1550nm 60nm Single Mode Tunable Filter

1550nm 60nm Single Mode Tunable Filter

High-speed tunable bandpass filter. As a two-port optical module, the input port receives broadband multi-wavelength light and only a small portion of the incident signal within the passband is allowed to pass through the filter and directed to the output port. The center wavelength of the selected band can be tuned to anywhere within the operating wavelength range. In our design flexibility, transmission bandwidth, wavelength tuning range can be customized. The voltage-controlled filter requires no moving parts, has fast tuning speed, and is compact and small in size. Our filters are used as suppression filters in optical systems to improve laser signal-to-noise ratio in wavelength scanning engines of optical spectrum analyzers (OSAs) and in system diagnostic communication systems.

Product features：High-speed wavelength tuning、 Wide operating wavelength range、 Flat-top/Gaussian filter shapes、 No moving parts、 Over 1 billion cycles

Part Number：--

Application area：Optical spectrum analyzer engine、 ASE noise suppression、 Optical channel diagnostics、 Test and measurement instruments、 Channel selection for wavelength lockers
