Agere Systems Announces Industry's Lowest-Voltage, Highest Bandwidth 40 Gigabit-Per-Second Modulator for Optical Networks.Business Editors ALLENTOWN, Pa.--(BUSINESS WIRE)--May 29, 2001 Agere Systems Agere Systems Inc. was an integrated circuit components company based in Allentown, Pennsylvania, in the Lehigh Valley region of Pennsylvania, in the United States. Effective April 2, 2007, it was merged into LSI Corporation. (NYSE NYSE See: New York Stock Exchange : AGR AGR advanced gas-cooled reactor .A) today announced the industry's lowest-voltage, highest-bandwidth lithium niobate Lithium niobate (LiNbO3) is a compound of niobium, lithium, and oxygen. It is a colorless solid that is insoluble in water. Its melting point is 1257 °C and its density is 4.65 g/cm³. Its CAS number is []. modulator Modulator Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. for use in 40 gigabit-per-second (Gbit/s) optical networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. systems. With this component, systems makers can more economically design a system that delivers error-free, highly accurate performance. The device requires only a 2.5 volt drive (referenced at 1 gigahertz) and has a guaranteed minimum bandwidth of 30 gigahertz. Called the 2625C, the device converts steady, or continuous wave (CW), laser output into high-speed light pulses that transmit voice, data and video signals over fiber optic cables. Modulators are placed externally to the CW laser source in an optical networking system. Agere's modulator represents a major performance improvement in 40 Gbit/s technology. Drive voltage is one of the most critical parameters in high-speed modulator performance, and is required to switch the device from "full on" to maximum attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. , or "off." The combination of high speeds and peak-to-peak voltage swings typically makes it difficult for external drive electronics to effectively manage signal transmissions at low voltages. With Agere's solution, systems manufacturers can reduce the voltage requirement for modulator drivers while extracting the maximum bandwidth from the modulator. Unlike other low-voltage offerings that operate with bandwidths of less than 30 Ghz, Agere's modulator ensures better eye patterns and lower bit-rate errors, contributing to a more robust system design. "The tradeoff in reducing the required drive voltage is usually lower bandwidth, but Agere has achieved this power reduction without affecting bandwidth or cost," said Ken Newton, senior product manager at Agere Systems. "Agere's modulator exhibits none of the signal degradation problems that plague lower-bandwidth products." The modulator uses a "push-pull" configuration that permits chirp tunability, allowing systems manufacturers to optimize the device to their unique system requirements To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer system. These pre-requisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. . Agere's expertise in lithium niobate technology -- which ensures fast switching speeds and stable performance -- will allow the company to manufacture the modulators in high volume. "Agere has a long history in developing and manufacturing high-speed lithium niobate modulators," said Newton. "We've shipped more 10-gigabit modulators than any other company." The new 40 Gbit/s modulator is suitable for dense wavelength-division multiplexed systems used in high-speed or short-range digital networks operating up to SONET OC-768 and SDH (Synchronous Digital Hierarchy) The European counterpart to SONET. See SONET. SDH - Synchronous Digital Hierarchy STM-256 rates. Agere is currently sampling the 2625C, and expects to deliver production quantities by the fourth calendar quarter of 2001.
