RICHARDSON, Texas & ANAHEIM, Calif. -- OFC 2002 -- Chorum Technologies, a leading provider of all-optical processors and subsystems for low-cost, high-capacity networks, today announced it has expanded its PolarWave(TM) family of products to include the new PolarTune(TM) Micro Variable Optical Attenuators (Micro VOA). These miniature versions of the Variable Optical Attenuator (VOA) are the industry's smallest solid-state electronic VOAs. Based on Chorum Technologies' patented proprietary liquid crystal technologies and manufacturing processing, the Micro VOA series supports real-time power attenuation and regulation. Effective in both dynamic and set-and-forget optical networks, these devices provide low insertion loss, low polarization dependence loss (PDL), fast response time and a wide dynamic range with solid-state reliability - all in a very small footprint. "Our new Micro Variable Optical Attenuator provides the highly reliable control of optical power level necessary for the next generation of optical systems in a very small, board-mounted package that our customers require," said Scott Grout, Chorum Technologies' president and CEO. Chorum Technologies will demonstrate its PolarWave(TM) products, including a live demonstration of the Micro Variable Optical Attenuator, at OFC exhibition booth #1739. In a separate release: Chorum Technologies, a leading provider of all-optical processors and subsystems for low-cost, high-capacity communications networks, today announced it has expanded its PolarWave(TM) family of products to include the new PolarModule(TM) Variable Mux/Demux Modules, intelligent optical subsystems for integrated signal power control and multiplexing/demultiplexing. Developed through integration of Chorum Technologies' proprietary free-space diffraction grating and high-density liquid crystal arrays, Variable Mux/Demux Modules (VMux) provide individual channel optical power control, while multiplexing or demultiplexing optical channels. Designed for channel equalization and pre-emphasis, the VMux provides a low cost, low loss solution for intelligent control of optical signal power. The next generation of dynamic, intelligent optical networks requires subsystems designed to integrate multiple functionalities at very low cost. The VMux fulfills these requirements by providing sophisticated, intelligent optical power level control in a highly integrated optical module. Interface with overall system control algorithms is accomplished via a memory-mapped 16-bit dual port RAM. In a separate release: Chorum Technologies, a leading provider of all-optical processors and subsystems for low-cost, high-capacity networks, today announced it has expanded its PolarWave(TM)family of products to include the new PolarTune(TM)Dispersion Compensation Unit. Based on Chorum Technologies' proprietary technology, the Dispersion Compensation Unit (DCU) compensates the link dispersion of different standard fibers. Designed as a drop-in replacement for current dispersion compensating fiber (DCF) products, the DCU offers competitive performance in a significantly smaller package (roughly 1/10th the volume). In addition, this unique solution exhibits no non-linear optical power effects. "The DCU is the first in a line of new dispersion compensation products and is Chorum Technologies' solution for today's network dispersion issues," said Scott Grout, Chorum Technologies' president and CEO. In a separate release: Chorum Technologies, a leading provider of all-optical processors and subsystems for high-capacity networks, today announced it has expanded its PolarWave(TM) family of products to include the new PolarCast(TM) 25GHz DQ Series of passive Optical Slicer(TM) Filters for high bandwidth, 10 Gb/s optical networks. Based on Chorum Technologies' proprietary technology, the 25GHz DQ Series of Slicer Filters is an athermal interleaving device that provides 25GHz channel spacing with minimal impact on system bit error rate. The next step for ultra-high bandwidth optical networks, 25GHz channel spacing at high data rates requires wide passbands, high isolation and very low dispersion. The 25GHz DQ Series Slicer Filter meets these requirements without active temperature control. "The 25GHz DQ Series Slicer Filter is designed to meet the challenges of OC-192 transmission at 25GHz channel spacing, further enabling bandwidth in metro, long-haul and ultra long-haul optical networks," said Scott Grout, Chorum Technologies' president and CEO.
