A tunable filter includes a polarizing beam splitter and a half-wave plate that produce two equally polarized beams from an arbitrarily polarized input light. The polarized beams are directed toward a tunable component that consists of an optical substrate coated with a filter and a reflective element on its back and front surface, respectively. The pass and stop beams emerging from the tunable component are retro-reflected by roof structures and passed again through the filter. As a result of this combination of components, the filter's performance is not dependent on polarization and the filter's output channels are not shifted or deviated by tuning.

An optical wavelength multiplexer and/or demultiplexer is provided having mechanical strain relief. The mechanical strain relief is provided by mounting ears carried by a molded coupling module supporting the fiber optic cable receptacle. The mounting ears are engaged by a pair of mounting plates carried by a housing for the device. Loads applied to the fiber optic cable receptacle are transferred to the housing frame and do not adversely affect the optical pathway of the assembled device.
