
normal range, make adjustments according to the parameters of the alarm information until the values reach a normal
range. If the indicator light is red, check whether 'Laser Output' in the AIMA3000 configuration system FT5E port alarm
interface is switched on. If the 'Laser Output' is switched off, set 'Laser Output Control' in the FT5E port alarm interface
to 'On.' If the LSR indicator light is still red, check whether the laser temperature, bias current, and output power are
within the normal range. If values are not within the range, make adjustments according to the parameters of the alarm
information until the values reach the normal range.
d. Thread the fibre optic cables from the module’s back panel to the front panel using the fibre guide. Arrange the cables
in the fibre optic channel guide and fix them in the channel guide’s grooves.3
e. Clean the fibre optic contact and optical output port (located on the front panel of the module).
1. RF2 and LSR indicator lights function the same way as RF1 and LSR1.
2. The FT5E module’s 'NC RF Total Input Power' alarm is set to 'off' by default. Before checking the RF indicator lights, log in to the AIMA3000 configuration system and turn on the main and secondary
alarms (select HiHi/Hi/Lo/LoLo threshold values).
3. See AIMA3000 Manual for information about using the fibre guide and wiring fibre optic cables.
