Abstract
A coarse wavelength division multiplexing (CWDM) device includes a supporting frame, a collimating lens, focusing lenses, a supporting block, and a light splitter. The supporting frame includes first frame portion with collimating lens and a second frame portion with focusing lenses arranged in an array along an extending direction of the second frame portion. The supporting block includes a first sidewall facing the first frame portion and a second sidewall facing the second frame portion. The light splitter includes a mirror on the first sidewall and a plurality of filters on the second sidewall, the filters being arranged in an array along an extending direction of the second sidewall. The filters correspond to the focusing lenses.

A coarse wavelength division multiplexing device comprising:
- a supporting frame defining a receiving groove, and comprising first frame portion and a second frame portion opposite to the first frame portion;
- a collimating lens formed on a side of the first frame portion facing away from the second frame portion;
- a plurality of focusing lenses formed on the second frame portion and arranged in an array along an extending direction of the second frame portion;
- a supporting block received in the receiving groove, and comprising a first sidewall and a second sidewall opposite to the first sidewall, the first sidewall facing the first frame portion, and the second sidewall facing the second frame portion;
- and
- a light splitter comprising a mirror and a plurality of filters, the mirror formed on the first sidewall, the plurality of filters formed on the second sidewall and arranged in an array along an extending direction of the second sidewall, the plurality of filters corresponding to the plurality of focusing lenses;
- wherein each of the plurality of filters has a predetermined inclined angle in relation to incident light which strikes the plurality of filters.
