Cisco Power Distribution Unit
A key requirement for today’s Hybrid Fiber Coax distribution networks is reliability. The
New Cisco Power Distribution Unit (PDU) not only provides improved RF specifications
New Cisco Power Distribution Unit (PDU) not only provides improved RF specifications
and packaging, but also has increased survivability against power surges as compared to
its predecessor.
The PDU upgrades any Cisco Surge-Gap and standard Multimedia tap to provide power
distribution capability. Operators only need to install PDUs at tap locations where
revenue-generating telephony subscribers are located. This cost-efficient approach
matches incremental expenses with new revenue opportunities.

The PDU is available in 2/4 way and 8-way sizes, and is designed to provide safe power
distribution to individual subscriber drops. Both versions of the PDU, the coaxial drop powering and
the twisted-pair powering, are compatible with all Cisco
Surge-Gap and standard Multimedia
taps
. After initial installation, the PDU allows power activation and current limiting on a per-port
basis without interruption to any subscribers. These features provide for minimum subscriber
interruption plus ensure that individual subscribers and the overall network are isolated from
potential ground faults and other AC powering concerns.
