Abstract

Industry mask testing standards for SONET, Fiber channel, and others require that the measurement channel consisting of an optical to electrical converter abbreviated O/E, and preamplifier, and digitizer exhibit a nominal 4^th order Bessel Thompson response.^1,2 If the magnitude response falls within the standard limits then the measurement channel is referred to as an optical reference receiver. This results in uniform measurements across various test instrumentation setups.
