Method And Apparatus To Compensate For Polarization Mode Dispersion

View page
US Patent:
6647176, Nov 11, 2003
Filed:
Aug 15, 2002
Appl. No.:
10/219374
Inventors:
Hok Yong Pua - Plano TX
Chris Allen - Independence MO
Ken Demarest - Lawrence KS
Ron Hui - Lenexa KS
Kumar Vijay Peddanarappagari - Plano TX
Assignee:
Sprint Communications Company, L.P. - Overland Park KS
International Classification:
G02B 600
US Classification:
385 24, 385 11, 398 9, 398136, 398147, 398152, 398192, 398193
Abstract:
A polarization scrambler and a polarization mode dispersion (PMD) compensation system compensate for PMD on an active optic fiber. The polarization scrambler scrambles a state of polarization of an optical signal that carries user information. The PMD compensation system then receives the optical signal over the active optic fiber. The PMD compensation system measuring a differential group delay and principal states of polarization of the PMD in the active optic fiber. The PMD compensation system then determines a modification of the optical signal based on the differential group delay and the principal states of polarization of the PMD. The PMD compensation system modifies the optical signal in the active optic fiber to compensate for PMD based on the determination of the modification. The PMD compensation system then transmits the optical signal. By measuring the differential group delay and the principal states of polarization, the PMD compensation system adapts to changes in the PMD in the active optic fiber.

Method And Apparatus For Optical Channel Switching In An Optical Add/Drop Multiplexer

US Patent:
6922530, Jul 26, 2005
Filed:
Apr 6, 2000
Appl. No.:
09/544662
Inventors:
Hal V. Kauffeldt - Plano TX, US
Hok Y. Pua - Plano TX, US
Xiaojun Fang - Hayward CA, US
Assignee:
Fujitsu Limited - Kawasaki
International Classification:
H04J014/00
H04J014/02
H04B010/00
US Classification:
398 7, 398 83
Abstract:
An optical add/drop multiplexing unit () includes a demultiplexer () which optically isolates component signals of an optical input signal from an optical input terminal (). A plurality of switching units () can optically couple either of two outputs to either of two inputs. One input of each switching unit receives a respective component signal from the demultiplexer, and the other is coupled to a respective protection input terminal () of the multiplexing unit. One of the output terminals of each switching unit is coupled to a respective protection output terminal (), and the other is coupled to a respective input of a multiplexer (). The multiplexer has an output coupled to an optical output terminal () of the multiplexing unit, and optically combines the signals at its inputs into an optical signal for its output. The multiplexing unit is operable to cause one of the component signals from the input signal to be routed to the further terminal, or to cause a component signal present at the further terminal to be included in the optical signal at the optical output terminal.

Optical Signaling To Share Active Channel Information

US Patent:
7327954, Feb 5, 2008
Filed:
May 31, 2002
Appl. No.:
10/161274
Inventors:
Paparao Palacharla - Richardson TX, US
Hok Yong Pua - Plano TX, US
Emir Catovic - Plano TX, US
Assignee:
Fujitsu Limited - Kawasaki
International Classification:
H04B 10/08
US Classification:
398 30, 398 38, 398 31, 398 33, 398 58, 398 59, 398 60, 398 79, 398140, 398141, 398158, 398159, 398165, 398177, 398181, 398 25
Abstract:
A method for optical supervisory signaling includes determining a wavelength channel status (WCS) value, a wavelength channel failure (WCF) value, and a wavelength channel lit (WCL) value for each one of multiple data channels services by an optical communication node. The method further includes communicating the values to a second optical communication node.
