GBaud polarisation diversity x-QAM signals featuring highly reliable results for common mode rejection ratio, linearity and optical input power.
This means the device can be used in next generation long haul transmission systems at data rates of 400 Gbit/s and beyond. At the same time, the BPDV3120R is well suited for T&M applications as well as ongoing R&D activities at high Baud rates.
“While 100G coherent systems are being widely deployed today, we can already see that 400 Gbit/s or even 1 Tbit/s systems will be required in a few years to support the continued exponential growth of data traffic in mobile and fixed networks,” says u²t Photonics CEO Andreas Umbach. “Our 70 GHz balanced photodetector provides one of the key building blocks that will enable systems providers to build and deploy systems operating at 400G per wavelength or higher.”
u²t started sampling the BPDV3120R in March 2013 and will start its production in June.
u²t Photonics AG is a privately-held company headquartered in Berlin, Germany. It offers a comprehensive and fully TELCORDIA qualified portfolio.
The compact devices, shown above, measure 2.4 x 3 x 0.8 mm.
MEMS Vision combines silicon technolgy with SiC for sensors
The MVH3000D product line of tiny chips is designed to fulfil the needs of a wide range of applications and markets. These include consumer electronics, health & fitness, industrial, building automation, appliances, and wireless sensing (the internet of things)
MEMS Vision, a supplier of MEMS-based solutions to the global sensing market has launched its most advanced MVH3000D series of digital relative humidity (RH) and temperature (T) sensing chips.
The company maintains that a unique combination of features, programmability, and high performance specs, ensures the most competitive value in the industry.
The high accuracy MVH3001D chips have a ±1.5 percent RH accuracy.
MEMS Vision also says unmatched robustness, reliability, and durability is achieved through the proprietary use of SiC to build and protect the miniature sensors.
These sensors also have high electromagnetic
The MVH3000D series features four products, offering a comprehensive choice of RH accuracies, from ±1.5 percent RH to ±3.8 percent RH, and of temperature accuracies, from ±0.20C to ±0.30C.
International customers are currently sampling these new products, and an evaluation kit is now available to experience and assess the full capabilities of these sensors, along with a set of reference designs.
NeoPhotonics opens sales and R&D office in Moscow
The firm’s expansion targets high-speed indium phosphide “Core” network applications across Russia and Eastern Europe
NeoPhotonics Corporation, a designer and manufacturer of InP photonic integrated circuit ( PIC), based optoelectronic modules and subsystems for bandwidth- intensive, high speed communications has opened sales and R&D office in Moscow.

interference protection and are claimed to be the only chips in this class to feature grounded metallic shields.
Apart from the wide range of allowable supply voltages (1.8V - 5.5V), the resolutions of the RH & T readings can be set independently from 8 to 14 bits, for a total of 16 different combinations.
The RH response time is typically 6 seconds for humidity measurements and have a low power consumption of 2μW average power for one RH+T measurement per second in the lowest power mode (1.8V, 8-bit resolution).
Very high temperature accuracy – a temperature accuracy of ±0.20C is guaranteed, over the wide range from -100C to 800C (models MVH3001D and MVH3002D).
