Huawei unveils photonic integrated device for metro networks
Huawei Technologies Co Ltd., has unveiled a new photonic integrated device (PID) aimed at metro networks at the Transport Networks for Mobile Operators forum in London, UK.
Huawei says its new PID technology adopts advanced modulation formats and digital signal processing (DSP) technology to provide cost-efficient high-capacity optical transmission, including rates of 40 Gbps, 100 Gbps, 400 Gbps, and even higher. Combined with dispersion management technology, this approach can achieve long-reach transmission of up to 80 km without the need for a complex design at the photonic layer or auxiliary units such as optical amplifiers and dispersion compensation modules (DCMs), according to Huawei. Furthermore, the device is highly integrated in that multi-service native transport is implemented on a single 2-cm2 chip.
Huawei has incorporated the PID into a smart line card for its Hybrid MSTP products. The smart line card supports the native and unified transport of different types of services (including Ethernet, ATM, and TDM) over one port, as well as smooth evolution among these services.
"The surge in data traffic has created a growing demand for bandwidth on metro networks,” said Jack Wang, president of the Huawei transport network product line. With support for multi-service transport and smooth network evolution, Huawei's new-generation PID solution helps operators build future-ready networks, while preserving the profits of traditional voice services."
