Huawei Unveils a New-Generation PID Solution for Metro Networks


Huawei has unveiled a new-generation photonic integrated device (PID) solution for metro networks at the TNMO forum in London. The PID uses advanced modulation formats and digital signal processing (DSP) technology to provide high-capacity transmission at 40 Gbit/s, 100 Gbit/s, 400 Gbit/s, and higher rates. The use of dispersion management technology allows the PID to make long range transmissions. This is achieved without the use of optical amplifiers and dispersion compensation modules (DCMs) or any complex design at the photonic layer. Multi-service native transport for the PID is implemented on a single 2 cm² chip.

A smart line card has also been developed for Huawei’s Hybrid MSTP products using the new PID. The card supports native and unified transport of different types of services over one port including Ethernet, ATM and TDM. Jack Wang, President of the Huawei Transport Network Product Line says: “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.”
