Patent number: 9031092Abstract: A computer system and method for transmitting LAN signals over transport systems. LAN signals are generated in any client LAN compliant interface. A transceiver receives the client LAN signal in the LAN format. The client LAN signals are not converted to a SONET transmission format at any time before reaching the transceiver. The transceiver then converts the client LAN signal to an internal electrical LAN signal before re-clocking the internal electrical LAN signal. The re-clocked internal electrical LAN signal is then re-modulated into a second LAN signal. The second LAN signal is then transmitted to a transport system.Type: GrantFiled: November 12, 2013Date of Patent: May 12, 2015Assignee: Pivotal Decisions LLCInventors: Jeffrey Lloyd Cox, Samir Satish Sheth

Publication number: 20090129774Abstract: Optical signals generated from customer premise equipment (CPE) at the edges of the metro domain networks are facilitated. The CPEs connect to extension terminals that transform the optical signal originating at the CPE into a 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 to a second primary terminal. The signal is then demultiplexed from other optical signals and transmitted 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. The signal undergoes optical-to-electrical conversion only at the extension terminals or end points, which can be located at lessee's facility. The only equipment located in lessor's facility is the primary terminal containing line amplifiers and add/drop nodes.Type: ApplicationFiled: January 26, 2009Publication date: May 21, 2009Applicant: PIVOTAL DECISIONS, LLCInventors: Pawan Jaggi, Marvin R.

Patent number: 7532782Abstract: A flexible optical circuit comprising passive or active components is provided. The flexible optical circuit includes a first optical fiber having both first and second ends, a second optical fiber having both first and second ends, a flexible substrate attached to both the first and second optical fibers where the first and second pins of the first and second optical fibers extend to at least the edge of the flexible substrate and a component coupled to the first optical fiber between the first and second ends. The component can be used passive or active. A passive component requires no electrical trace lines to activate the component and the passive component will react upon the reception of a light-wave signal. The active component will require power from the back plane before the active component can modify or affect the light-wave signal. The first and second ends of the optical fibers extend at least to the edge of the flexible optical circuit or can extend beyond the edge of the flexible substrate.Type: GrantFiled: December 18, 2002Date of Patent: May 12, 2009Assignee: Pivotal Decisions LLCInventors: William David Bragg, Peter Earl Stokes, John W.
