Abstract:
Disclosed herein is an optical module including: an optical element mounted on a substrate; and an optical connector mounted corresponding to the optical element so as to change a path of an optical signal of the optical element and transfer the optical signal having the changed path. The optical module may provide various communication performances using an optical connector in which first and second connector parts are optically coupled stably to each other. Particularly, the optical module does not have a silicon optical bench (SiOB) as a medium, thereby making it possible to reduce a thickness of a product.
