<p>Star connector is for fibre optic cables and/or diodes. The fibres or diodes are coupled diagonally to one end face of a glass (quartz) cylinder having the squarest possible refraction profile. The opposite end face of the cylinder is mirrored, and the cylinder length is Zo=m(pi)a/2 square root 8 DELTA where m = 1, 3, 5 ........ a = cylinder radius DELTA = relative refractive index difference n2(r) = n deg. 1-2 DELTA (r/a)2 .</p> |
