Zusammenfassung:A V-groove dual fiber DWDM collimator (1) including an optical lens (10) and a V-groove dual fiber ferrule means (12) fixed with each other. The ferrule means (12) includes a V-groove chip (14) and a cover chip (20) commonly enclosed by a protective guiding sleeve (22) wherein two pigtail fibers (24, 26) are respectively received within the corresponding grooves (16) of the V-groove chip (14). The V-groove ferrule means (12) is itself fixed by adhering its own internal components (14, 20, 22) and the embedded fibers (24, 26), and also fixed to the lens (10).
