Abstract
A splice module for optically interconnecting ends of first and second optical fibers (200, 300), each of which has a predetermined radius (Rf). The splice module comprises first and second plates (20, 30), both of which are made of silicon. The first plate 20 is provided with grooves (22). The second plate (30) is arranged on the first plate (20) to cover the grooves (22) and to define passage ways (26) for receiving and aligning the ends of the first and the second optical fibers (200, 300). The passage way (26) has an inscribed circle (28), which has a radius (Rj) larger than the predetermined radius (Rf) by a predetermined difference (D) between 0.5 μm and 1.0 μm, both inclusive.
Claims11
A splice module for optically interconnecting ends of first and second optical fibers, each of which has a predetermined radius, the splice module comprising:
- a first plate having a surface, in which at least one groove is formed, the groove extending in a predetermined direction;
- and
- a second plate having a surface, which is arranged on the surface of the first plate to define a passage way for receiving and aligning the ends of the first and the second optical fibers, wherein the passage way has in a plane perpendicular to the predetermined direction an inscribed circle, which has a radius larger than the predetermined radius by a predetermined difference of 1.0 μm or less.
