<P>PROBLEM TO BE SOLVED: To provide an optical transmitting system for stably transmitting data regardless of a relative position of an optical fiber and a light receiving element even when the optical fiber has a fluctuating curved state and a short optical path length. <P>SOLUTION: The optical transmitting system comprises a means for enlarging a distribution angle of light from a light emitting element. The optical transmitting system comprises the light emitting element, and an angle enlarging means enlarging a distribution angle of light incident on an incident end from the light emitting element and emitting the angle-enlarged light from the emission end. The distribution angle is an angle made from a straight line connecting a point of optical intensity of a half of the maximum optical intensity and the light source or the optical element, and the optical axis, in a normal face to the optical axis and a far field pattern (hereafter, referred to as FFP) of light emitted from an optical element. The angle enlarging means emits by enlarging the distribution angle of light from the light emitting element incident on the incident end. <P>COPYRIGHT: (C)2007,JPO&INPIT |
