US Patent:

60881526, Jul 11, 2000
Filed:

Mar 8, 1999
Appl. No.:

9/265943
Inventors:

Matthias Berger - Tinton Falls NJ
Dirk Bode - Tinton Falls NJ
Daniel A. Fishman - Lakewood NJ
Gabriela Livescu - Marlboro NJ
Christian Raabe - Tinton Falls NJ
Fatimah Shehadeh - Ocean NJ
Jianhui Zhou - Freehold NJ
Martin Zirngibl - Middletown NJ
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H01S 310
H01S 3108
H01S 330
US Classification:

359334
Abstract:

An optical amplifier is adapted to cancel the Raman gain of an optical transmission path that degrades those optical signals occupying the low end of the bandwidth such that the power is transferred from the latter signals to the optical signals occupying the high end of the bandwidth. More specifically, the optical amplifier adjusts the gain that it applies to the optical signals so that it favors the signal components at the low end of the bandwidth.

US Patent:

63172313, Nov 13, 2001
Filed:

Sep 4, 1998
Appl. No.:

9/148355
Inventors:

Daniel Yousef Al-Salameh - Marlboro NJ
Gabriela Livescu - Marlboro NJ
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04B 1008
US Classification:

359110
Abstract:

Optical-to-electrical and electrical-to-optical signal conversion is substantially eliminated for performance of monitoring and maintenance functions within a wavelength-division-multiplexed optical network having a Network Control Element by detecting optical intensities of signals conveyed over wavelength channels at the optical layer. Values associated with the detected optical intensities are generated and conveyed to the Network Control Element. The Network Control element analyzes these values for the purposes of fault detection, channel power monitoring, channel signal to noise ratio determinations, channel continuity checks, and network provisioning.
