Fiber optic cables with extruded access features for access to a cable cavity

摘要

Cables are constructed with embedded discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of polymer material coextruded in the cable jacket.

主权项

1. A fiber optic cable comprising:
at least one optical fiber; a first strength member and a second strength member; and a cable jacket comprising:
a primary portion of an extrudable first polymeric material having two major surfaces and at least partially defining a cavity, the cavity having a cavity minor dimension generally oriented with a minor dimension of the fiber optic cable or the cavity having a diameter, wherein the at least one optical fiber is disposed within the cavity; andat least one discontinuity of an extrudable second polymer material at least partially embedded in and coextrudable with the primary portion, the discontinuity extending along a length of the cable, and the first polymeric material being different from the second polymer material, whereinthe at least one discontinuity allows the jacket to be separated at the discontinuity to provide access to the cavity.
