OLT MA4000-PX - Multiservice access/aggregation node

Multiservice access/aggregation node

Multiservice access and aggregation node MA4000-PX is designed for building a access network based on GPON technology. The system enables to build a scalable, fault-resistant "last mile" network to ensure the highest safety standards, both in rural and in urban areas. The access point manages subscriber units, switching traffic and connections to the transport network.

The central element of the MA4000-PX is the scalable Ethernet switch level L2+ PP4X, which works in cooperation with various types of interface modules.
The peripheral units include PLC8 modules for subscriber connection via optical access devices, GPON technology.

Design features
The MA-4000PX access platform has a modular architecture; the modules are installed in standard 19" form-factor 9U. The 9U chassis has two slots for PP4X switch control modules and 16 slots for PLC8, GPON optical line  terminal modules. The system can be equipped with one or two of the PP4X central switch modules. Installation of two modules enables to build highly reliable systems through redundancy switches and increase system capacity by distributing the data flow between modules by stacking. The interaction between the modules runs through 10 Gbps interface.

Uplink connections:

  • up to 8 ports 10G SFP+
  • up to 4 ports 10/100/1000 Base-T/Base-X

Up to 16 PLC8 modules
Up to 128 GPON ports
Up to 8192 ONT on one node.
Performance of bus access node: 440 Gbps
Connection of ONTs via GPON technology

PP4X Module
Central switch module - the main element of the platform, which generally manages and diagnoses peripheral modules, switching, aggregation and communication interface modules with higher level network equipment. The modules operate in the mode of load sharing and redundancy via two internal 10 Gbps interfaces.

GPON Network
Broadband subscriber access via “Fiber to the home” is the highest quality method of sending Triple Play, as it provides high data transmission rate at a long range.

The key advantage of PON technology is the absence of the active nodes that require a power supply on the section from OLT to ONT that significantly reduces expenditures for network exploitation. In addition, PON technology enables to save on cable infrastructure because of the reduced optical fiber total length, as far as one fiber is used for the group of up to 64 subscribers from the central node to splitter.

GPON system MA4000-PX produced by OPTOKON* is the best solution for network building in tenement houses and cottage settlements. It enables to connect large and small corporative clients in business centers.
