Tunable Optical Filter (Bench Top)

This optical filter exhibits 100-nm tuning range around customer-selected center wavelength (1260-1650nm). Customer can also select FWHM and spectral shape. The output power is automatically adjusted to a target value by built-in optical power monitor and attenuator.

This product was originally designed for O-band LAN-WDM/CWDM transceiver testing, but can be used for any general purposes.

Product Type : Bench Top

Operating Wavelength：1260 nm ~1650 nm
