Scope
Main Technical Content: 4.3 System Configuration and Functional Requirements 4.3.1 In the FTTR (Fiber to the Home) system, each residential user/unit should be equipped with an optical adapter unit that meets the following requirements: 1 The uplink should support XG(S)-PON/10G EPON and other 10G PON interface functions. 2 The downlink should support uplink 1.25Gbit/s and downlink 2.5Gbit/s optical interface functions. 3 It should have built-in or externally connected Wi-Fi and AC router functions that can be managed. 4 It should be able to monitor and display operational/fault statuses. 5 It should provide GE interfaces, Wi-Fi interfaces, and voice interfaces as needed for the project. 6 It is recommended to have a built-in power module, but an external DC power input port can also be provided, with a power consumption of no more than 30W. 4.3.2 Branch optical modules can be selected based on application scenarios, splitting ratios, input/output port performance, and configuration quantities. It is recommended to use unequal splitting ratio branch optical modules. 1 The branch optical module should provide an uplink optical cable/power or optical-electrical composite port. 2 For extending the branch optical module input port power, an external 220V AC power adapter can be used. 3 For a single branch optical module and the main branch optical module input port power, it can be supplied by the optical adapter unit. 4 The branch optical module power port output DC voltage should be 48V–57V. 4.3.3 The optical gateway should be selected based on the supported service types and functional requirements. It should meet the following requirements: 1 A single optical gateway device should be installed in living rooms, bedrooms, and study rooms within residential units. 2 When there are no defined rooms in the user unit, an optical gateway should be set up based on an area of approximately 40 square meters or according
