Abstract
The present inventive concept herein relates to multi-channel optical modules, and more particularly, to a multi-channel optical module capable of processing a plurality of signals having different optical wavelengths. The multi-channel optical module may include a stem including one or more cavities; at least one lead pin formed in one or more cavities; a plurality of optical devices formed in the one or more cavities; and a filter portion forming an optical path between the plurality of optical devices and an optical fiber by separating a plurality of optical signals according to a wavelength. According to the inventive concept, processing capacity of the optical module may be improved. Also, according to the inventive concept, electrical and optical cross talk of the optical module may be reduced.
