Based on the requirements of the broadband access network in the Chinese market and the characteristics of GPON products, along with current deployment practices, it is recommended to adopt the FTTH (Fiber to the Home) construction model.

This model enables ultra-high bandwidth for end users, supporting rich functionalities such as IP networking, cable TV, and fixed-line telephony, delivering the best user experience.

FTTH Network Area Division

The FTTH network is part of the access network and should align with the planning approach of the access network. Planning is conducted through area divisions, with each division typically corresponding to an access network service area. An access network service area is the region covered by the backbone network of an access network. The service area is usually centered around a central office and may feature single-office or dual-office coverage. Once the planning for FTTH nodes and ODN networks within each access network service area is complete, comprehensive considerations, including network resource planning and economic evaluations, can be conducted at the broader local network level.

Key Services Provided by FTTH Networks

The FTTH system serves as an integrated access solution, offering high bandwidth and QoS assurance. It can carry various services, including Ethernet/IP services, voice services, and video surveillance, fulfilling the requirements of "Triple Play."

Key services include:

Data Services: FTTH provides bandwidth exceeding 30 Mbps, sufficient to meet the demands of Ethernet/IP-based applications over a long period. These include internet access, P2P, file downloads, online gaming, and more.

Voice Services: FTTH supports voice services, including VOIP-based softswitch telephony (and value-added services) and traditional telephony via 64kbit/s circuit emulation. From a technical perspective, softswitch-based implementations will become a mandatory feature for FTTH systems.

CATV Services: FTTH supports digital and high-definition cable television. GPON’s efficient bandwidth utilization significantly improves upstream video data efficiency while providing higher downstream bandwidth to support high-definition terminal demands.

For residential customers, FTTH primarily delivers voice, data, and video services. For enterprise customers, it focuses on voice, data, and surveillance services.
