Abstract

This article relates generally to interfaces between systems operating in different environments and more particularly to electrical-optical interfaces between systems operating at cryogenic temperature and room temperature. Large high performance cryogenic systems will have to interface with other room temperature systems and will require high data transfer rates and a large number of I/O connections. These requirements are not consistent with maintaining low thermal losses and, hence, low levels of helium boil-offs in systems which operate near absolute zero. Neither are they consistent with low electrical noise, and eliminating the danger of introducing magnetic flux in a well-shielded environment.
