PONE-OD-DC, Continued
Minimum input
voltage versus
S-FTP cable
length
When the DC voltage at the input of the PONE is below
41 V
for Cat6 cable
and
41.7 V
for Cat5E then the
length
of Gigabit Ethernet (S-FTP) cable
(Cat5E or Cat6), between
radio unit receptacles
and
PONE receptacle
,
cannot reach more than 100 meters.
The following table shows the maximum S-FTP cable length versus the
voltage at the input of the PONE for Cat5E and Cat6 cable types:

The restriction is applied because of the following reasons:
 the PONE-OD-DC injector combines power and data passively and
 the voltage drop on the S-FTP cable will result in the voltage at the
input of the DC power module of the radio unit to be less than the min
allowable value for operation. Higher input voltage need to be applied
to ensure proper powering of the radio.
