| Number | Title | Issue Date |
| 6624766 | Recovery and transmission of return-to-zero formatted data using non-return-to-zero devices Return-to-zero (RZ) formatted data is recovered and transmitted using non-return-to-zero (NRZ) devices. A NRZ clock and data recovery device (CDR) interprets the clock rate of a RZ formatted signal as twice its actual clock rate. Due to this interpretatio... | 09/23/2003 |
| 6529303 | Optical communications networks utilizing frequency division multiplexing A frequency division multiplexing (FDM) node used in optical communications networks provides add-drop multiplexing (ADM) functionality between optical high-speed channels and electrical low-speed channels. The FDM node includes a high-speed system and an... | 03/04/2003 |
| 6493131 | Wavelength-locking of optical sources A device is used to wavelength lock two optical signals to some frequency offset. A photomixer section produces a frequency test signal from the beat component of the two optical signals. The frequency of the frequency test signal reflects whether the act... | 12/10/2002 |
| 6452945 | Electrical add-drop multiplexing for optical communications networks utilizing frequency division multiplexing A frequency division multiplexing (FDM) node used in optical communications networks provides add-drop multiplexing (ADM) functionality between optical high-speed channels, and low-speed tributaries. The FDM node includes a high-speed system and an ADM cr... | 09/17/2002 |
| 6407843 | System and method for spectrally efficient transmission of digital data over optical fiber A system transmits digital data over an optical fiber at high aggregate data rates and high bandwidth efficiencies. The system includes a modulation stage, a frequency division multiplexer, and an optical modulator. The modulation stage QAM-modulates a pl... | 06/18/2002 |
| 6046838 | Automatic bias control for electro-optic modulators The bias point of an electro-optic modulator, such as an Mach-Zender modulator, is automatically controlled. A pilot signal, preferably two pilot tones at different frequencies, is applied to the modulator. The output of the modulator then contains variou... | 04/04/2000 |
