TriQuint Semiconductor, Inc., a leading RF products manufacturer and foundry services provider, has expanded its optical infrastructure portfolio with five new transimpedance amplifiers (TIA), enabling the company to now serve both transmit and receive portions of high performance optical networks.
The new product family complements TriQuint’s industry-leading modulator driver portfolio for 10, 40, 100 Gb/s and next-generation 200G/400G systems.
TriQuint’s new TIAs offer performance benefits tailored to key design requirements that support 40G, 100G and emerging optical systems. TriQuint’s new products are part of a recent technology acquisition from Micram Microelectronic GmbH.
“This new amplifier family perfectly complements our optical modulator drivers. We’re sampling next-generation products and receiving positive feedback from numerous customers,” said James L. Klein, TriQuint Vice President and General Manager for Infrastructure and Defense Products. “Our new TIA family serves today’s fastest networks as well as the higher modulation needs of future optical broadband systems.”
The continual worldwide growth in smartphone and tablet data traffic as well as other broadband mobile devices is driving global network capacity expansion. Optical networks remain the most economical means for long-distance, high-speed data transfers across wired and mobile device networks. Infonetics Research commented recently that the global optical market is expected to grow in 2013, with expansion primarily in North America, China, Europe and the Middle East.
“Our conversations with equipment providers continue to trend positive, particularly in North America where 100G spending is about to ramp…Meanwhile, there are positive rumbles in the EMEA region; preliminary results show that 2013 will be a huge year for 100G in China; China is about half of the global 40G WDM market,” said Infonetics Principal Optical Analyst, Andrew Schmitt, in a February 2013 report.
TriQuint’s first TIA release includes five new silicon germanium (SiGe) amplifiers for use in optical networks ranging from very-short-reach to metro- and long-haul. The products are announced in conjunction with the OFC/NFOEC conference and exposition in Anaheim, CA (March 19-21) and complement TriQuint’s wide selection of surface-mount optical modulator drivers.
