Waveform distortion due to reflections in high-speed digital signaling is a classical issue of the signal integrity especially for the multi-drop transmission system. In general, the reflection characteristics and improvement measures of the multi-drop transmission strongly depend on the topology of the system in question, such as bus-configuration, star, ring, and so on. In this paper, we discuss a method of RCL (Reflection Compensation Line), formally reported in [6] as a reflection cancelling scheme, that can be applied to the bus-type multi-drop transmission system, whose length of main bus segments and stub lines are all isometric. Assuming practical application of our RCL technique to high-speed digital signaling, data rate of over 10 Gbps, the optimal set of transmission parameters are deduced by means of numerical optimization algorithm, and the performance of the RCL is discussed.

“…A multi-drop transmission is one of common signaling configuration for backplane system [1,2,3] or DDR-SDRAM wiring [4]. A main challenge for high-speed signal transmission in the multi-drop transmission system is degradation of the signal integrity due to reflections caused by the impedance mismatch at the branch points of the stub lines.…”

“…If extraordinary effort is taken to minimize the effects of connectors and stubs, large backplanes can operate at 1.5 Gb/s. Depending on implementation details it is possible to transport from 5 to 20 GB/s on a bus topology backplane [17].…”

Based on a variety of optimization criteria, recent research has suggested that optical interconnects are a viable alternative to electrical interconnects for board-to-board, chip-to-chip, and on-chip applications. However, the design of modern high-performance computing systems must account for a variety of performance scaling factors that are not included in these analyses. We will give an overview of the performance scaling that has driven current computer design, with a focus on architectural design and the effects of these designs on interconnect implementation. We then discuss the potential of optics at each of these interconnect levels, in the context of extant electrical technology.
