华为MA5680T

华为MA5680T Huawei MA5680T huawei's OLT product introduction: The SmartAX MA5680T series is based on huawei's third generation unified platform development, the world's first convergent OLT. Fusion together exchange function, provide high density xPON, Ethernet P2P, 10 GE GE/interface, high precision clock special business TDM, Ethernet, can achieve smooth access to the Internet, video, and voice services, highly reliable business access services; While enhancing the reliability of the network, we will save the network construction investment and save the cost of transportation. SmartAX MA5680T series products include large capacity SmartAX MA5680T and medium capacity SmartAX MA5683T two specifications, the two specifications of the products are fully compatible with the hardware and software, then save the network for cost. In both specifications, SmartAX MA5680T of large capacity specifications can provide 16 business slots, with a medium capacity specification of SmartAX MA5683T providing six business slots. The key features A large Shared platform The MA5680T series provides a large capacity sharing platform with high speed switching capabilities. The MA5680T series is based on iMAP hardware platform and IAS software platform development of huawei technologies co., LTD., with advanced architecture and design philosophy. The back plate exchange capacity reaches 3.2 Tbit/s. The main control board has a two-way exchange capacity of up to 480Gbit/s. The GPBD single board supports 8 GPON ports, and the entire box supports 8K of ONT. The EPBD single board supports 8 EPON ports, with a maximum of 8K on the entire box, according to 1:6. MA5680T Shared with huawei technologies co., LTD broadband equipment development platform, but also accumulated a broadband equipment features, two, three layer provides the user and the function of support in the future. Strong GPON/EPON integrated access capability EPON access ability Using Ethernet as the carrier, the multi-point structure and non-source optical fiber transmission mode are adopted. At present, 1.25 Gbit/s can be supported by line, high-speed broadband, sufficient to meet the bandwidth requirement of the subscriber. The downside is that the bandwidth is Shared by different users, and the bandwidth is Shared by the TDM (Time Division Multiplex). The MA5680T series supports the Dynamic Bandwidth Allocation DBA (Dynamic Bandwidth Allocation) algorithm, which supports 64kbit/s control granularity, which dynamically allocates the ONT end-user Bandwidth based on changes in user requirements. The EPON system USES passive optical transmission technology, which USES the method of P2MP (Point to Multiple Point) to support 1:6, 4 light ratio. The maximum 20km capacity can be achieved. Distance measurement technology adopts the method of timing ranging, automatic ranging and initial ranging. GPON access ability High speed, supports the transfer rate of down 2.488 Gbit/s, up 1.244 Gbit/s. Long distance, the maximum logical distance of support for ONT is 60km, the maximum distance between the physical distance between the most recent ONT is 20km. High light ratio, 8 port GPON access single board supports 1:12 light ratio, thereby increasing capacity and saving fiber resources. High density, provide 8 port or 4 port GPON access single board, improve system capacity. Hierarchically high QoS guarantees that the h-qos function meets the SLA requirements of diverse business customers Strong QoS capabilities The MA5680T series has a strong QoS capability that provides the foundation for the development of various business management. Support priority control (based on port, MAC address, IP address and TCP, UDP port number), support according to the message ToS domain and 802.1 p for priority mapping and modify, support DSCP difference business. Support for bandwidth control (based on port, MAC address, IP address, TCP, UDP port number), and control granularity 64kbit/s. Support Priority Queue, PQ, Weighted Round Robin, WRR, or PQ + WRR. Support HQoS (Hierarchical Quality of Service), to solve the multi-user business more bandwidth guarantee: 1 complete bandwidth assurance to the customer, the second to complete for each user within each business bandwidth guarantee. The realization of the guaranteed bandwidth was passed, and the sudden bandwidth was passed fairly. Comprehensive security measures MA5680T series of communications services to meet the demand of the security, the security protocols were studied and the application of fully ensure the system security and user access security. System safety measures Support for the defense against the system's denial-of-service attack. Support for MAC address filtering. Support for defensive ICMP/IP message attack capability. Supports source address routing filtering capabilities. Support for blacklisting. User safety safeguards Support DHCP option82, Enhanced DHCP security. Supports MAC address and port bindings, supporting IP address and port binding. Supports MAC/IP spoofing attacks. Support ONU/ONT SN (Serial Number)/Password authentication. Supports triple churing encryption. GPON's downside is to use the method of encrypting broadcast over different users, supporting the 128-bit Encryption of the AES (Advanced Encryption Standard). Supports GPON Type B OLT dual attribution. For dual uplink, support Smart Link and Monitor Link. Flexible networking MA5680T series as much business access platform, can provide multiple access methods, and support for multiple network mode, different environment and the business network in order to meet user needs. The network of three networks of radio and television is used The power industry distribution network automation network application The reliability design of the telecommunications level MA5680T considers system reliability in all parts of system design, hardware design and software design, and fully guarantees the normal operation of the equipment. It has anti-thunder and anti-interference function. For loss type unit/parts, such as fan, power supply, battery, etc. Support for PON 1 + 1 protection (type B), support for the 50ms-class backbone fiber business protection reverse. Support to upgrade continuously. Support high temperature detection, guarantee system safety. Supports single-board temperature inquiry, temperature threshold setting and high temperature shutoff. The main control system and the upstream interface board adopt 1 + 1 redundant backup design. All business units and main control panels support the hot plug. The veneer of machine frame input power soft start circuit and protection circuit is designed, and provides the current limit and short circuit protection, improve the veneer of lightning resistance and anti surge capacity.
