5941 Cable Termination Unit for non-repeatered submarine cables.
The Tinsley 5941 CTU is the ideal termination unit for non-repeatered submarine cables. 
It offers a simple method of selecting an open or short circuit condition and a safe means of discharging the cable. The unit is designed to enable the Test Engineer to safely and simply connect other Tinsley test instruments to the system for fault location and electroding.

The Tinsley 5941 CTU also incorporates a Cable Condition Monitor. Any changes in the Submarine Cable electrical characteristics are automatically detected and an alarm is triggered. 
An output from the alarm is also available for connection to outside devices.

The unit can be connected to the cable via a 
dedicated cable connected to the fibre optic 
cable metallic conductor. 

Alternatively, the fibre optic cable can be routed 
into the CTU with a direct path through the unit 
for the optical fibres. 
Options that can be set at the time of installation 
enable the unit to be used with a wide 
range of cable lengths and types.
