VP Variable Optical Attenuators

1260 to 1615 nm; 50, 100 GHz Spacing; Fiber Type SM; Bare Component or With Control Board; UART; I2C Sercalo Microtechnology’s TF and TFS series of tunable optical filters are based on MEMS technology and are designed for ITU O, C and L band with 50 GHz or 100 GHz channel spacing (TFS series C band / 100 GHz channel spacing only). The series’ highly reliable tuning mechanism uses an integrated micro-mirror to select the central wavelength of the filter. TF and TFS series tunable filters are composed by an optical system where light coming from the input fiber is collimated on a fused silica grating. The grating diffracts the incoming light into its spectrum with a distinct angle for each wavelength. A MEMS mirror reflects the light onto the output collimator, which only couples the filtered spectrum into the output fiber. By modifying the mirror tilt angle, the user can choose the wavelength of the filter. Switching time is below 50 ms, insertion loss is below 3 dB and full width half maximum can be either 0.3, 0.5 or 0.6 nm. Sercalo Microtechnology’s TF series’ small standard package withstands rugged environments and the optical engine is optimized for very low size (the body without fiber sleeve only measures 14.6 x 11.2 x 9.1 mm) and well suited for direct mounting on printed circuit boards. An interface board with UART and I2C/SMBus is also available. Applications range from simple hand-held spectrometers to tunable receivers. The component is compliant to Telcordia 1221 reliability standards and ROHS requirements 2015/863/EU. Sercalo Microtechnology’s TFS series’ miniature package with a size of only 19 x 7.6 x 5.9 mm (including fiber sleeve) is ideal for applications requiring reduced size and weight. TFS series filters continuously tune from 1530 to 1570 nm with a voltage from 0 to 40 V. The component is designed to conform to Telcordia 1221 reliability standards.
