Paper Abstract

In a previous paper, we proposed a new approach to the optical interconnection of telephone- card signals. Our approach was developed around a multimode-fiber star coupler as the optical bus, and standard optoelectronic components for transmitters and receivers. In this paper, we report on recent developments of two practical demonstrators of the above concept, namely: (1) an optical backplane for 24 X 24 I/O signals interconnection operating at 1.1 Gbit/s, with a transmitter and receiver fabricated in hybrid technology and fully connectorized to the star coupler; (2) an optical clock distribution capable of operating up to 4.5 Gbit/s with < 5% amplitude droop. Common to both units are a good S/N ratio (> 25 dB), very little time unbalance between channels (< 15 ps), and an inherent bandwidth-length product of 40 Gbit/s(DOT)m as determined by the coupler and fiber pigtails.
