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. 

 

The following table lists the two types of PDUs and their descriptions. 

Coax power 

Couples the AC power on to the coaxial subscriber drop cable 

Twisted pair power  Requires a composite drop cable that contains a coaxial cable for the RF 

signal and a twisted pair for the AC power 

Note: Both coax and twisted pair power versions are available in 2/4-way and 8-way 
versions. 

 

The following features of the PDU are available in 2/4-way and 2/4/8-way versions. 

 

Available in twisted pair and coaxial drop powering versions 

 

Compatible with Cisco's Surge-Gap Multimedia Tap 

 

Provides uninterrupted downstream subscriber service during tap faceplate 
removal 

 

Current limiting using a positive temperature coefficient resistor (PTC) on a per-
port basis for maximum network reliability and subscriber safety * 

 

Coaxial drop conveniently and easily activated by a patented mechanical switch 

 

Advanced gasketing technology ensures reliability in aerial, pedestal, and vault 
deployments 

 

Insulation Displacement Connector (IDC) for fast and reliable wire connection 
for twisted pair powering 

* For the twisted pair version, PTCs are sold separately or are permanently installed 
(PDU part numbers 750595 or 750596).
