SERIES OVERVIEW & CAPABILITIES
Understand the configuration.
Gigabit data interfaces in circular, micro-circular, low-profile and metal-shell formats, including combined power/data versions.
SubConn technical reference
The figures below describe the referenced SubConn configurations, not verified DepthLink alternatives. Final supplied specifications and mating compatibility are confirmed with your quotation. Qualified pressure-test values are shown as published and are not automatically working-depth ratings.
Technical information reviewed 19 September 2026Data rate1 Gbit/s
Data voltage250 V DC/AC rms
Combined power600 V; 4 A/contact; 16 A total
Configurations8, 9 or 13 contacts
Typical applications
- Underwater Ethernet
- Video and telemetry
- Control systems
Selection notes
Published cable reach is configuration-specific: 50 m for Micro Circular 9-contact and 75 m for specified Circular/Low Profile variants. Where no length is stated, 1 Gbit/s is not a guaranteed cable-distance claim. RJ45 termination also depends on cable construction.
