  • Optical fiber switching device
    Patent number: 6539139
    Abstract: An optical fiber switching device includes a holding base, a threaded axle and two guide spindles installed in the holding base, a motor connected with the threaded axle to drive the threaded axle to rotate, and a positioning block meshed with the threaded axle and supported by the two guide spindles. When the motor is actuated, the positioning block is linearly moved along the threaded axle and kept in balance, thus a first collimating lens disposed on the positioning block is able to be precisely aligned with a second collimating lens which is disposed at a side of the holding base. Because the first collimating lens and the second collimating lens are precisely in alignment, any possible insertion loss of the optical fiber switching device is minimized.
