What do you know about the Six major features of the GPON Network?

GPON Network is a new generation broadband passive optical integrated access standard based on ITU-TG.984.x standard. It is one of the hot technologies for implementing FTTX. Compared with the existing access network technology, the characteristics of GPON Network are mainly There are: high bandwidth and high transmission efficiency, QoS (Quality of Service) guarantee, better support for TDM services, complete OAM functions, simple and efficient adaptation and packaging, relatively complex technology, and high equipment cost.

Six features of GPON Network are introduced in detail:

1. High bandwidth and high transmission efficiency

With a rate of up to 2.5 Gbps, GPON Network can provide enough bandwidth to meet the growing demand for high bandwidth in future networks, while the asymmetric nature of GPON Network is better suited to the broadband data services market.

2.QoS (Quality of Service) guarantee

GPON Network can carry ATM cells and GEM frames at the same time, and has a good service level, QoS guarantee and full service access.

3. Better support for TDM business

The GPON Network can support TDM services very well. TDM refers to Time Division Multiplexing.

4. Complete OAM function

In view of the lack of network management and performance monitoring for Ethernet systems, GPON provides three OAM channels from the perspective of consumer demand and operator operation and maintenance management: embedded OAM channels, PLOAM and OMCI. They undertake different OAM tasks, forming a C/M Plane (control/management plane), and different information in the plane manages their respective OAM functions. The GPON network has rich service management and carrier-class network monitoring capabilities.

5. Simple and efficient adapter package

GPON GEM provides a flexible frame structure encapsulation, supports encapsulation of fixed length and indefinite long frames, implements common mapping for multiple services, does not require protocol conversion, and has a simple implementation process, low overhead, and high protocol encapsulation efficiency. 93%, the full use of bandwidth resources.

6. The technology is relatively complicated and the equipment cost is high

The advantages of GPON carrying multi-service with QoS guarantee and powerful OAM capability are largely at the expense of the complexity of technology and equipment, which makes the related equipment costly.
