MULTI-CHANNEL OPTICAL ASSEMBLY AND TEST SYSTEM

摘要

A multi-channel optical assembly and a test system comprising same. The multi-channel optical assembly comprises an optical channel array (200, 500, 600, 700), a first optical converging element (206, 508, 608, 708), a filter device (208, 610, 710, 810) and an optical path converter. The optical channel array (200, 500, 600, 700) comprises N first optical channel media, N second optical channel media, and a third optical channel medium, N being an integer greater than 1. On a first end surface of the optical channel array (200, 500, 600, 700), terminals of the N first optical channel media and terminals of the N second optical channel media are distributed symmetrically, and a terminal of the third optical channel medium is located at the center of symmetry. The first optical converging element (206, 508, 608, 708) is coupled to the first end surface, and is configured to converge a first optical signal from at least one first optical channel medium to a first position. The filter device (208, 610, 710, 810) is located at the first position, has a partially reflecting and partially transmissive material, and is configured to reflect the first optical signal converged at the first position back to the first optical converging element (206, 508, 608, 708) so that the first optical converging element (206, 508, 608, 708) inputs the reflected first optical signal to a corresponding second optical channel medium, transmit a second optical signal from the third optical channel medium to the optical path converter, and transmit and output a third optical signal returned by the optical path converter to the first optical converging element (206, 508, 608, 708) so that the first optical converging element (206, 508, 608, 708) inputs the transmitted third optical signal to a corresponding first optical channel medium or second optical channel medium. The multi-channel optical assembly reduces the space occupied by each element in an optical network system, thereby facilitating the integration, maintenance and management of the optical network system.
