Abstract
An optical module device including optical devices 110, a substrate 100 on which the optical devices 110 are disposed, optical fibers 200 that implement optical communications with the optical devices 110, an optical bench 300 to which the optical fibers 200 are fixed and which implements optical coupling between the optical devices 110 and the optical fibers 200, a cover block 400 that covers the optical bench 300 and a copper cable receptacle 500.
Claims18
An optical module device, comprising:
- one or more optical devices;
- one or more optical fibers that communicate with a corresponding one of the one or more optical devices;
- a substrate on which the one or more optical devices and an integrated circuit (IC) device for driving the one or more optical devices are mounted at a set position on the substrate;
- an optical bench comprising a bench body, a seating groove that holds the one or more optical fibers in a lengthwise direction, and an optical unit that is formed at an end of the seating groove, the optical unit having an end that faces the one or more optical fibers to concentrate light transmitted between the one or more optical devices and the one or more optical fibers and to change the direction of the concentrated light;
- and
- a cover comprising a cover body, a lens assembly that includes one or more lenses corresponding to the one or more optical fibers and that concentrates light transmitted between the optical unit and the optical fibers, a retainer that includes a bottom surface that protrudes from the cover body at a position corresponding to the seating groove to hold the one or more optical fibers, and an injection port formed through the cover body, wherein the cover is configured to be coupled to the optical bench,
- wherein the cover further comprises a step jaw that protrudes from the bottom surface of the cover body between the lens assembly and the injection port, and the step jaw limits a position of the one or more optical fibers.
