Selection of default pad option for pand and monitor modules
The make before break attenuation feature requires that a default attenuation padding value be chosen
for the module. The two options are:
M0 – 0 dB loss on the splitter or combiner leg when attenuator pad is removed
The M0 option is used in systems where the attenuator pad values will range from 0 dB to 10 dB.
M6 – 6 dB loss on the splitter or combiner leg when attenuator pad is removed
The M6 option is typically used in systems where the attenuator pad values range from 10 dB to
25 dB. In this situation, the additional 6 dB of loss that is placed in line when the pad is removed
will help to limit overdriving active devices further downstream and will help limit transmitter laser
clipping, and overdriving of RF amplifiers in the distribution plant.
