This paper describes a complete 12 channel data link system designed for high speed parallel optical fiber communication at l. 3im wavelength. The system design is based on the technologies of 1x12 InGaAs photodiode and InGaAsP LED arrays and burst mode compatible receiver. The transmitter and receiver are linked by a 12 channel optical fiber ribbon. The system allows arbitrary data encoding protocols at any frequency between dc to 200 Mb/s/ch (total thru rate of 2. 2 Gb/s). Data transmission over I km has been achieved.
