The NG-PON solution aims to overcome the challenges carriers currently face in technology selection, deployment, and evolution of optical networks. As a part of Huawei Any Media Giga Access Solution, the Flexible NG-PON solution will be showcased on the FTTH Conference held in Luxemburg, February 16 to 18, 2016, along with Huawei's 100G-PON prototype and Smart Home solution.
The new Flexible NT-PON solution will help drive development of new services such as 4K/8K video, cloud service, and Internet of Things (IoT) and signifies the advent of the Gigaband era. The access bandwidth of PON networks continues to increase, while at the same time, the single PON access mode that mainly provides home broadband services is being replaced by various new application scenarios, including passive optical LAN (POL)-based all-optical campus, private line access for small- and medium-sized enterprises (SMEs), small office and home office (SOHO) service, mobile backhaul, and network wholesales for virtual network operators (VNOs). This expanding range of services places a variety of benchmarks on PON networks. For example, home broadband services mainly require a smooth downstream transmission; SME private line services require symmetric upstream and downstream bandwidths; and mobile backhaul services require time synchronization, low delay, and dedicated high bandwidth.
Carriers' optical networks are evolving from PON, 10G-PON (including asymmetric xG-PON and symmetric xGS-PON), to 40G TWDM-PON. During this network evolution, carriers need to balance the requirements for service bandwidth, device costs, technology selection, and future network development. To achieve this balance, Huawei is launching the Flexible NG-PON solution based on the MA5800 intelligent aggregation OLT platform. This solution enables one board to support multiple xG-PON, xGS-PON, and 40G TWDM-PON optical module configurations. Compared with traditional solutions, the Flexible NG-PON solution features the all-in-one, on-demand deployment, and smooth evolution. All-in-one indicates that the product supports the standardized of all-scenario hardware, that is, the product uses different optical modules to satisfy the requirements of different access modes. This reduces the number of required spare parts as well as O&M costs. On-demand deployment and smooth evolution indicate that carriers can deploy 10G-PON networks at the beginning, and replace the optical modules to smoothly upgrade their 10G-PON networks to 40G TWDM-PON if future bandwidth requirements increase.
Huawei's Flexible NG-PON solution inherits the distributed architecture and multi-service virtualization of the MA5800 platform. Therefore, this solution allows the logical fragmentation of device and network resources, supports network opening up and wholesale, and ensures the agile deployment of new services.
