and thank you so much for your quick reply.
The help regarding Digital Optical Switch states: The Digital Optical Switch operates only for single bit not a sequence of bits. Thus, the status of the switch varies based on the first bit in the sequence applied to its control port.
What I want is using a sequence of Bits. The goal is to create a bit sequence, translate it in optical orthogonal states (for example linear polarization where 0 Deg represents binary 0 and 90 Deg represents binary 1) and sent those optical states as a representation of the bit to a receiver. (For a more holistic view: I try to simulate BB84 protocol.)
Maybe now I did elaborate my problem more precise.
