MA5608T Huawei SmartAX GPON OLT
The MA5600T/MA5603T/MA5608T, functioning as an integrated optical-copper access equipment, provides the integrated broadband and narrowband access and FTTx optical access services that feature high rate, high bandwidth, and high quality. It can function as an OLT, MSAN, or IP DSLAM. The MA5600T is a large-capacity device, the MA5603T is a medium-capacity device and the MA5608T is a small-capacity device.
Supports the 10G GPON and GPON access service. All the three can function as an optical line terminal (OLT) in the GPON system, working with the optical network terminal (ONT) or other optical network units (ONUs).
Supports the point-to-point (P2P) FE/GE optical access and provides users with the P2P FTTH access by cooperating with the ONT.
Provides the voice service solution based on the Session Initiation Protocol (SIP) and H.248, supports the POTS port to implement the voice service, fax service, narrowband modem service, and various supplementary services.
Provides the E1/N*64k private line service through the TDM SHDSL board. And H802EDTB board supports the TDM SHDSL feature.
Supports broadband access services such as ADSL2+, VDSL2, and SHDSL, enhancing the xDSL function.

MA5608T Particular Positioning
The MA5608T has a strong adaptability to the environment and can be deployed quickly. In FTTx networks, the OLT is moved closer to the user side, which can save backbone optical cable resources. This solves the problem of a few users, when FTTx services are applied in an area with a low population density.
Deployed at the remote end, including the base stations (BSs) and outdoor environments
2 U high, and supports a maximum of two service boards
Connected to ONUs or ONTs and used in FTTB/C and FTTH scenarios
Connected to xDSL terminals and phones and used in the MSAN/DSLAM scenari
The MA5600T/MA5603T/MA5608T supports 10G GPON access, GPON access and P2P access, which effectively meets requirements of various FTTx access applications.
Supports a split ratio of 1:128.
Support small form-factor pluggable (SFP) optical module of Class B+ or Class C+ and XFP optical module, which can be used in different scenarios.
High-density 48 single-fiber bi-directional or 24 two-fiber bi-directional GE/FE P2P optical access is supported.
Supports the high-performance and large-capacity control board SCUH. In active/standby mode, SCUH supports 20 Gbit/s switching bandwidth for each slot. In load sharing mode, SCUH supports 40 Gbit/s switching bandwidth for each slot. And provides 960G switching capacity (doubles performance capacity), improving access user bandwidth.
The MA5600T/MA5603T/MA5608T supports multiple xDSL access and POTS access modes and makes full use of existing copper cable resources to provide users with rich and flexible network services. The retransmission and INM functions solve the line quality deterioration problem caused by line bit errors and line noise, which ensures the line access quality.
The xDSL ports works with the ADSL terminal unit-remote end (ATU-R) or the VDSL terminal unit-remote end (VTU-R), which can provides the highest-density 64 channels of xDSL access and 48 channels of POTS access.
Far-end crosstalk (FEXT) is one of key factors affecting the performance and stability of the VDSL2 system. The MA5603T supports the vectoring feature. Vectoring uses vectors to solve FEXT of VDSL2 lines so as to improve bandwidth and performance of multi-pair VDSL2 lines. It effectively decreases crosstalk for short-distance lines (shorter than 1 km). The rate of a single VDSL line can be increased about 50%-90% within 800 m. Provides higher bandwidth and more types of services over existing VDSL2 lines after the rate for a single VDSL2 user is increased.
Full Service Access
This section describes the data, multicast, voice, and base station access services of the MA5600T/MA5603T/MA5608T and the QoS solution implemented by theMA5600T/MA5603T/MA5608T.
Supports the High-Performance Multicast Service. The device employs the multicast technology to provide IP video services, including live TV and QVoD, for carriers. By introducing the multicast technology, the network device can manage, control, and forward IP video services and thus meets carriers' requirements for provisioning IP video service.
The MA5600T/MA5603T/MA5608T has completed its interoperability test with all mainstream NGN/IMSs.Implements base station access solution by using MA5600T/MA5603T/MA5608T (OLT)+MDU. And the MA5600T/MA5603T/MA5608T supports clock synchronization in the base station access scenario. The MPLS PWE3 provides the E2E reliability and quality assurance for the service.
Connection to the NGN/IMS network through SIP or H.248, implementing the VoIP service (including the voice, fax, and modem services).
The MA5600T/MA5603T/MA5608T supports reconstruction of traditional voice devices such as the N*64K private line device and ISDN PRI PBX, implementing the ALL IP architecture.
Figure 1 Board structure
A board mainly consists of the following parts:
The PCB houses various functional chips of the board and is the most important part of the board. Through the front panel, the PCB provides indicators, buttons, and ports. For some boards, the PCB also provides a position for installing a daughter board.
Front panel, including the captive screws, ejector levers, and plate
Captive screws: secure the board in the subrack.
Ejector levers: used for inserting or removing the board.
Plate: connects the PCB and the ejector levers. The plate also provides a surface for attaching some labels (such as the bar code label and laser label).
