Fiber assembly

An optoelectronic assembly comprising:

• a printed circuit board extending in a horizontal plane;
• an optoelectronic device mounted upon the printed circuit board in a vertical direction perpendicular to said horizontal plane;
• an optical fiber extending at least along a front-to-back direction perpendicular to said vertical direction;
• a front end portion of the optical fiber extending curvedly downwardly with a tip intimately confronting the optoelectronic device in the vertical direction;
• and
• an optical cement covering a joined region between the tip and the optoelectronic device;
• wherein
• a refractive index of the optical fiber is close to that of the optical cement.

An optoelectronic assembly comprising:

• a printed circuit board extending in a horizontal plane;
• an optoelectronic device mounted upon the printed circuit board in a vertical direction perpendicular to said horizontal plane;
• an optical fiber extending at least along a front-to-back direction perpendicular to said vertical direction;
• a housing mounted upon the printed circuit board and forming at least one through hole in the vertical direction;
• a front end portion of the optical fiber extending curvedly downwardly with a tip downwardly extending snugly through the through hole and intimately confronting the optoelectronic device in the vertical direction without a lens therebetween.
