2) Remote Power Supply Unit (RPSU)
RPSU receives -48V of input. This unit is divided into DC/DC type to output +6V, +9V and +27V
of DC power and AC/DC type to receive 120V of AC input and to output +6V, +9V and +27V of
DC power.
Upon order, either of the two types should be decided. MS Connector, which uses ports to
receive inputs, is designed to accept any of AC and DC. Only in this case, the input cable is
different.
RPSU has a circuit brake to turn the power ON/OFF and has LED indicator at the top to check if
input power is normally supplied.
3) Remote Optic(R OPTIC)
Remote Optic converts optical signals into RF signals and performs vice versa. With an FSK
modem in it, the unit communicates with upper devices.
It also has internal ATT for optical compensation to compensate for optical cable loss, if any.
