Micro composite fiber optic/electrical cables

摘要

Composite cables operative to transmit information in optical transmission and/or electrical power modes. The composite cables include an optical fiber operative to transmit light comprising a silica-based core with a silica-based cladding having a lower index of refraction than the core, the core and cladding are surrounded by two layers of plastic that define a soft primary coating surrounding and in contact with the cladding, and a relatively rigid secondary coating that surrounds and is in contact with the primary coating. The optical fiber has an outside diameter of about 250 mum to about 500 mum or more, and an electrical conductor surrounds the secondary coating. The composite cable includes an outermost cable jacket layer having an outside diameter of about 3,500 mum or less.
