Power Distribution Unit
The Power Distribution Unit (PDU) upgrades any Surge-Gap Multimedia Tap to
allow subscriber drop powering capability. A PDU can be installed on a Surge-Gap
Multimedia Tap housing mounted either on a strand or in a pedestal.
Note: A PDU cannot be used on an existing non-multimedia tap system. See your
sales representative for further details.
Types of PDUs
The following table lists the two types of PDUs and their descriptions.
