Rope was a length of fibers wound together like a thicker string or cord. It was commonly used for climbing, pulling or securing items.
In 2268 Starfleet used synthetic-fiber to create ropes. Cervantes Quinn used a synthetic-fiber rope to rescue Bridget McLellan when she had fallen down a crevasse in the Jinoteur system. (VAN - Declassified novella: The Stars Look Down)
