Huawei MA5680T Data File GPON OLT Brief Introduction

The SmartAX MA5680T series are developed based on Huawei's third generation unified platform and are the first aggregation OLTs in the world. The MA5680T series integrate the aggregation and switching functions, provide the high-density xPON, Ethernet P2P, and GE/10GE ports, and provide the TDM and Ethernet private line services with high clock precision to support smooth

Internet access service, video service, voice service, and high-reliability service access. This series improve the network reliability, reduce the investment in network construction, and reduce the O&M costs.

The MA5680T series include the large-capacity SmartAX MA5680T and the medium-capacity SmartAX MA5683T. The hardware and software of these two models are fully compatible with each other to reduce the costs of goods preparation for the network. In these two models, the SmartAX MA5680T provides 16 service slots and the SmartAX MA5683T provides 6 service slots.

Key Features

Large-capacity shared platform

The MA5680T series provide the large-capacity shared platform that supports a high-speed switching capacity.

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

The switching capacity of the backplane is up to 3.2 Tbit/s.

The bidirectional switching capacity of the control board is up to 480 Gbit/s.

The GPBD board supports eight GPON ports and the entire subrack supports up to 8K ONTs.

The EPBD board supports eight EPON ports. Based on the 1:64 split ratio, the entire subrack supports up to 8K ONTs.

Sharing the development platform with Huawei's broadband access devices, the MA5680T series support the Layer 2 and Layer 3 features of the broadband access devices to provide user-oriented and future-oriented functions.

Powerful integrated GPON/EPON access capability

1. EPON access capability

The point to multi-point (P2MP) architecture is used to support the passive optical transmission over Ethernet. Symmetrical upstream and downstream rates of 1.25 Gbit/s are supported to provide the high-speed broadband services, meeting the bandwidth requirements of access users.

In the downstream direction, the bandwidth is shared by different users in the encrypted broadcast mode. In the upstream direction, time division multiplex (TDM) is used to share the bandwidth.

The MA5680T series support dynamic bandwidth allocation (DBA) with the granularity of 64kbit/s. Therefore, the bandwidth of ONT terminal users can be dynamically allocated based on the user requirements.

The EPON system uses the passive optical transmission technology, and the optical splitter uses the P2MP mode and supports a split ratio of 1:64.

The supported transmission distance is up to 20 km.

The ranging technology can be scheduled ranging, automatic ranging, or initial ranging.

2. GPON access capability

High rate is supported. The downstream rate is up to 2.488 Gbit/s and the upstream rate is up to 1.244 Gbit/s.

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

High split ratio is supported. The 8-port GPON access board supports a split ratio of 1:128, which increases the capacity and saves the optical fiber resources.

High density is supported. The MA5680T series provide the 8-port or 4-port GPON access board to increase the system capacity.

The H-QoS (hierarchical quality of service) function is supported to meet the SLA requirements of various commercial customers.

Powerful QoS capability

The MA5680T series provide the following powerful QoS solutions to facilitate the management of various services:

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.

Comprehensive security assurance measures

The MA5680T series meet the security requirements of the telecommunication services, fully use the security protocols, and fully ensure the security of the system and the user.

1. System security measure

Protection against the DoS (denial of service) attack MAC (media access control) address filtering Anti-ICMP/IP packet attack Source address routing filtering Blacklist.

2. User security measure

DHCP (Dynamic Host Configuration Protocol) Option 82 to enhance the DHCP security

Binding between MAC/IP addresses and ports

Anti-MAC spoofing and anti-IP spoofing

Authentication based on the serial number (SN) and password of the ONU/ONT

Triple churning encryption

Encrypted broadcast transmission in the GPON downstream direction for different users,such as AES (advanced encryption standard) 128-bit encryption

GPON type B OLT dual homing Smart link and monitor link for the network with dual upstream channels.

Flexible network topology

As a multi-service access platform, the MA5680T series support multiple access modes and multiple network topologies to meet users' network topology requirements on different environment and services.

Smooth Evolution from GPON to 10G GPON of Huawei OLT MA5680T/MA5683T

By adding the WDM1r component, the MA5600T/MA5603T can be smoothly upgraded from GPON to 10G GPON.

Carriers can newly construct a 10G GPON network or upgrade a GPON network to a 10G GPON network, as shown in Figure 1. Specifically, the WDM1r component is added to the OLT so that GPON and 10G GPON signals can be transmitted over the same ODN in the multiplexing mode.

What’s the advantages of Huawei S6700 Series Switch Regarding Access Performance

Large-capacity, High-density 10 Gbit/s Access To provide sufficient bandwidth for users, many servers use 10G network adapters, especially servers in data centers. The Huawei S6700 Series Switch can be used in data centers to provide high forwarding performance and 10GE ports. The S6700 (Huawei S6720-32C-SI-AC) has the highest density of 10GE ports and largest switching capacity among counterpart switches. Each S6700 (Huawei S6720S-26Q-EI-24S-AC) provides a maximum of 48 line-speed 10GE ports. Ports of the S6700 support 1GE access and 10GE access and can identify optical module types, minimizing the return on investment and allowing users to deploy service flexibly. Huawei S6700 Series Switch has a large buffering capacity and uses advanced buffer scheduling mechanism to ensure non-block transmission of high traffic volume in data centers.
