700-Mb/s/spl times/40-channel parallel optical interconnection module using VCSEL arrays and bare fiber connectors (ParaBIT: parallel inter-board optical interconnection technology)

Parallel optical interconnection modules are promising for high-throughput interconnections in advanced Tbit/s-class ATM switching systems. We are now working on the project called ParaBIT (parallel inter-board optical interconnection technology) to develop a module to achieve over 25-Gb/s throughput (700 Mb/s x 40-ch) and transmission over 100 m. In this paper, the design, structure, and performance of our modules are presented.
