The third generation G3 connector utilizes existing HydraLight technology and is available in 6 channels with either singlemode or multimode optical fiber. The G3 connector offers low profile optical connectivity combined with simplicity of operation and is ideally suited for tight interfaces requiring low loss optical performance. This connector can incorporate flat or angle polished contacts making it ideal for either signal communication systems or optical measurement and sensing systems such as tubing hanger connections, tree connections, riser monitoring systems and life of field seismic systems (LoFS).

  • 3rd generation connector utilizing HydraLight technology
  • Suitable for stab, configurable for diver and ROV operations
  • 6-channel optic (singlemode, multimode)
  • Up to 15,000 psig (approx. 35,600ft/10,550m)
  • Internal pressure compensated
  • Operating temperature 107°C -150°C 
  • Very small form factor with low loss optical performance
  • Few internal moving parts
  • Simplicity of operation
  • Stainless steel, titanium
  • Typical uses: Downhole sensing and communication, downhole completion tools, compaction monitoring, reservoir monitoring, seismic profiling and fiber sensing, space-restricted applications, Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) systems
