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. It is the fastest system available for WDM testing applications, enabling reduced testing times and greater production efficiency. The model 438 operates from 1000nm to 1680nm, to cover current testing requirements over the C and L optical bands, and address future testing requirements over the T and O optical bands. The 438 system measures wavelength to an accuracy as high as ±0.3pm, power to ±0.5dB, and OSNR to better than 40dB.
