Abstract

Wavelength accuracy is an important requirement for wavelength division multiplexed (WDM) optical fiber communication systems. It appears likely that WDM will expand from the current 1530–1565 nm WDM C-band into other wavelength regions, and may ultimately cover the entire range from about 1280 to 1630 nm. Wavelength calibration references are needed for instruments such as optical spectrum analyzers (OSAs), tunable lasers, and wavelength meters that are used to characterize WDM system components and measure the channel wavelengths.
