GNOA overview

GNOA is a 16-port XGS-PON and GPON combo card, which can be used in the chassis of Fiberhome brand OLT AN6000-7, AN6000-15, AN6000-17, and AN6000-2.

XGS-PON is a passive optical network access technology standardized in ITU-T G.9807, which is evolved from the ITU-T G.987 (XG-PON) standard. The figure below shows the network structure of XGS-PON.

GNOA Network

Combo PON adopts the new WDM1r technology to achieve optical wave splitting, and one device can meet the bandwidth requirements from high to low of different subscribers in a unified area. The self-adaptation of GPON & XGS-PON is realized by inserting different optical modules into each PON port, which is the best choice for ISP companies under the current wave of network upgrades.


GNOA application

Advantages of XGS-PON application:
Smooth evolution: All FiberHome OLTs in the current network support XGS-PON service cards; therefore, users need not replace existing OLT equipment to provision the XGS-PON service.
High bandwidth: 10 Gbit/s in both uplink and downlink directions.
High split ratio: Provides a split ratio up to 1:256.
Compatible with XG-PON: XG-PON ONUs can coexist with XGS-PON ONUs in an ODN.
Sharing an ODN: XG-PON ONUs or XGS-PON ONUs can be connected via an existing ODN.


GNOA hight-lights

Smooth upgrade: XGS-PON service cards can replace XG-PON with little configuration change. Accordingly, services can be migrated smoothly.
Software and hardware compatibility: Bandwidth can be upgraded without replacing subracks. Various PON service cards can coexist in a subrack.
AN6000 Series Optical Line Terminal Equipment
Low power consumption: An XGS-PON card consumes less than 70 W power.
Clock and time synchronization with high precision: Uses the system time transfer protocol defined in IEEE 802.1as, and supports synchronous Ethernet (SyncE), IEEE1588 V2, and 1PPS+ToD.
Overall protection: Supports backbone fiber protection (Type B) and all-fiber protection (Type C). The switching time is no more than 50 ms.
Efficient data transmission: Encapsulates all the data to be transmitted into 125 us frames (fixed length frames) with the new XGEM encapsulation structure, which uses fewer transmission overhead bytes and improves the transmission efficiency.

Standard compliance Conforms to ITU-T G.987 and G.9807 series of standards, with good interoperability.

Throughput In the 10G/2.5G asymmetric access mode, when the XGS-PON system is fully configured with services (64 ONUs), the uplink throughput is no less than 1.9 Gbit/s, and the downlink throughput is no less than 8.5 Gbit/s.

In the 10G/10G symmetric access mode, when the XGS-PON system is fully configured with services (64 ONUs), both the uplink throughput and the downlink throughput are no less than 8.5 Gbit/s.

transmission delay The uplink average transmission delay (when the traffic is no more than 90% of the system throughput) is less than 1.5 ms (packets of all sizes are counted).
The downlink average transmission delay (when the traffic is no more than 90% of the system throughput) is less than 1 ms (packets of all sizes are counted).
