Abstract: A tire has a tread and a pair of sidewalls extending from each of two axial ends of the tread, at least a radially innermost ply being provided with an edge cover layer made of a conductive rubber composition and covering at least a radially inner face of a radially innermost ply and extending as far as an axial distance L, at least one of the sidewalls extending along with the carcass toward underneath the radially innermost ply as far as an axial distance Le, the axial distance L being greater than the axial distance Le, and the edge cover layer provided with the radially innermost ply having a portion contacting with a carcass, the axial distance L is at least equal to 10.0 mm greater than the axial distance Le.

Abstract: An optical receiver is disclosed comprising an erbium-doped fiber amplifier (EDFA) that is coupled to a photodiode and transimpedance amplifier without filtering output light signal in the EDFA. Optionally, a clock/data regenerator can be coupled to the electrical output of the transimpedance amplifier for compensating for noise distortion and timing jitter for affecting the control loop feeding back for adjusting the electrical current into a pump laser of an optical pre-amplifier. Furthermore, the optical receiver of the present invention can also be implemented in a transponder.
