• Customer Demand

Facing the pressure of explosive growth of mobile data traffic, operators have accelerated the pace of commercial deployment of LTE network to attract more subscribers in the LTE era, and at the same time to ensure market share and gain revenue.LTE is limited by its frequency band system, the coverage within the city is smaller than that of the traditional 2G/3G.Small Cell is an important part of LTE HetNet, and most operators choose to deploy a large number of Small Cell backhaul methods internationally. Most operators choose to deploy a large number of Small Cell micro base stations to obtain rapid network capacity improvement and ensure network coverage, so as to provide excellent user experience and enhance their market competitiveness.

The large-scale deployment of Small Cell requires the existing network to have rich mobile backhaul resources, and at the same time requires the backhaul bearer network to have high network bandwidth, reliability, clock time synchronization, flexible power supply capacity and high network reliability requirements, the use of traditional backhaul platforms is no longer feasible. In order to protect network revenue, mobile operators need to consider choosing cost advantageous, flexible and reliable technology to carry Small Cell backhaul.

The xPONFTTx optical access network that has been massively deployed in the existing network has a natural advantage in carrying Small Cell, its coverage area is highly consistent with the coverage demand of Small Cell, and all aspects of the network capacity are in line with the requirements of LTE network backhaul, which is extremely suitable for Small Cell backhaul in a bearer access method.

The Solution

Meanwhile, based on a deep understanding of LTE network requirements and an in-depth analysis of LTE Small Cell application scenarios, ZTE has launched the ZXA10xPON passive optical access network bearer LTE Small Cell solution, which provides high-quality service QoS guarantee and good user experience for LTE backhaul.　　

ZXA10xPON passive optical access system provides a series of FTTx solutions to meet the needs of indoor and outdoor application scenarios for Small Cell deployment in areas with insufficient LTE network coverage and capacity, supporting coverage and capacity expansion in indoor scenarios, including homes, enterprises, and high-rise buildings, as well as hotspots, blind splitting, and urban fringe and rural coverage in outdoor scenarios. Adapt to the backhaul demand of micro base station deployment in LTE era. It meets the backhaul capability of the access network for operators to flexibly and quickly deploy and carry out services, and provide low-cost large bandwidth and multi-service support.

ZTE xPONFTTx has a series of system and terminal products. The system equipment supports various uplink and downlink protection functions, 1588V2 and synchronous Ethernet, 1PPS+ToD and other clock time mechanisms, and ONUs can provide integrated low-cost SFP module ONTs, convergent multiport ONUs, and outdoor-type ONUs with strong environmental adaptability, which can be flexibly deployed in accordance with different scenarios of LTE micro-base stations. The equipment can be deployed flexibly according to different scenarios of LTE micro base stations, and the equipment can be managed in a unified way with decentralized and sub-domained and end-to-end visualized interfaces, which can satisfy a variety of application scenarios of Small Cells, and meet the requirements of LTE bearer in terms of latency, QoS, clock synchronization, power supply and other indexes. At the same time, ZTE's FTTx products support smooth evolution according to the technology and continue to meet the development needs of wireless broadband networks.

Customer Benefits

• Utilizing the existing network and saving bearer resources The FTTx network deployed on a large scale in the existing network is highly consistent with the areas that Small Cells need to cover, and the use of the FTTx access network can flexibly and quickly provide on-demand deployment of Small Cells with significant cost advantages, fast return on investment, low deployment costs, and low bearer resource occupation.

• Provide large bandwidth access to protect the user experience xPON technology matches the development of wireless broadband access technology, from EPON/GPON to 10G PON to next-generation PON, providing GE/10GE/n*10GE access bandwidth carrying capacity, its technological stage of development and bandwidth capacity to meet the 3G/4G and subsequent 5G mobile backhaul bandwidth requirements, and continue to provide a good user experience. user experience.

• High-precision Clock Transmission to Ensure the Synchronization Requirements of Base Stations FTTx network can provide 1588V2, Synchronous Ethernet and 1PPS+ToD for clock time synchronization, as well as the clock synchronization defined by the PON system itself according to the needs, which can well meet the synchronization requirements of Small Cell Base Stations in complex installation environments.
• Refined Hierarchical QoS to Ensure Priority Forwarding of LTE Services The FTTxPON system can provide rich and flexible QoS scheduling mechanisms at the port, user and service levels to ensure priority forwarding of Small Cell services and improve user experience.

• Perfect Service Protection Capability, Providing Comprehensive Protection for Service and Network FTTxPON network can provide rich protection mechanism, adopting Type B, Type C and other protection modes to provide redundant protection for PON ports on OLTs, trunk cables, branch cables, and ONTs; meanwhile, the uplink ports support various protection modes such as LACP, ring network, and MSTP, and can be flexibly selected for general hotspot and important area protection according to the needs. At the same time, the uplink port supports LACP, ring network, MSTP and other protection modes, which can be flexibly selected to carry the protection of ordinary hotspots and important regional micro base stations and macro stations.

• Unified Management Platform, Helping LTE Bearer Intelligent Operation and Maintenance PON system provides end-to-end intelligent operation and maintenance system, providing convenient daily network maintenance and rapid fault location and processing, integrating equipment management, performance statistics, fault diagnosis and other functions, reducing the burden of operation and maintenance personnel, and solving the operation and maintenance problems of Small Cell network.
