1. A fiber optic cable comprising:
at least one hollow-core optical fiber configured to support and guide the propagation of light at a wavelength of 1310 nanometers, the hollow-core optical fiber comprising a hollow core region surrounded by a microstructured cladding region, the hollow-core optical fiber being configured to guide the propagation of light within the hollow core region by total internal reflection at an interface between the hollow core region and the microstructured cladding region such that a majority of light transmitted through the hollow-core optical fiber travels within a gas or a vacuum of the hollow core region;
an optical fiber connector coupled to each end of the at least one hollow-core optical fiber, wherein each optical fiber connector is configured to operably receive and transmit light at a wavelength of 1310 nanometers; and
a cable housing encasing the hollow-core optical fiber within, the cable housing comprising one or more materials configured for outdoor use.
