Abstract:
An optoelectronic module, comprising:an optoelectronic device; and a single-mode optical conductor including a first end and a second end, the first end being aligned with the optoelectronic device to receive optical signals therefrom, the single-mode optical conductor further including a core surrounded by a cladding, wherein the center of the core is radially offset from a center of the cladding by a predetermined distance; whereby the predetermined distance of the radial offset is sufficient to provide an offset launch condition when the second end of the single-mode optical conductor is coupled to a multimode optical fiber; and a first multimode optical fiber coupled to the second end of the single-mode optical conductor, wherein the first multimode optical fiber includes a core and a cladding surrounding the core, wherein the center of the cladding of the first multimode optical fiber and the center of the cladding of the single-mode optical conductor are substantially co-axial; wherein the core of the multimode optical fiber has a radius of approximately 31.25 micrometers and the center of the core is offset from the center of the cladding by approximately 17 to 23 micrometers.
