Abstract

PURPOSE:To easily adjust the quantity of light by providing a turntable which functions to slide a block lens fitting base and making the turntable rotate 180 deg. by 180 deg., and branching or coupling an optical signal. CONSTITUTION:Light reflected by reflecting mirrors 2a and 2b decreases in the efficiency of coupling with an optical fiber at the position of the turntable 12 at the time of branching, so the turntable 13 is rotated by 180 deg. from the position shown in a figure. Namely, the turntable 13 is rotated to put a block 1 at the position where beams which are projected by optical fibers 7b and 7c and converted into parallel light beams by lenses 3a and 3c respectively are reflected by the reflecting mirrors 2c and 2d and multiplexed with the maximum efficiency of coupling with the optical fiber 7a; and one terminal is fixed to a block lens fitting base 12 and the other terminal is fixed to springs 14a and 15b fitted to the turntable 13 to easily multiplex the light signals even when the multiplexing/coupling efficiency in inferior.
