STOCKHOLM -- Ericsson Microelectronics has introduced the PGE 60822, a new Erbium-Doped Fiber Amplifier (EDFA) with integrated control electronics and a 3.3 Volt power supply. The device can quickly be customized for optimum performance in intelligent, dynamic, optical DWDM systems. Designed for optical signal amplification over the entire C-band, the device is suitable for booster, line, or pre-amplifier use in systems or sub-systems for long haul and metro applications. Integrated control electronics and the rapid customization service enable compact, cost-optimized systems to be developed in the shortest possible time. The PGE 60822 also features low power consumption, integrated intelligence, transient suppression and flat gain over the whole C-band. It is based on the Ericsson versatile EDFA platform and compatible with complementary products from other vendors. In a separate release: Ericsson Microelectronics has introduced a new 10 Gb/s Electro-absorption Modulated Laser (EML) with excellent modulator chirp. The PGT 20406 laser module combines a continuous wave DFB laser with an electro-absorption modulator in a single chip. The unit transmits optical signals for distances up to 80 km in single channel or dense wavelength division multiplexing (DWDM) optical networking applications. The PGT 20406 laser module is ideally suited to benefit optical networking system OEMs and subsystem manufacturers. The PGT 20406 laser module will find its way into SDH/SONET, DWDM and 10 Gb Ethernet applications in both long haul and metro optical networking systems with up to 80 km link distances. A common link distance in existing 2.5 Gb/s systems is 80 km, using the PGT 20406 it is possible to replace four 2.5 Gb/s laser modules with one device without the need to alter the network infrastructure. This reduces the number of lasers and/or increases the transmission capacity in the systems. In a separate release: Ericsson Microelectronics has announced that it is developing a range of 300-pin Multi-Source Agreement (MSA) compliant 10 Gb/s transponders (SerDes transceivers). Initial models will target single channel and DWDM applications and feature 40 or 80 km reach distances. Manufacturers of optical networking equipment for long haul and metro systems will benefit from increased reliability in supply through the MSA. The transponders will feature a 10 Gb/s optical interface with transmitter and receiver, and a 16:1/1:16 MUX/DEMUX (SerDes) which will perform the conversion operations between the serial optical interface and the Low-Voltage Differential Signal (LVDS) electrical interface. The modules will contain an Electro-absorption Modulated Laser (EML), an APD or PIN photo-detector, and integrated control electronics including driver control, cooler circuitry, a clock and a data recovery unit. They will also provide a variety of alarm and monitoring features. The transponders will have a low power dissipation of typically 9.8W running off 5 V, 3.3 V and -5.2 V power supplies. These integrated, compact 102 x 89 x 13.2mm (4 x 3.5 x 0.52in), 'plug and play' solutions will significantly reduce design time and resources. The MSA presently consists of the following members: Agere, Alcatel, Opnext, Ericsson, Agilent, Mitsubishi, Excelight, JDSU and NEC. In a separate release: Ericsson Microelectronics has announced that it is developing the company's most compact Erbium-Doped Fiber Amplifier (EDFA) to date. Measuring only 70 x 45 x 10mm it is believed to be the industry's smallest EDFA. The device will benefit manufacturers of optical system or subsystems by providing reduced system costs through board space savings and low power consumption. The device is intended for single channel or narrowband applications in the C-band wavelength range where gain flattening is not required. It can be optimized to perform as a booster, line, or pre-amplifier in systems or subsystems, both in long haul and metro applications. Despite its compact size the device will include integrated input and output monitoring diodes. Ericsson AB
