HUAWEI MA5680T GPON OLT Fiber Optical Line Terminal

The MA5680T provides the voice, data, and video services that feature large capacity, high rate, and high bandwidth. To be specific:

The MA5680T functions as an optical line terminal (OLT) in a GPON network to work with the optical network unit (ONU) and optical network terminal (ONT).

The MA5680T supports rich network applications, such as FTTH, FTTB, and FTTC.

The MA5680T meets the network requirements of base station transmission, IP private line interconnection, and multi-ISP wholesale.

The MA5680T supports the point-to-point (P2P) FE optical access. By cooperating with the ONT, the MA5680T provides users with the P2P FTTH access.

Large-capacity platform with Access and Aggregation Integration:

• Developed based on the iMAP hardware platform and the IAS software platform of Huawei, the MA5680T series product takes on the advanced architecture and design.

• The switching capacity of the backplane is up to 3.2 Tbit/s, and the bidirectional switching capacity of the control board is up to 480 Gbit/s.

• High density GE/10GE interfaces for cascading, up to 36*10GE or 384*GE interfaces, no need for additional investment of aggregation switches.

• Each GPBD board supports eight GPON ports, based on the 1:128 split ratio, the single subrack supports up to 8K ONTs. In 2012, Huawei will launch 16-port GPON board which can supports 16K ONTs.

• Sharing the development platform with Huawei's broadband access devices, the MA5600T series product support the Layer 2 and Layer 3 features of the broadband access devices to provide user-oriented and future-oriented functions.

• GE/GPON/NGPON coexisting on the same platform.

• Aggregation switches.

Any Access:

• Large capacity IPTV service provision, 8K multicast users and 4K multicast channels and 2k concurrent multicast channels.

• HQoS support 3-level QoS (Different ISP/ service/user) guarantees OLT wholesale.

• Traditional E1 service access, Native TDM or CESoP for traditional E1 service of enterprise and mobile base station access.

• E-LAN function for local traffic inter-connection, meet the requirements of enterprise and campus network.

• Powerful integrated GPON access capability:

• Supports high bandwidth. The downstream rate is up to 2.488 Gbit/s and the upstream rate is up to 1.244 Gbit/s.

• Supports long distance. The maximum physical transmission distance of the ONT is 60 km. The physical distance between the farthest ONT and the nearest ONT can be up to 20 km.

• Supports high split ratio. The 8-port GPON board supports 1:128 split ratio, which increases the access capacity and saves the optical fiber resources.

• Support high density. The MA5600T series provides the 8-port and 16-port GPON board to increase the system capacity

Powerful QoS capability:

• Supports priority control (based on the port, MAC address, IP address, TCP port ID, or UDP port ID), priority mapping and modification based on the ToS field and 802.1p, and DSCP differentiated services.

• Supports bandwidth control (based on the port, MAC address, IP address, TCP port ID, or UDP port ID) with a control granularity of 64 kbit/s.

• Supports three queue scheduling modes: priority queue (PQ), weighted round robin (WRR), and PQ+WRR.

• Supports HQoS, which assures the multi-service bandwidth for multiple users: The first level assures the user bandwidth, and the second level assures the bandwidth for each service of each user. This ensures that the assured bandwidth is allocated absolutely and the burst bandwidth is allocated fairly.
