How to configure Huawei switches

What is GPON With the development of society and technology, the using way of the Internet is increasingly becoming diversified, which creates a great demand for very high bandwidth. More and more people are working at home. Someone uploads or downloads multimedia files for the high bandwidth demand. Someone plays games online for the high speeds and immediate reactivity needs and so on. Therefore, bringing optical fiber to every home is the definitive response to such demands for greater bandwidth.One way to provide fiber to the home is through GPON (Gigabit Passive Optical Network). GPON is a point-to-multipoint access mechanism. Its main characteristic is the use of passive splitters in the fiber distribution network, enabling one single feeding fiber from the provider's central office to serve multiple homes and small businesses.Characteristics

Performance

GPON supports several line rates for the upstream and downstream directions. It also supports legacy ATM and packet-based transport. It even has an efficient Ethernet transport capability, i.e. some of the Ethernet overhead is extracted during the encapsulation process. Additionally, GPON supports packet fragmentation, enabling efficient utilization of transport media. GPON provides adequate bandwidth and QoS for the residential customers and small businesses and some of the large enterprise services can also be supported. Services

GPON is planed to support efficiently legacy, current and future services. This is enabled by the GEM encapsulation method, which can be enhanced to support future technologies. In respect to scalability, GPON overcomes EPON with several line rate options and, especially, with the larger offered bandwidth. Security can be implemented with different encryption techniques, among which AES is the most advanced one. For the traffic provisioning, GPON uses 12-bit port IDs as are used for the Ethernet VLAN and ATM virtual channel identification. Video services (IPTV, CATV)

IPTV provides video service based on IP multicast. At the source end, different program sources are configured with different multicast addresses, and reach the ONU device through a series of broadcast servers.In CATV mode, analog signals of traditional TV programs are transmitted over the cables. Through electrical-to-optical conversion, video stream is converted into downstream optical waves on the OLT, and then superposed with downstream optical waves of the GPON in WDM mode (RF video - 1550nm). The superposed waves are transmitted in downstream through an optical fiber. After these waves reach the ONUs/ONUs, video signals are separated to provide video services.

Cost-efficiency

In respect of cost, GPON cannot compete with EPON, due to the tighter physical requirements of the transport components. GPON is the most complex of all the PONs bringing challenges to the maintenance. The remote maintenance follows the same standard as is used in SDH/SONET networks, already familiar to operators world-wide. Convergence

GPON has the best support of all the PONs for heterogeneous networking. The most important advantage of GPON is the GFP based adaptation layer, which is capable of supporting any service whether it is packet or circuit oriented.GPON is a fully optical architecture option and a GPON system consists of an optical line terminal (OLT) that connects several optical network terminals (ONTs) together using a passive optical distribution network (ODN). Like active Ethernet, it aggregates users in what is called the "outside plant" or OSP, which means no mess of fibers in a central office somewhere; like point-to-point, it avoids the need for active electronics in the field by employing a passive OSP device (the optical splitter). Being a passive device, the GPON splitter requires no cooling or powering and is therefore extremely stable; in fact, it virtually never fails.Huawei OLTs

SmartAX MA5600T Series Product

As the first aggregation OLT in the industry, the SmartAX MA5600T series products integrate the aggregation and switching functions, provide the high-density GPON and Ethernet P2P access, abundant GE/10GE ports, high precision clock and strong platform capacity, provide the basic voice, high-speed internet, fluent video, steady TDM and the Ethernet private line services, which can improve the network reliability, reduce the investment in network construction, and reduce the O&M costs.

The Huawei MA5600T series product mainly includes the large-capacity MA5600T and the medium-capacity Huawei MA5603T. The hardware and software of these two models are fully compatible with each other to reduce the costs of spare parts and O&M costs. The difference of MA5600T and MA5603T is that MA5600T provides 16 service slots and MA5603T provides 6 service slots.

Huawei ONTs

Optical fiber access era is coming. However, the lack of ONT is becoming the serious challenge for FTTH deployment. As one of the most important part, ONT directly affect the performance, reliability, maintainability and scalability of whole FTTH network. With rich knowledge in the fiber access field and 10 years of accumulated technology experience, Huawei launched a series of FTTH ONT.HG863The HG863 provides four GE/FE auto-adapting Ethernet ports and features high-performance forwarding capabilities to ensure excellent experience with VoIP, Internet and HD video services.HG8010Huawei HG8010 provides one POTS port and one GE/FE auto-adapting Ethernet port and features high-performance forwarding capabilities.

HG8110Huawei HG8110 provides one POTS port and one GE/FE auto-adapting Ethernet port and ensures excellent experience with VoIP, Internet and HD video services.HG8240Huawei HG8240 provides two POTS ports and four GE/FE auto-adapting Ethernet ports and ensures excellent experience with VoIP, Internet and HD video services.HG8245Huawei HG8245, a high-end home gateway, provides two POTS ports, four GE/FE auto-adapting Ethernet ports and one Wi Fi port.HG8247Huawei HG8247, a high-end home gateway, provides two POTS ports, four GE/FE auto-adapting Ethernet ports, one CATV port and one Wi Fi port.
