Abstract
An assembly of two fiber optic ferrules allows for the mating of a CWDM fiber optic ferrule with a non-CWDM fiber optic ferrule. The CWDM fiber optic ferrule has optical fibers that carry optical beams with at least two different wavelengths, which the non-CWDM ferrule has optical fibers that carry only one wavelength. The CWDM fiber optic ferrule and the non-CWDM fiber optic ferrule have optical fibers that are inserted along parallel axes. The non-CWDM fiber optic ferrule has a lens pitch that matches the CWDM ferrule.

An optical assembly comprising:
- a first CWDM fiber optic ferrule having at least one optical fiber with at least two optical beams at different wavelengths, the at least one optical fiber held inside the first CWDM fiber optic ferrule by at least one optical fiber supporting structure, 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 configured to mate with the first CWDM fiber optic ferrule, wherein the second non-CWDM fiber optic ferrule has a first optical fiber to carry a first optical beam 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 first optical fiber supporting structure for the first optical fiber and a second optical fiber supporting structure for the second optical fiber.
