The Advantest Q7606B Optical Chirpform Test Set is a tunable chirp test instrument operating over the wavelength range of 1510 nm to 1590 nm. It provides a controlled chirped optical stimulus used in testing optical fiber systems, transmitter chirp behavior, dispersion tolerance, and component response under variable optical frequency sweep conditions.
Key Features & Highlights
Wide tunable chirp range (1510–1590 nm)
Precise control of chirp parameters (sweep rate, linearity, frequency deviation)
Low noise and stable output
Integration with OSA (optical spectrum analyzer) or optical network analyzer for measurement
Remote control and programmability
