Fiber optic cables

Definition

Fiber optic cables are thin strands of glass or plastic that transmit data as light signals, enabling high-speed communication over long distances. These cables are crucial for various applications, including telecommunications and underwater robotics, where reliable and fast data transfer is essential. Their ability to minimize signal loss and interference makes them a preferred choice in tether management and umbilical systems.
