The byte-wide optical link in the CDF Run II silicon tracking system has endured a decade of operation and delivered an integrated luminosity of 12 fb-1. The modules consist of a transmitter converting detector signals to optical pulses, connected with 22 m fiber ribbon cables carrying signals to receiver modules out of the detector. The data transmission is conducted with edge-emitting type laser diode arrays at a wavelength of 1550 nm operating at 53 Mbytes/sec. We report on the design feature and reliability in radiation damage that exceed it original design tolerance of up to 200 kRad after 3 fb-1.
