Abstract: A flexible bit rate clock recovery unit (30) is provided for recovering a clock signal from an input data signal, where the input data signal is transmissible at different bit rates. The flexible bit rate clock recovery unit includes a plurality of fixed rate clock recovery units (32), where each fixed rate clock recovery units is operative at a different rate to extract an intermediary clock signal from the input data signal; a comparator (34) for generating an encoded data signal based on an amplitude characteristic of each of the intermediary clock signals, where the encoded data signal is indicative of the clock signal associated with the input data signal; and a selector (36) for selecting one of the intermediary clock signals based on the encoded data signal, thereby recovering the clock signal from the input data signal.

Abstract: A wavelength selective optical cross-connect includes a first demultiplexor feeding into individually removable modules that in turn feed a first multiplexor, such that the cross-connect is expandable and repairable on a wavelength or waveband basis. The modules desirably include multiple optical components in the optical path, with components in each module matched to others in that module to provide module-to-module variation below that of the variation in module components. The modules desirably include an additional demultiplexor and multiplexor. The modules also desirably include wavelength or narrowband amplification together with power equalization. The modules may also include a switch fabric. Alternatively, the switch fabric may be provided in the form of a separate removable switch module or modules, with various technologies employed in various switch modules, including manual switching with automatic connection discovery, with simple plug-in upgradeability to modules having automatic or remotely actuated switching.

Abstract: Disclosed is a telecommunications link having positively chirped optical signal pulses propagating in an optical waveguide fiber, at least a portion of which is characterized by a negative chromatic dispersion. An embodiment of the invention is a semiconductor laser source in combination with negative dispersion optical waveguide fiber. The source of the chirped signal pulses is selected to have predominantly adiabatic chirp as evidenced, in the case of a DFB laser, by a gain compression factor in the range of 4 x 10 m to 30 x 10 m . Eye closure penalty and bit error rate are maintained low for link lengths having cumulative dispersion parameter times distance product of the order of thousands of ps/nm. Optimum laser extinction ratio is found to be in the range of 5 to 10 dB, although extinction ratios as high as 20 dB are contemplated.

Abstract: The present invention is a modular optical switch fabric (10) that includes optical modules (100) that are inserted into an optical chassis (20) by way of plug-in electrical connectors (112, 220). Each optical module (100) includes a collimator panel (104) and a beam steering panel (106) secured to a frame member (102). The frame member (102) is configured to position the collimator panel (104) in fixed optical alignment relative to the beam steering panel (106). The modular optical switch fabric (10) is upgradeable. The optical switch fabric (10) allows users to expand the switch fabric capacity by simply adding switch fabric modules. The optical switch fabric (10) also features modules that can be replaced and repaired without causing interruptions in service.

Abstract: Disclosed is a telecommunications link having positively chirped optical signal pulses propagating in an optical waveguide fiber (52), at least a portion of which is characterized by a negative chromatic dispersion. An embodiment of the invention is a semiconductor laser source (46) in combination with negative dispersion optical waveguide fiber (52). The sourc e (46) of the chirped signal pulses is selected to have predominantly adiabati c chirp as evidenced, in the case of a DFB laser (46), by a gain compression factor in the range of 4 x (10 power of -23)x(m power of 3) to 30x (10 power of -23) x(m power of 3). Eye closure penalty and bit error rate are maintain ed low for link lengths having cumulative dispersion parameter times distance product of the order of thousands of ps/nm. Optimum laser extinction ratio i s found to be in the range of 5 to 10 dB, although extinction ratios as high a s 20 dB are contemplated.
