Title:
EXTENSIBLE OPTICAL SUGNAL TRANSMISSION CABLE
Document Type and Number:
WIPO Patent Application WO/2010/074259
Kind Code:
A1
Abstract:
Disclosed is an extensible optical signal transmission cable having an extensity of 10% or more and an optical transmission loss of less than 20dB/m when the cable is loosened. The cable comprises an elastic cylinder having an extensity of 10% or more and at least one optical fiber wound around the elastic cylinder. The optical fiber has a bending diameter (R) which is not smaller than the bending limit diameter (Re). The extensible optical signal transmission cable is compliant with the shape deformation, can transmit an optical signal when the cable is extended or contracted, and can be used for repetitive extension and contraction.
