Cable Termination Unit 5941-3 (LAN)

Tinsley 5941-3 Cable Termination Unit (LAN)

Now with Remote monitoring & configuration via Wired LAN connection (5941-3 version)

The Tinsley 5941-3 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 Tinsley 5941-3 unit is designed to enable the Test Engineer tosafely and simply connect other Tinsley test instruments to the systemfor fault location and electroding.

The Tinsley 5941-3 CTU also incorporates a Cable Condition Monitor. Any changes in the Submarine Cable electrical characteristics are automaticallydetected 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.

  • Suitable for non-repeatered cables
  • Continuous cable monitoring
  • Audible warning of change in cable electrical characteristics
  • Provision for external alarm
  • Allows easy access for connection of test instruments
  • Rugged construction
  • Safety interlock
