US Patent:

7406269, Jul 29, 2008

Filed:

Feb 27, 2007

Appl. No.:

11/711572

Inventors:

Donald A. Becker - Edison NJ, US
Daniel R. Mohr - Allentown NJ, US
Christoph T. Wree - Ewing NJ, US
Abhay M. Joshi - New Hope PA, US

Assignee:

Discovery Semiconductors, Inc. - Ewing NJ

International Classification:

H04B 10/00

US Classification:

398206, 398203, 398205, 398207, 398213

Abstract:

An optical coherent receiver in one embodiment has a heterodyne configuration, and in another embodiment has a homodyne configuration, in each configuration employs multiple feedback signaling and analog/digital processing to optimize response to a modulated optical input signal, the provision of both individual RF I and RF Q channel outputs.

International Classification:

H04B 10/06

US Classification:

398208, 398204

Abstract:

Repeaterless transmission of differential phase-shift keying (DPSK) at 10. 7 Gb/s over at least 304 km of standard single-mode fiber is obtained through use of a coherent optical receiver including electronic dispersion compensation. High receiver sensitivity and high tolerance to nonlinearities of DPSK, allow overcoming a total link loss of 58 dB with a 3 dB system margin, through use in the receiver of heterodyne detection to preserve phase distortions resulting from chromatic dispersion, to permit electronic dispersion compensation to be used.
