A 12-channel multimode fiber-optic 1.0625-Gb/s fiber channel receiver based on COTS devices and MCM-L/COB/BGA packaging

We describe a high-performance, 12-channel multimode fiber-optic receiver array using a combined multichip module laminate (MCM-L), chip-on-board (COB), and ball grid array (BGA) packaging technology. The array operates at a minimum speed of 1.0625 Gb/s per channel with good channel-to-channel uniformity. Each channel has sensitivity better than /spl sim/18 dSm and dynamic range better than 12 dB. Other important characteristics are good uniformity in rise time, fall time, and peak-to-peak output voltage amplitude across all the channels. The results demonstrate this OE receiver array packaging approach is applicable for a wide variety of platforms that have very stringent requirements in high packaging density, high performance, and low cost.
