Abstract

An optical communication mount configured for surface mounting of optical transmitters, receivers or transceivers. The mount includes a housing having holes extending from the back side to the front side of the housing. The mount includes a first set of electrically-conductive traces disposed on a bottom side of the housing for surface mounting the mount on a printed circuit board (PCB), and a second set of electrically-conductive traces disposed on the front side of the housing. The mount also includes optical fibers extending into the thru-holes from the back side of the housing. The mount includes photo devices substantially registered with the thru-holes at the front side of the housing in a manner to receive and/or transmit more optical signals by way of the optical fibers, wherein the photo devices are configured to receive bias voltages from the PCB by way of the first and second sets of electrically-conductive traces.
