Patent ID: 8843000

Claim:
An optical fiber transmission system, comprising: a light emitting source; a plurality of light receiving terminals, a plurality of optical fibers connecting the light emitting source to the light receiving terminals; and a plurality of controlling modules positioned between the light receiving terminals and the optical fibers; wherein each of the plurality of controlling modules comprises a controller, a signal analyzer, and a reflective member, the signal analyzer and the reflective member are respectively connected to the controller; wherein the light emitting source generates an optical signal including an aim address message, the signal analyzer stores a pre-setting receiving address, and compares the aim address message with the pre-setting receiving address, if the aim address message corresponds to the pre-set receiving address, the optical signal is transmitted through the controlling modules and allowed to enter the light receiving terminal; and if the aim address message does not correspond to the pre-set receiving address, the signal analyzer sends a starting signal to the controller, and then the controller controls the reflective member to reflect the optical signal back to the optical fiber according to the starting signal.
