First Claim
Patent Images
1. A card for transmitting data over at least one optical fiber, the card comprising:
- a transmitter having at least one light source and a phase modulator for phase modulating light from the source so as to create phase-modulated optical signals in the light as a function of an input electronic data stream; and
a receiver having an interferometer for reading received optical signals.

11. A method for converting an existing amplitude-based optical device to a phase-modulated based optical device comprising the steps of:
-
removing a card having an amplitude-modulated light source from an existing optical telecommunications device; and
inserting a new card having a phase-modulated light source and an interferometer into the existing telecommunications device. - View Dependent Claims (13, 14)

12. A method for manufacturing a card for transmitting data over at least one data transmitting optical fiber, the card having a transmitter and a receiver, the method comprising the steps of:
-
placing at least one light source on a backplane, placing a phase modulator onto the backplane next to the at least one light source, the phase modulator being connected to the at least one light source, but not by the at least one data transmitting optical fiber; and
placing an interferometer on the backplane.
