Abstract
Official abstract text for this publication.
An optical module includes a housing, an optical adapter attached to an end portion of the housing, and an optical transmitter assembly mounted in the housing. The optical transmitter assembly includes a TOSA including a plurality of light-emitting elements for outputting optical signals, and a circuit board electrically connected to the TOSA. The TOSA further includes a TOSA base having opposing side surfaces on which the plurality of light-emitting elements are oppositely arranged so as to form at least one pair. The TOSA base includes a light outputting surface having an optical component mounting portion formed thereon, and the optical component mounting portion mounts an optical multiplexer including a plurality of filters.
