The specific functions of Huawei GPHF board are as follows:
Access function
GPON access: Provides 16 GPON SFP interfaces, supports transmission rates of 2.488Gbit/s downstream and 1.244Gbit/s upstream, and can meet the high-speed data access needs of a large number of users.
Support for multiple optical modules: Supports Class B+/C+/C++ single-fiber bidirectional optical modules. Optical modules of different levels are suitable for different transmission distances and optical power budget requirements. For example, the optical power budget of CLASS B+ optical module is 28.5dB, CLASS C+ is 32dB, and CLASS C++ is 35dB, which can achieve an access distance of up to 60km. Among them, CLASS C++ optical module can meet the needs of long-distance transmission.
Service carrying and management function
Multi-service converged access: OLT can realize multiple service access such as xPON, P2P GE and 10GE through this board, and supports FTTx and D-CCAP It supports multiple network construction modes, such as VLAN, data service, IPTV service, etc., to achieve full-service converged access for home users, enterprise users, and mobile bearer, meeting the needs of different user groups and service types.
VLAN support: VLANs can be divided according to different service needs, such as data services, IPTV services, etc., to achieve service isolation and traffic management, and ensure the service quality of different services.
Network planning and optimization function
Large splitting ratio support: Supports a splitting ratio of 1:128, which can effectively save optical fiber resources, improve network coverage and access capacity, and is suitable for large-scale user access scenarios such as FTTH.
Long-distance transmission: The distance difference between two ONUs to the PON port under the same PON port can reach 40km, which can better adapt to different user distribution scenarios, simplify network planning, and reduce network construction costs.
Network management and maintenance function
Intelligent management channel: It has 4-level HQoS function to improve user experience; it supports 9216 jumbo frames, greatly improves transmission efficiency, and meets the needs of large-volume data transmission.
Real-time monitoring and fault handling: Supports RSSI Detection and optical module light control can monitor optical signal strength and other parameters in real time; support rogue ONU detection and isolation to ensure stable business operation; support 1:64 eOTDR, accurate fault division and fast fault location, easy to find and solve network faults in time.
Equipment protection function: support upstream and downstream FEC, which can effectively reduce the bit error rate and improve transmission reliability; support Type B/Type C protection, when some links or equipment fail, it can realize fast switching and protection of services to ensure network continuity.
Temperature management: support temperature query and high temperature alarm, support automatic shutdown protection when the temperature is too high, ensure that the equipment works within a stable temperature range and extend the service life of the equipment.
