A Digital Optic Repeater with DPD is used
to expand the service area of the WCDMA base
station by improving the service regarding
the wave capacity when there is a weak field-effect
and shadow areas caused by topographical characteristics
or high-rise buildings.
Functional integration of internal modules
reduces the time needed to diagnose and respond
to the failure during on site repair and maintenance.

1) Digital optic transmission improves the
S/N ratio to provide transmission section
reliability between MHU and ROU.
2) It is not necessary to compensate the line
loss.
3) Effective network configuration allows
long-distance transmission and overcomes shadow
areas.
4) Multi-sector signal transmission is available
(1 branch/2 sectors).
5) Support 4FA service
6) Apply DPD algorithm
