- 2 single-mode fibres
Conductor: stranded oxygen-free copper, to VDE 0295 Class 6
Insulation: PE / FEP
Armouring: steel tape armour
Shield: tinned copper braid, coverage ≤85%
Wrapping: non-woven tape
Inner jacket: PUR (black)

How is a watertight fibre-optic hybrid cable made? The cable combines power transmission with high-performance signal transmission in one construction and provides high information throughput and high-speed data capability. Kevlar is used as the tensile strength member, with breaking force up to 1T, so the cable is not damaged by excessive pull during retraction. A dispensing machine continuously fills water-blocking gel to meet horizontal and vertical watertightness and buoyancy requirements. The cable resists tension, kinking, oil and ageing, and can be reused, meeting the requirements of current-generation underwater equipment.
