The DOIM (Dense Optical-electrical Interface Modules) is a
custom-designed optical data transmission module employed in the upgrade of
Silicon Vertex Detector of CDF experiment at Fermilab. Each DOIM module
consists a transmitter (TX) converting electrical differential input signals
to optical outputs, a middle segment of jacketed fiber ribbon cable, and a
receiver (RX) which senses the light inputs and converts them back to
electrical signals. The targeted operational facility is 53 MHz, and higher
rate is achievable. This article outlines the design goals, implementation
methods, production test results, and radiation hardness tests of these
modules.
