<p>An optical fiber cleaver (20) with a traversing mechanism (30) and measuring device (42) to impart relative movement between the cleaving blade (28) and fiber holder (26) and precisely control positioning of the blade along the axis of the fiber (F). In one embodiment, a cleaver blade (28) is mounted on a translation stage (38) which is movable relative to a stationary platform which supports the fiber holder. The cleaver blade mechanism is movable along the stage so as to precisely locate the blade for a cleaving operation. The cleaver is useful for producing stacks of different optical fibers fusion spliced together and ensuring that each fiber in the stack is precisely the correct length to maximise its characteristics. The measuring device or position indicator (42) is coupled to the traversing mechanism (30) and can be calibrated to a start position at the end of a first optical fiber. After a second optical fiber is fusion spliced to the first optical fiber, the cleaver can measure a precise length of the second fiber as predetermined for its characteristics. Subsequently additional optical fibers can be spliced to the end of the stack and cleaved to a precise length. The cleaver of the present invention enables for repeatability in producing tacked fibers and lends itself to automated production.</p> |
