1. An assembly of two fiber optic ferrules comprising:
a first CWDM fiber optic ferrule having at least one optical fiber with at least two optical beams with different wavelengths therein, wherein the at least two optical beams are wavelength division multiplexed inside the same at least one optical fiber; and
a second non-CWDM fiber optic ferrule having a first optical fiber to carry one of the optical beams demultiplexed at a first wavelength and a second optical fiber to carry the second optical beam demultiplexed at a second wavelength different from the first wavelength, wherein the second non-CWDM fiber optic ferrule has a front face to engage at least a portion of the first fiber optic ferrule and a plurality of external lenses, the plurality of external lenses being disposed behind the front face.
