Patent number: 9337934Abstract: A coherent receiver comprises an ingress signal path having an ingress line-side interface, and an ingress host-side interface. The ingress signal path is configured to receive an analog signal vector at the ingress line-side interface, to demodulate the analog signal vector, and to output a digital data signal at the ingress host-side interface. The coherent receiver also comprises clock and timing circuitry configured to receive a single reference clock signal and to provide a plurality of modified ingress path clock signals to different components of the ingress signal path, the plurality of modified ingress path clock signals derived from the single reference clock signal and the plurality of modified ingress path clock signals having different clock rates. The receiver, transmitter, or transceiver can operate in a plurality of programmable operating modes to accommodate different modulation/de-modulation schemes, error correction code schemes, framing/mapping protocols, or other programmable features.Type: GrantFiled: November 29, 2013Date of Patent: May 10, 2016Assignee: ClariPhy Communications, Inc.Inventors: Oscar Ernesto Agazzi, Diego Ernesto Crivelli, Paul Voois, Ramiro Rogelio Lopez, Jorge Manuel Finochietto, Norman L.

Patent number: 9136942Abstract: A receiver for a communications link includes a receiver module and a host receiver. These two components can be tested independently. In one embodiment, the receiver module is characterized with respect to noise and distortion. The noise performance can be determined by comparing input and output signals of the receiver module, to determine the relative noise of the receiver module. The distortion performance can be determined by comparing the distortion of input and output signals of the receiver module, using a reference host receiver that includes an equalizer. The host receiver can be tested by using a reference receiver module.Type: GrantFiled: July 29, 2013Date of Patent: September 15, 2015Assignee: ClariPhy Communications, Inc.Inventors: Thomas A.

Patent number: 9071364Abstract: An optical communication system provides coherent optical transmission for metro applications. Relative to conventional solutions, the optical communication system can be implemented with reduced cost and can operate with reduced power consumption, while maintaining high data rate performance (e.g., 100 G). Furthermore, a programmable transceiver enables compatibility with a range of different types of optical networks having varying performance and power tradeoffs. In one embodiment, the optical communication system uses 100 Gb/s dual-polarization 16-point quadrature amplitude modulation (DP-16QAM) with non-linear pre-compensation of Indium Phosphide (InP) optics for low power consumption.Type: GrantFiled: October 18, 2012Date of Patent: June 30, 2015Assignee: ClariPhy Communications, Inc.Inventors: Paul Voois, Diego Ernesto Crivelli, Ramiro Rogelio Lopez, Jorge Manuel Finochietto, Oscar Ernesto Agazzi

Patent number: 8009981Abstract: A transmitter for a communications link is tested by using a (software) simulation of a reference channel and/or a reference receiver to test the transmitter. In one embodiment for optical fiber communications links, a data test pattern is applied to the transmitter under test and the resulting optical output is captured, for example by a sampling oscilloscope. The captured waveform is subsequently processed by the software simulation, in order to simulate propagation of the optical signal through the reference channel and/or reference receiver. A performance metric for the transmitter is calculated based on the processed waveform.Type: GrantFiled: January 4, 2010Date of Patent: August 30, 2011Assignee: ClariPhy Communications, Inc.Inventors: Norman L.
