Abstract
An optical transmitting module includes: light sources configured to output optical signals, an optical multiplexer configured to multiplex the optical signals output from the light sources, a collimating lens configured to convert an optical signal output from the optical multiplexer to a form of parallel beam, a package inside which the light sources, the optical multiplexer, and the collimating lens are provided, and an optical isolator disposed on one inner surface of the package, in which the optical signals output from the light sources are multiplexed into a single optical signal through the optical multiplexer disposed inside the package, and the single optical signal passes through the collimating lens and is then optically coupled to an optical fiber stub in a receptacle through a focusing lens disposed outside the package to be output externally.
