Patent number: 7460297Abstract: A method and apparatus for adjusting the tilt of an inline amplifier. A controller reads the power of an amplifier twice. Then, if there is a change in power, a difference is calculated by subtracting the first power from the second power. A tilt correction is calculated by multiplying the change in power by a negative constant. The system then adjusts a gain control device by the tilt correction. Because of the simplicity of the algorithm and location of the controller, adjustments can be made to the gain tilt within approximately 100 ?s and system failures can be avoided.Type: GrantFiled: August 31, 2006Date of Patent: December 2, 2008Assignee: Pivotal Decisions LLCInventor: Michael H. Eiselt

Publication number: 20070104489Abstract: The invention facilitates optical signals generated from customer premise equipment (CPE) at the edges of the metro domain networks. The CPEs are connected to extension terminals that transform the optical signal originating at the CPE into a suitable format for long haul transmission. The optical signal then propagates to a primary terminal where the signal is multiplexed with other optical signals from other extension terminals. The multiplexed signals are then transmitted over LH or ULH network to a second primary terminal where the signal is then demultiplexed from other optical signals and transmited to the proper extension terminal. At the extension terminal, the demultiplexed optical signal is transformed from its LH format back into a format suitable for inter-connection to a CPE. Using this architecture, the signal under goes optical-to-electrical conversion only at the extension terminals or end points. These end points can be located in lessee's facility.Type: ApplicationFiled: August 31, 2006Publication date: May 10, 2007Applicant: Pivotal Decisions, LLCInventors: Pawan Jaggi, Marvin Young, William Bragg
