This paper describes the design and performance of a 64-channel equalization and blocking filter. It utilizes a free space lens and grating multiplexer with micromechanical tilt mirrors providing variable attenuation. The module achieves a 5-dB insertion loss with a 3-dB passband of 87 GHz for 100-GHz spaced channels. The attenuation range achieved is in excess of 35 dB, making it suitable for wavelength blocking in switching applications. The device has been demonstrated to be compatible with 10- and 40-Gb/s transmission.
