ABSTRACT:
An optical reflective star device having a number of ports for distributing each signal fed to a port over the other ports. Said optical reflective star device is made up a number of star elements and comprises a number of reflectors provided at reflection points in the reflective star device. At least one of the reflectors is an orthogonal polarisation reflector.
