a router that can connect to many clients using only one optical fiber between the workstation and the router. allowing an ethernet like configuration that can operate entangled photon communication but also classical optical communication.
Yes, being purely passive it can route without limit bulks of optical channels together to its connected transceivers, potentially providing simultaneous TB/s links from workstations to all its other connected worstations.
Yes the router can also connect servers between themselves, or workstations or any transceiver devised for enatangled photon communication.
the transceivers can be anything from 1m to 120km from the router.
Yes it can ; provided the QKD stations are designed to work using many different wave lengths.
Yes , provided its connected transceivers use the entangled photon communication technology, or distributes encryption keys with a safe QKD protocol.
