Abstract:
1. An optical module, comprising: a housing; an optical adapter attached to an end portion of the housing; and an optical transmitter assembly mounted in the housing, wherein the optical transmitter assembly comprises a TOSA comprising a plurality of light-emitting elements for outputting optical signals, and a circuit board electrically connected to the TOSA, wherein the TOSA further comprises a TOSA base having opposing side surfaces on which the plurality of light-emitting elements are arranged in opposition with at least one light-emitting element on one side surface and the other of said light emitting elements on the opposing side surface so as to form at least one pair and so that optical paths of emitted light are parallel to each other, and a plurality of mirrors to reflect each optical signal emitted from the plurality of light-emitting elements, wherein at the mirrors each optical signal is reflected toward an optical multiplexer, wherein the TOSA base comprises a light outputting surface having an optical component mounting portion formed thereon, and the optical component mounting portion mounts the optical multiplexer including a plurality of filters and mirrors arranged linearly, and wherein a plurality of optical signals form wavelength multiplexed light by reflection at the mirrors or transmission through the filters.
