Patent ID: 8821040

Claim:
An interposer, comprising: a planar substrate having top and bottom surfaces, said bottom surface defining at least one first guide bore, and one or more fiber bores extending from said bottom surface to said top surface, each fiber bore being in a certain position relative to said first guide bore and adapted to receive a fiber; at least one MT ferrule having an end face and comprising one or more fibers protruding from said end face, and at least one second guide bore defined on said end face, at least one alignment pin disposed in said first and second guide bores to position said ferrule precisely on said bottom surface such that each of said fibers is disposed in said at least one fiber bores and protrude past said top surface; and at least one optical component having a plurality of optical interfaces and being mounted on said top surface such that each of said optical interfaces is aligned with one of said fiber bores and is optically coupled with a fiber protruding from said fiber bores.
