Bristol Instruments

The 438 Series Multi-Wavelength Meter from Bristol Instruments (booth 3412) combines Michelson interferometer-based technology with fast Fourier transform analysis in order to measure the wavelength, power, and optical signal-to-noise ratio (OSNR) of as many as 1000 discrete optical signals. With features such as high accuracy and a measurement rate of 10Hz, the model 438 provides the most precise, reliable, and efficient wavelength testing to satisfy the needs of any manufacturing engineer, the company claims.
