Abstract
A fiber optic cable includes a core and a jacket surrounding the core. The jacket includes a base layer, a surface layer defining an exterior surface of the fiber optic cable, and an interface between the surface and base layers. The base layer is formed from a first composition that includes polyethylene. The surface layer has a thickness of at least 300 micrometers and is formed from a second composition that differs from the first composition. The second composition includes polyethylene as well as one or more additives, including paracrystalline carbon. The interface cohesively bonds the surface and base layers to one another at least in part due to molecular chain entanglement of the polyethylene of the first and second compositions.
