What is an Optical Spectrum Analyzers?
An optical spectrum analyzer (OSA) quantifies and displays the power of an optical light source over a given wavelength range. Much like an RF spectrum analyzer, the OSA displays the power in the y (vertical) axis and the wavelength in the x (horizontal) axis. Three key parameters that are measured by an optical spectrum analyzer are the wavelength, power level, and optical signal-to-noise ratio (OSNR).
A fiber optic communication network utilizing wavelength division multiplexing (WDM) to allow multiple optical carrier signals to be carried over a single fiber is an ideal application for the OSA spectrum analyzer. Long haul networks with inline amplification rely on accurate optical power and OSNR measurements to ensure optimal performance.
While some optical spectrum analyzers are tailored to specific wavelength bands (C, L, O-band, etc.), others can operate effectively across multiple bands. Spectrum analyzer optical testing also enables transmissivity and reflectivity testing of optical components at specific wavelengths, and amplifier noise testing.
