Huawei Unveils a New-Generation PID Solution for Metro Networks

Huawei, a leading global information and communications technology (ICT) solutions provider, unveiled a new-generation photonic integrated device (PID) solution for metro networks at the TNMO forum in London.

Huawei's new PID solution adopts advanced modulation formats and digital signal processing (DSP) technology to provide cost-efficient high-capacity transmission, including rates of 40 Gbit/s, 100 Gbit/s, 400 Gbit/s, and even higher. Leveraging industry-leading dispersion management technology, this solution 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). Furthermore, the solution is highly-integrated in that multi-service native transport is implemented on a single 2 cm2 chip.

Using the new-generation PID solution, Huawei has developed 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, effectively protecting operators' infrastructure investment.

"The surge in data traffic has created a growing demand for bandwidth on metro networks. 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," said Jack Wang, President of the Huawei Transport Network Product Line.

Huawei is a leading provider of transport services and first-class transport network products, including WDM/OTN/MS-OTN, MSTP/Hybrid MSTP, microwave and end-to-end network solutions. According to consultancy firm Ovum, Huawei ranked No. 1 in the global optical network market as of Q4 2012.
