Optical Hybrid Dry-Mate Connectors

High density solutions that meet extreme subsea pressures

Extensive product range covering many configurations to help meet the most demanding data, medium power and optical signal performance requirements. Ethernet and fiber optics perform at pressures up to 10kpsi. Offered in a variety of connector materials to help meet your corrosion, weight and design life requirements.

As organizations in the subsea industry develop more applications with fiber optic technology in mind, there has been a dramatic increase in the quantity and complexity of electro-optic connector configurations needed to fit these applications.  In order to meet the changing requirements of customers, TE has developed a comprehensive and extensive range of fiber optic products which are designed and manufactured to meet the specific and varied environmental conditions imposed on connectors today. With years of experience in underwater optical connectivity, TE can offer SEACON optical dry-mate, wet-mate, underwater mateable connectors, optical penetrators and optical fiber management systems.

  • Typical uses: Sonar & surveillance systems, Remotely Operated Vehicle (ROV)'s/ Autonomous Underwater Vehicle (AUV)'s, Blowout Preventer (BOP) monitoring equipment, neutrino detection, stress monitoring, subsea camera systems & downhole applications

Optical MINI-CON Connector

The MINI-CON connector series was the first of SEACON connector line to be adapted to fiber optic and hybrid electro/optic applications more than 25 years ago. In the intervening time, we have created many different configurations using nearly all of the MINI-CON connector sizes. We can provide multimode and singlemode products with and without electrical contacts in the mix.

Furthermore we are able to adapt to many cable designs used for interconnects and umbilical's. When considering an optical application, we encourage you to contact TE Marine, Oil & Gas (MOG) so we can help provide you with the best solution for your requirements.
