Abstract
An optical fiber cable includes a hollow-core optical fiber. The cable is configured to have a low excess fiber length (EFL) of the hollow-core fiber. The cable is further configured to maintain a high minimum bending radius of the hollow-core fiber to prevent permanent damage to the hollow-core fiber during installation and operation of the cable.
