In extreme cases, too strong light may cause damage to the FTTR device.

然而,上述组网方式为实现最优家庭千兆光网性能,以及避免FTTR设备的损坏,需要在分光器外再次增加-5dB或者-15dB光衰减器,增加了组网成本和智家工程师施工时长。However, in order to achieve optimal home Gigabit optical network performance and avoid damage to FTTR equipment, the above-mentioned networking method needs to add a -5dB or -15dB optical attenuator outside the optical splitter, which increases the cost of networking and the construction of smart home engineers. duration.

Promote network perception and customer service to be upgraded to high quality, diversification, and intelligence.

现今的千兆时代,组网方式已成为影响网络品质家庭体验的最大瓶颈。“光猫+路由器”的传统组网模式下,Wi-Fi信号覆盖区域有限,会出现网速慢、应用卡顿的情况,在大平层或多层别墅场景下尤甚。而FTTR全屋智能千兆组网是当前业界唯一可以实现室内全光千兆覆盖的终极解决方案。In today's Gigabit era, networking methods have become the biggest bottleneck affecting network quality and home experience. In the traditional networking mode of "optical modem + router", the Wi-Fi signal coverage area is limited, and the network speed will be slow and the application will be stuck, especially in the scenario of large flat-floor or multi-story villas. FTTR whole-house intelligent gigabit networking is the only ultimate solution in the industry that can achieve indoor all-optical gigabit coverage.

示例性地,如图1所示,展示了FTTR全屋智能千兆组网的全部场景设备。FTTR主网关网络位置在光线路终端(Optical line terminal,OLT)与从网关之间,向上通过家庭光网连接OLT,向下提供家庭光网连接从网关。FTTR从网关与用户设备连接,向上通过家庭光网连接FTTR主网关。用户家中采用皮线+隐形光线方式重新熔接接头进行连接。For example, as shown in Figure 1, all scenario equipment of FTTR whole-house intelligent gigabit networking is displayed. The FTTR main gateway network is located between the optical line terminal (OLT) and the slave gateway. It connects the OLT upward through the home optical network and provides the home optical network connection to the slave gateway downward. The FTTR slave gateway is connected to the user equipment, and upwards is connected to the FTTR main gateway through the home optical network. The user's home uses leather wire + invisible light to re-weld the joints for connection.

现有技术中,常规的FTTR组网方式为:入户光纤接入主网关,通过分光器下联从网关。实际测试中,从网关接入损耗光衰(0-1-7.8)=-8.8dB。由于发光太强,远达不到从设备最优收光,影响宽带网络使用体验和感知,极端情况下光太强还会可能导致FTTR设备损坏。为了避免上述情况的发生,如图2所示,一般的做法是在FTTR设备01与光分路器02之间增加一个-5dB或者-15dB的光衰减器03,降低OLT的发光功率。In the existing technology, the conventional FTTR networking method is: the home optical fiber is connected to the main gateway, and the slave gateway is connected down through the optical splitter. In the actual test, the access loss from the gateway and the light attenuation (0-1-7.8)=-8.8dB. Because the light is too strong, it is far from optimal light collection from the device, affecting the broadband network experience and perception. In extreme cases, too strong light may cause damage to the FTTR device. In order to avoid the above situation, as shown in Figure 2, the general approach is to add a -5dB or -15dB optical attenuator 03 between the FTTR equipment 01 and the optical splitter 02 to reduce the luminous power of the OLT.

然而,现有的FTTR组网方式中,供应商提供的主网关至从网关发光功率为0dB/-1dB,而现有在用的从网关设备最优收光为-15dB,1:4分光器接入损耗为-7.8dB。因此,为实现最优家庭千兆光网性能,即实现最优收光,则需要在分光器外再次增加-5dB或者-15dB光衰减器,进行频繁调测最优收光,导致增加了组网成本和智家工程师施工时长。However, in the existing FTTR networking method, the luminous power from the main gateway to the slave gateway provided by the supplier is 0dB/-1dB, while the optimal light reception of the slave gateway equipment currently in use is -15dB, and the 1:4 optical splitter Access loss is -7.8dB. Therefore, in order to achieve optimal home Gigabit optical network performance, that is, to achieve optimal light collection, it is necessary to add a -5dB or -15dB optical attenuator outside the optical splitter and perform frequent debugging for optimal light collection, resulting in an increase in the number of groups. Internet cost and construction time of smart home engineers.
