A low cost, high performance optical interconnect

Optobus is a ten channel parallel bi-directional datalink based on multimode fiber ribbons. The design represents a series of tradeoffs between cost and performance to produce a low cost interconnect solution with a minimum of 1.5 Gbit/s of aggregate throughput.

Low-cost high-performance optical interconnect

Summary form only given. The optical waveguides have a uniformity of 1 dB. The resulting optical links have a jitter of no more than 150 ps not including pulse-width distortion, static skew between channels of less than 200 ps and dissipate 1.5 W. A representative multichannel eye pattern at 400 Mbit/s is shown. In this presentation we focus on the design approach and subsystem requirements that make this performance possible without sacrificing manufacturability or cost.
