SERCALO TUNABLE FILTERS with Interface board UART

TUNABLE OPTICAL FILTERS

The Tunable Optical Filter is based on MEMS technology and is designed for ITU O, C and L band with 50 GHz or 100 GHz channel spacing. The highly reliable tuning mechanism uses an integrated micro-mirror with switching time below 50 ms and insertion loss below 3 dB.

The bare Tunable Filter component (BCTF variant) measures only 43x11x9.5 mm and is ideal for applications requiring reduced size and weight. The miniature package withstands rugged environments and is well suited for direct mounting on printed circuit boards.

An interface board with UART and I²C/SMBus is also available.

The component is compliant to Telcordia 1221 reliability standards and RoHS requirements 2015/863/EU.

DESCRIPTION

Sercalo’s Tunable Filter is composed by an optical system where light coming from the input fiber is collimated on a fused silica grating. The grating diffracts the light with a distinct angle for each wavelength. Light is then reflected by a MEMS mirror onto the output collimator which only couples a small fraction of it into the output fiber. By modifying the MEMS mirror tilt angle user can chose the central wavelength of the filter.
