Basically, the common part of L2ROU should have an enclosure and it is equipped with RCPU to
inquire and control state of each module, R_OPTIC to make both of electronic-optical and optical-
electronic conversions, RPSU to supply power for L2ROU and a Multi-Plexer to help share
multiple TX/RX signals through one antenna. It should have Power Cable for external rectifier or
to supply required power.
In addition, L2RDU can be inserted and removed to provide service for desired band (Optional).
3.1.2 L2ROU Power Cabling
L2ROU supports both of DC-48V and AC120V of input power. As RPSU for DC-48 and RPSU for
AC120V are separated from each other, you need to select one of them in case of purchase order.
RPSU for DC -48V and RSPU for AC 120V have the same configuration and capacity while each
of the units uses different input voltage from each other.
The following figure shows configuration of RPSUs for DC -48V and AC 120V.
