Patent ID: 7526157

Claim:
A point-to-point link for the transmission of digital signals comprising two opto-electronic conversion apparatuses and an optical cable comprising at least one optical fiber having two terminal portions, each opto-electronic conversion apparatus comprising an opto-electronic device optically coupled to a respective terminal portion between said two terminal portions, comprising: at least one of the two opto-electronic conversion apparatuses adapted to keep the respective terminal portion of the optical fiber in a bent position with a bending radius R, where 1.5 mm≦R≦2.5 mm, and to keep the respective opto-electronic device optically coupled to said bent terminal portion in order to allow the transmission of said digital signals between said optical fiber and the opto-electronic conversion apparatus; and at least the bent terminal portion of said at least one optical fiber being such as to satisfy the relationship r/R<0.07*n/(35+n), where n is the stress corrosion susceptibility factor and r is the radius of the cladding of the optical fiber.
