A motor-optical switch with integrated wave combining function

Abstract

The invention is suitable for the field of optical devices, and provides a motor photo-switch integrated with a wave combining function. The motor photo-switch comprises a stepping motor, a mechanical arm and a graduated plate, wherein a plurality of through holes are distributed in the outer ring of the graduated plate at equal angular intervals; a transmission collimator is fixed at the far end of the mechanical arm; a wave combiner reflecting end is fixed in each through hole in the graduated plate; the transmission collimator comprises a first optical fiber; the wave combiner reflecting end comprises a second optical fiber, a third optical fiber and a wave combining film arranged at the front end; and under the driving action of the stepping motor and the mechanical arm, the transmission collimator is correspondingly coupled with all the wave combiner reflecting ends in sequence. The motor photo-switch provided by the invention can be used for detecting more ONU (Optical Network Unit) channels, and has the advantages of compact structure, high integration degree and lower cost.

Description

technical field [0001] The invention belongs to the field of optical devices, in particular to a motor optical switch with integrated wave combining function. Background technique [0002] As a point-to-multipoint transmission technology in optical network, Passive Optical Network (PON) has the advantages of high security, shared bandwidth resources, and low overall engineering cost. It has been rising year by year and has become the mainstream technology of Fiber To The Home (FTTH), with broad development prospects and huge market potential. [0003] In a typical PON network system, the transmission signals include three, namely, downlink service optical signals with a wavelength of 1490nm and 1550nm, and uplink service optical signals with a wavelength of 1310nm. The hardware system includes passive optical network cable terminal equipment (OpticalLineTerminal, OLT) , Optical distribution node system (OpticalDivisionNote, ODN) and optical access terminal users (OpticalNet...
