ABSTRACT:
A system and method for providing a wavelength division multiplexer is disclosed. In one aspect, the system and method include providing a housing for the wavelength division multiplexer. The housing includes a first port having a first aperture therein, a second port having a second aperture and a first plurality of apertures therein, and a third port having a third aperture and a second plurality of apertures therein. The second and third apertures are coupled to the first aperture. The first plurality of apertures are disposed symmetrically around the second aperture. The second plurality of apertures are disposed symmetrically around the third aperture. In another aspect, the method and system include providing a wavelength division multiplexer. The wavelength division multiplexer includes a first port including a first collimator, a second port coupled to the first port, and a third port coupled to the first port. The second port includes a second collimator and a first plurality of joints for affixing the second collimator. The first plurality of joints is disposed symmetrically around the second collimator. The third port includes a third collimator and a second plurality of joints for affixing the third collimator. The second plurality of joints is disposed symmetrically around the third collimator.
