Patent ID: 7665905

Claim:
An optical module adopted to be connected to an optical fiber, comprising: a ferrule having a fiber holding hole, a first end and a second end configured for mechanical coupling to an optical connector having the optical fiber; a flexible printed circuit board fixed to the first end of the ferrule; an optoelectric device connected to an electric circuit of the flexible printed circuit board such that the optoelectric device is aligned with the fiber holding hole; a built-in fiber secured in the fiber holding hole with a first end of the built-in fiber facing the optoelectric device, and a second end of the built-in fiber being flush with an end surface of the second end of the ferrule such that the second end of the built-in fiber is configured for optical coupling to the optical fiber; and a housing at least partially enclosing the ferrule, the housing having an optical connector installation opening with the second end of the built-in fiber being exposed within the optical connector installation opening.
