Lucent Technologies Announces First 40-Gigabit-per-second Optical Receiver for Next-generation Optical Networking Systems.Business Editors, Hi-Tech Writers MUNICH, Germany--(BUSINESS WIRE)--September 4, 2000 Receiver enables systems to operate up to four times faster meeting capacity demands in high-speed optical transport backbone networks Lucent Technologies (NYSE NYSE See: New York Stock Exchange : LU) Microelectronics Group today announced its first 40-gigabit-per-second (Gbit/s) optical receiver - a major optoelectronic component in next-generation fiber-optic communications systems. By offering a component that operates up to four times faster than current-generation devices, Lucent can enable designers to build the systems of tomorrow that will meet the demand for increased capacity in high-speed optical transport backbone networks. The device, called the R768, receives and converts streams of light pulses carrying voice, video and data signals into electrical signals. Designed by Bell Labs, the R768 receiver uses a waveguide waveguide, device that controls the propagation of an electromagnetic wave so that the wave is forced to follow a path defined by the physical structure of the guide. positive intrinsic negative (PIN) detector to convert the light into electrical current. It then uses a multi-functional integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for (IC) as a preamplifier Preamplifier A voltage amplifier suitable for operation with a low-level input signal. It is intended to be connected to another amplifier with a higher input level. to strengthen the received signal for further processing. The R768 can be used in long-haul and submarine transport networks and is ideal for line terminal and digital video equipment, and very high-speed router-to-router connections. Lucent is exhibiting the R768 and its broad line of other optoelectronic components and ICs here at the 26th European Conference on Optical Communication (ECOC ECOC European Conference on Optical Communications ECOC Error Correcting Output Codes ECOC Experimental Combat Operations Center ECOC Enhanced Combat Operation Center ECOC Emotional Cycle of Change ) in Munich, Germany, September 4-6. "Lucent's new receiver is the second product to join our line of 40-Gbit/s optoelectronic components," said Kim Trapp, marketing director for Lucent's Microelectronics Group. "Last year we introduced our 40-Gbit/s 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. , which is still the highest speed-device commercially available for optical transport systems. This latest product maintains us as a front-runner optoelectronic components supplier delivering next-generation components addressing the ever-growing demand for more capacity." The R768 receiver consists of a high-speed photodetector A device that senses light. It uses the principle of photoconductivity, which is exhibited in certain materials that change their electrical conductivity when exposed to light.

The receiver is manufactured in a compact 16-pin package, and requires only a six-volt power supply. It is fully operational through the L-band (1.6-micron) wavelength range. Samples of the R768 are expected to be available for a limited number of customers by the fourth quarter of 2000 with initial-volume production expected by the second quarter of 2001. Unit pricing will be approximately US$10,000. For more product information, customers may call the Microelectronics Group Customer Response Center, 1-800-372-2447, Dept.

Lucent Technologies Microelectronics Group is the $4 billion world leader in semiconductors for communications applications. Lucent has announced it will spin off the Microelectronics Group as an independent company that will include its optoelectronics and integrated circuits divisions. The spin-off, slated for completion by the summer of 2001, will create the only major stand-alone semiconductor company that can offer end-to-end networking solutions that address the convergence of photonics and electronics based on leadership in both integrated circuits and optoelectronic components. The new company will also provide wireless computer networking system solutions through its ORiNOCO(TM) product line.
