±0.33ppm (typ: ±0.5pm) for wavelength calibration and metrology rate;

All-solid-state structure, non-mechanical moving parts optical design, fast test speed

Accurate wavelength measurement of 96Gbaud modulated optical signals

Rich trigger function

Support external or internal trigger

High Speed

The FWM8612 wavelength meter is in the ordinary single sampling mode, the sampling rate can be as high as 200Hz, which is 20-100 times that of the ordinary multi-wavelength based Michelson interferometer, the power accuracy is <0.5dB, and the repeatability is <0.02dB.

Internal trigger sampling mode

FWM8612 has a built-in trigger signal generator, and its fast measurement function, as shown in the figure below, triggers 1000Hz to measure the switching cycle and stability of ordinary mechanical optical switches, and can observe the transient wavelength and power information of the tunable laser.

External trigger sampling mode

FWM8612 fast wavelength meter supports 5V TTL trigger level and external trigger with sampling rate up to 1000Hz. It can simultaneously measure the scanning spectrum of tunable lasers, ModeMap scanning and channel calibration of tunable lasers, and synchronous monitoring of wavelength power of pulsed lasers.

Broadband working mode

High-speed modulation will make the original narrow linewidth laser (usually kHz~MHz) spectral broadening (96Gbaud modulation signal)。

Broadband working mode

FWM8612 has been further optimized on the basis of the original, and finally realized the accurate wavelength measurement of 400G QAM16 (96Gbaud) signal.
