How's the 10G GPON (XG-PON, XGS-PON) Features of Huawei EA5801 OLT

In this article, Hong Telecom will provide a brief introduction of 10G GPON and GPON. Let's have a look.

From Huawei, the 10G GPON is evolved from the existing GPON technology, the factors promoting the technology evolution to 10G GPON are as follows:
1, Developing services require higher bandwidths and the GPON technology cannot meet bandwidth requirements.
2, Innovative access technologies on the user side require higher bandwidths and the GPON technology will face bandwidth bottlenecks.
3, A greater split ratio and a longer transmission distance increase network construction investments.

The Exact Network Structure of 10G GPON:

The 10G GPON network contains an optical line terminal (OLT), optical network units (ONUs), and an optical distribution network (ODN).
* The Optical line terminal (OLT) is an aggregation device located at the central office (CO) for terminating the PON protocol.
* Optical network units (ONUs) are located on the user side, providing various types of ports for connecting to user terminals.
* The Optical distribution network (ODN) is composed of passive optical components (POS) such as optical fibers, and one or more passive optical splitters.It interconnects the OLT and ONUs.

Networking Applications of 10G GPON Network:
A 10G GPON network is of the point-to-multipoint (P2MP) type, which is the same as that of a GPON network, it is mainly applicable to the follow scenarios which as showing below:

* 01, FTTH: Fiber To The Home
* 02, FTTB: Fiber To The Building
* 03, FTTC: Fiber To The Curb
* 04, FTTM: Fiber To The Mobility Base Station
* 05, FTTO: Fiber To The Office
* 06, FTTD: Fiber To The Door

10G GPON is a passive optical transmission technology that applies in D-CCAP and FTTH solutions, Figure 4-2 shows Hybrid Networking for D-CCAP and FTTH networking applications.

Hybrid Networking for D-CCAP and FTTH, in this scenario, an OLT connects to D-CCAP users and FTTH users:

10G GPON (XG-PON and XGS-PON) is a kind of GPON Technology Evolution, you can see the GPON Technology Evolution Roadmap as below:

* XG-PON, 10-Gigabit-capable passive optical network, provides asymmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 2.488 Gbit/s ).
* XGS-PON, 10-Gigabit-capable symmetric passive optical network, provides symmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 9.953 Gbit/s ).
