Reviews
Multi-service access and aggregation node MA4000-PX allows to construct access networks based on GPON technology. The OLT allows an operator to construct scalable, failsafe "last mile" networks, ensuring high safety requirements in either urban or rural areas. MA4000-PX controls customer stations, traffic switching and transport network access.
A core element of the MA4000-PX is a scalable Ethernet L2+ switch (PP4X) that interacts with optical interface access modules PLC8 to connect customer devices via GPON technology.
The modules are installed in a standard 19" 9U Eurocase. The 9U case has two slots for PP4X switch circuit control modules installation and 16 slots for linear PCL8 modules (GPON). A single system can have one or two PP4X central switch control modules.
Installation of two modules improves the fault-tolerance on account of switch redundancy and improves the bandwidth capacity of the system through the distribution of data streams between modules via stacking.
The modules interact via 10Gbit/s interfaces.

    Management and switching hardware board PP4X
    The module of the central switch, PP4X, is a main platform element performing management and diagnostics of periphery modules, switching and aggregation of traffic.

    The installation of two modules improves fault-tolerance due to switch redundancy and increases the system's bandwidth capacity due to distribution of data streams between modules via stacking.

    The module interaction is realized via two 10 Gbps interfaces distributing the load and ensuring redundancy.
