Building E2E Large Bandwidth, Low Latency, Multi-Service Transport Networks

[Nice, France, July 1, 2016] Huawei unveiled a new-architecture case-shaped product OptiX OSN 1800 II in the WDM IIR forum in Nice France. Intended for metropolitan edge nodes, the product uses the cell-based unified switching architecture, the first such architecture to be used on 2 U products. With 240G ODUk/100G PKT/40G VC-4/20G VC-12 unified cross-connect capacity, OptiX OSN 1800 II is the most compact and integrated case-shaped multi-service optical transport network (MS-OTN) product in the industry.

The rapid development of services such as mobile broadband, 4K streaming media, and high-speed course-grained private line services significantly impacts metro networks. Operators face multiple challenges, including high bandwidth, low latency, and multi-service bearing on their metro networks. Downshifting to the metro network edge, MS-OTN provides massive bandwidth for multi-service access and flexible grooming of services with different granularities, achieves single-hop wavelength reach to nodes at different network layers, and reduces transmission latency.

As a large-capacity and multi-service access MS-OTN product, case-shaped OptiX OSN 1800 II is the optimal choice for operators to deal with the challenges of metro networks. Its compact 2 U size allows OptiX OSN 1800 II to be easily deployed at metro edge nodes, and its cell-based unified switching architecture achieves unified scheduling of ODUk/PKT/VC services. The unified access and cross-connect of 2 Mbit/s to 10 Gbit/s TDM and packet services address the requirements of voice, HD video, and high-speed Internet access services. This allows for unified service bearing in different scenarios, such as broadband, private line, and mobile applications. The MS-OTN product avoids the need for network device stacking, simplifies network construction and O&M, and acts as a substitute for MSTP devices after they are retired from networks.

Upon unveiling the OptiX OSN 1800 II, Huawei has built an E2E MS-OTN solution for nodes from metro edge to backbone core, enabling single-hop wavelength reach between COs and CRs. This solution vastly reduces transmission latency, covers services carried over both terrestrial and undersea cables, and allows unified network management using U2000.

Gao Ji, president of Huawei's transport network product line, emphasizes the crucial role of WDM edge devices:

"The trend of network development is that MS-OTN devices are deployed on network edges to reduce network nodes and simplify network O&M. OptiX OSN 1800 II has been developed to cater for metro edge nodes. Only with the extension of WDM devices to network edges can massive bandwidth and minimum latency be achieved, therefore breaking massive service bearing bottlenecks of metro networks."

Huawei is committed to supplying customers worldwide with the most advanced transport network solutions. As of today, Huawei's 100G solutions have served over 150 operators from more than 40 countries and regions. According to the renowned consulting firm Ovum, Huawei has maintained its leading position in the global optical network market, WDM/OTN market, and 100G market in Q1 2016.
