Patent number: 7693365Abstract: Chromatic dispersion is determined based on the arrival times of different frames of data in a wavelength division multiplexed (WDM) system having an optical communication link. Namely, a first frame is transmitted on a first optical channel, which is supplied to the optical communication link. A second frame is then transmitted on a second optical channel and the transmission time difference between the two frames is obtained. At a receive end, the difference in arrival times of the two frames is measured to obtain a relative time delay between the first and second frames and used to determine a chromatic dispersion.Type: GrantFiled: February 4, 2008Date of Patent: April 6, 2010Assignee: Infinera CorporationInventor: Michael Kauffman

Publication number: 20090196615Abstract: Chromatic dispersion is determined based on the arrival times of different frames of data in a wavelength division multiplexed (WDM) system having an optical communication link. Namely, a first frame is transmitted on a first optical channel, which is supplied to the optical communication link. A second frame is then transmitted on a second optical channel and the transmission time difference between the two frames is obtained. At a receive end, the difference in arrival times of the two frames is measured to obtain a relative time delay between the first and second frames. The relative time delay is the sum of the transmission time difference and the propagation time difference (the time difference attributable to chromatic dispersion) between the two frames. Thus, by subtracting the transmission time difference from the relative time delay, the propagation time difference can be obtained.Type: ApplicationFiled: February 4, 2008Publication date: August 6, 2009Inventor: Michael Kauffman

Publication number: 20070244053Abstract: Compositions and methods disclosed herein capitalize on the discovery that rejection of a tissue graft can be inhibited using a CD40:CD154 binding interrupter, either alone or in combination with another immunomodulator or immunosuppressor. An advantageous, synergistic combination includes a CD40:CD154 binding interrupter and a CD28 signaling interrupter. An exemplary CD40:CD154 binding interrupter is an anti-CD154 monoclonal antibody, such as an antibody having the antigen-specific binding characteristics of the 5c8 monoclonal antibody. An exemplary CD28 signaling interrupter is a CTLA4-Ig fusion protein. The disclosed compositions and methods unexpectedly can be used to prolong survival of grafted tissue in a recipient host, to reverse acute graft rejection, and to attenuate immunological consequences of the failure of grafted tissue.Type: ApplicationFiled: December 12, 2006Publication date: October 18, 2007Inventors: Allan Kirk, David Harlan, David Thomas, Michael Kauffman, Linda Burkly
