The universal optical mechanical splice is developed for mechanically connecting fibers of 250μm to 900μm diameter, filled with special gel having the same refractive index as glass. The mechanical splice connects two fibers quickly and stably with a simple press of the cover—no separate installation tools needed—providing a low-cost and fast alternative to fusion splicing. The splice uses V-groove technology to maintain physical contact between fibers, supporting 900/900μm, 250/250μm and 250/900μm fibers.
