Frequently Asked Questions (FAQ)
Q: How does the lightweight jacket improve AUV/UUV performance?
A: Reduces tether mass and hydrodynamic drag, extending mission range and lowering energy consumption.
Q: Can buoyancy be precisely tuned?
A: Yes. Factory calibration achieves exact neutral buoyancy for salinity, temperature, and depth.
Q: Is the cable suitable for fully untethered AUVs?
A: While designed for tethered/hybrid modes, its low weight and compact design suit docking umbilicals and recoverable tethers.
Q: Are fiber optic telemetry options available?
A: Yes. Single-mode or multi-mode fibers support high-bandwidth sonar, video, and sensor data.
Q: How is long-term reliability ensured?
A: Through accelerated life testing (flex, pressure, temperature cycling) and proven materials used in multi-year deployments.
