Fiber to the Home Construction Plan for Villa Areas

1.                      Overview

With the rapid development of the Internet and global IP networks, broadband and broadband based service access has become the development trend of the entire access network, and convergence is also the inevitable trend and goal of communication network development. The copper cable access technology currently used in access networks cannot meet the requirements of high bandwidth, long distance, and anti-interference. With the development of fiber to the home technology and the implementation of NGN soft switching (VOIP) technology, network integration based on IP networks has been accelerated. For community access, a fiber optic system can provide users with the necessary data, broadband services such as online gaming, and voice calling needs of some customers, achieving the integration of telephone and data networks.

3.                      Solution advantages

(1) Provide end-to-end business solutions to meet various access scenarios and applications.

Beijing Ruiguang Jiyuan Digital Technology Co., Ltd. can provide a full range of products required for EPON systems, including central end equipment, remote access equipment, ODN engineering construction, broadband access service systems, and softswitch systems. Provide comprehensive solutions for video, VOIP, and Ethernet services. The BE series EPON solution can be applied to the access layer construction of FTTH, FTTB and other networking modes. In newly built smart grid communities, EPON systems can be used to provide customers with high bandwidth, long-distance and wide coverage networking access.

(2) Provide a full range of EPON optical access products to meet various networking needs.

The BE series EPON products are independently developed by Beijing Ruiguang Jiyuan Digital Technology Co., Ltd. The local OLT equipment BE3000E has a large capacity backplane crossover capability, supports upstream 8GE ports, supports 1+1 protection for management disks, supports 1+1 protection for power disks, supports 48 PON connections in a single rack, and can be configured with different numbers of interfaces according to requirements to meet applications of different networking scales. Remote ONU equipment, with dedicated ONU BE20U series for industrial environments, providing RS232/485 interfaces and FE interfaces; There are also ONUs such as BE11U/12U/13U used for public networks, which can provide various service interfaces such as CATV, PATS, and FE. There is also a suitable FTTB application scenario BE20U-M2424S, which can provide multiple POTS and FE interfaces.

(3) The powerful QoS guarantee capability provides a foundation for multi service bearer.

The BE EPON system supports end-to-end network wide QoS solutions. Support two-level scheduling of OLT and ONU, providing QoS assurance by distinguishing different services and users. Support packet filtering, redirection, flow mirroring, traffic statistics, traffic supervision, port queue scheduling, port speed restriction, priority policy, and VLAN change policy based on flow rules; Supports CoS (802.1p), stream priority, multiple scheduling methods such as SP, WRR, SP+WRR, and supports 8 priority queues. Through various mechanisms

The application ensures QoS for users and provides a foundation for multi service bearer for EPON systems.

(4) Provide comprehensive network management functions and automatic business distribution solutions.

Tmaster 2000 is a unified network management platform for integrated access products of Beijing Ruiguang Jiyuan Digital Technology Co., Ltd. It supports various performance statistics functions of OLT and ONU devices in EPON systems for network maintenance and diagnosis. The network management system supports fault diagnosis functions for EPON networks, including various alarm detection and loopback diagnosis functions, and supports the handling of alarm events such as Dying Gas. TMaster2000 provides unique SMS alert notifications, which can be sent to the operation and maintenance personnel's mobile phones via SMS when network devices fail, allowing them to quickly obtain fault information.

(5) Provide comprehensive security assurance mechanisms and high reliability designs.

The BE series products meet the security requirements of telecommunications services and have conducted in-depth research and application of security protocols, fully ensuring system security and user access security. Reliability indicators have been considered in various aspects such as system design, hardware design, and network design to fully ensure the normal operation of the equipment.

4.                      Provide a solution for the passage of the intelligent villa area

The solution for providing fiber to the home intelligent villa area channel by Beijing Ruiguang Extreme Far is as follows, combined with the actual deployment of the operator's business and user needs.

Application diagram of intelligent villa area 1: Two GE ports connected to a network switch

Application diagram 2 of intelligent villa area: Two GE ports connected to BRAS and softswitch servers respectively

In the scheme shown in the above figure, the providers of telephone and broadband services are China Mobile.

Mobile operators provide telephone service access and broadband access respectively. The two upstream GE optical interfaces in the residential power distribution room are directly connected to the operator's Ethernet switch, and the Ethernet ports of the switch are respectively connected to the softswitch server and BRAS server. Among them, telephone services are directly connected to the operator's softswitch server through 100Mbps or 1G Ethernet ports, and the operator provides telephone services, including billing, dialing, etc. Broadband services are connected to the broadband access server (BRAS) of the operator through 100Mbps or 1G Ethernet ports, and the operator provides broadband services, including authentication, authorization, aggregation, bandwidth partitioning restrictions, billing, and other functions.

The above operator provides two access methods. As shown in Figure 1, two GE ports are simultaneously connected to one operator switch, which can access BRAS and softswitch servers. Under this method, user bandwidth can be fully guaranteed, while ensuring normal communication of telephone services under the condition of occupying a small amount of bandwidth. As shown in Figure 2, two GE ports are connected to a BRAS and a softswitch server respectively. In this way, the bandwidth of the GE port connected to the VOIP softswitch server is a bit wasteful because telephone services occupy very little bandwidth. This proposal suggests using the scheme shown in Figure 1.

In this scheme, VLAN division and priority setting are carried out for user telephone services and broadband services, with telephone services having higher priority, ensuring that the isolation of telephone services and broadband services does not affect each other. At the same time, in order to ensure that users have a relatively high Ethernet bandwidth, it is recommended to provide two GE optical interfaces on the operator's side. These two optical interfaces can be simultaneously connected to Ethernet switches or separately connected to BRAS servers and softswitch servers, thereby providing broadband and telephone services.

Provide one OLT device in the residential power distribution room, which provides 40 PON interfaces in the downstream and 2 GE optical interfaces in the upstream.

According to the demand of 1000 users and the requirement of 1:32 splitting, 32 PON interfaces are needed. However, considering the redundancy of actual construction, 8 spare PON interfaces are provided.

Use a 1:32 splitter device in the distribution box of the villa area, and based on actual construction conditions and proximity principles, use one splitter for every 32 users.

On the user side, use the ONU device installed in the household, which provides 4 100Mbps Ethernet interfaces and 2 telephone interfaces.
