Abstract
A multi-port fiber optic device (10) includes a dual fiber first collimator (12) which comprises a ferrule (18) with the input fiber (30) and the output fiber (32) therein, a gradient index rod lens (20) adhesively attached to the ferrule (18), and a filter (22) adhesively attached to the lens (20) opposite to the ferrule (18). A second collimator (14) is generally positioned in front of the first collimator (12), includes the similar components thereof while being symmetrical to the first collimator (12) along the middle portion of the whole assembly, except that one of the dual fiber of the second collimator (14) functions idle, thus the pigtail of such a fiber being removed.
