Optical interconnect solution
View Patent ↗A low-cost, high-speed optical interconnect replacement for current electrical interconnects on printed circuit boards is provided. The invention achieves its goal by including an optical transmitter module or optical receiver module mounted in close proximity to a modulator used to encode optical signals from electrical impulses or decode optical signals to electrical impulses. A bare optical fiber is then used to transmit the signal from an optical encoding source to an optical receiver, providing a high-speed method of replacement for traditional electrical interconnects.
1. A microconnection between two printed circuit boards, said microconnection including a single bare optical fiber having two ends, wherein one end is engaged to a first microconnection on a first printed circuit board, and wherein the other end is engaged with a second microconnection on a second printed circuit board, wherein each of said microconnections includes a retention means for holding said bare fiber end including a detent, a cap made from a durable material that permits light transmission therethrough, wherein when said bare fiber end is present within said retention means and flush against said detent, said bare fiber end is simultaneously in contact with said cap, and a transmitter and/or receiver module to send and/or receive spatial transmissions from said bare optical fiber through both of said cap and said lens, and wherein said bare fiber end is in direct contact with said cap and said cap is in direct contact with said lens.
2. The micro-connection of claim 1 wherein said bare optical fiber permits information to be transferred between printed circuit boards at a transfer rate of at least 10 Gb/s.
