Oktopus telemetry systems act as a way of transmitting live video streams, data and power up to a maximum depth of 6000 m. Consisting of a deck unit and an underwater unit (pressure housing), the system is available in different configurations (e.g. interfaces, video channels, power supply) and for the following winch cables (up to 10000 m):


  • coaxial cable
  • coax with fibre-optics
  • single core with fibre-optics


We look forward to assembling a system perfect for you and your application from our components.


Note: Of course, the system fulfills the requirements set by the DNV GL regarding personal and product safety.

VDT3 Telemetry
Oktopus VDT3 telemetry is deployed with the following winch cables:
  • Coax cable
  • Coax with fibre-optics
The respective interfaces and functions can be accessed at the deck unit (video out, FBAS PAL/SW, Ethernet 100 Mbit, RS232, RS485, RS422). Oktopus floodlights designed for use with the telemetry, as well as Oktopus cameras available as accessories, provide greater visibility, and therefore better images, in water.
The following specifications apply, depending on mode:
  Coax Cable Coax + fibre-optic cable
Max. cable lenght 10,000 m 10,000 m
Max. depth 6,000 m 6,000 m
RS232 - 2 x
RS485 / RS422 - 1 x
Ethernet (10 MBit, opt. 100 MBit) - 1 x
Switching signal max. 3 x max. 3 x
Video b/w 1 x 1 x
Video color - 2 x
24 V Connector (under water) 4 x 4 x
