Opto Speed launches 5-lead 2.5Gbit/s PIN-TIA TO cans for smart transceiver applications
January 14, 2003
ZURICH -- Opto Speed today announced it has developed 2.5Gb/s PIN-TIAs with single-ended and differential outputs. The modules are either available in four- or five-lead TO coaxial packages with a lensed cap or in LC or SC receptacles and are operated from a single 3.3V or a 5V supply. The differential output five-lead 2.5Gb/s PIN-TIA achieves a sensitivity of -25dBm and a dynamic range of more than 25dB. These high-sensitivity modules which also offer a power monitor function are very well suited as basic building blocks for optical Smart Transceivers for a wide range of applications including OC-48/STM-16 SONET/SDH or 2.125 Gb/s fiber channel. The modules comprise a high-speed top-illuminated InGaAs/InP pin photodiode with a diameter of the active area of 75 micrometers and a hybrid low noise transimpedance amplifier. Besides its differential data output, which can be (AC-coupled!) loaded with 50 Ohm, the module features a monitor output, which provides a current that is directly proportional to the RMS value of the input photocurrent of the photodiode. Sample shipment of the PX4 family of TO-can packaged 2.5Gb/s PIN-TIAs begins at the end of January, and Opto Speed expects to market them on a large scale and very competitively priced already in the first quarter of this year. The 2.5Gb/s PIN-TIAs will also be available as receiver optical subassemblies (ROSAs) and receptacles upon request and can be delivered within two to four weeks. "This new effort, to deliver Opto Speed's high-performance 2.5Gb/s photodetectors packaged with TIAs in advanced five-lead TO cans, builds upon Opto Speed's commitment to serve its customers with state-of-the-art optoelectronic modules and supports them to be advanced to its competitors", said Dr. Markus Blaser, Product Line Manager Photodetectors of Opto Speed.
