EX8A application:

Advantages of 10G EPON application:

Compatibility: 10G EPON is in the same standard system as EPON. 

Accordingly, EPON, non-symmetric 10G EPON, and symmetric 10G EPON ONUs can be connected to an OLT via the same ODN. The service model of 10G EPON is the same as that of EPON, and is compatible with the existing network management system, using a uniform OAM mechanism. 

High bandwidth: 10G EPON supports the symmetric rate mode (10 Gbit/s in both uplink and downlink directions) and the non-symmetric rate mode (1.25 Gbit/s in the uplink direction and 10 Gbit/s in the downlink direction). The transmission rates are raised by 10 times compared with that of 1G EPON, and the transmission efficiency is enhanced to 97%. 

High split ratio: Provides a split ratio up to 1:128. 

Flexible networking: Users can choose to use EPON ONUs, symmetric 10G EPON ONUs, or non-symmetric 10G EPON ONUs according to their demand for bandwidth. The system can be upgraded on demand. The network is simple and can be configured flexibly. Ultra-long-haul access with a high split ratio is supported. 

Cost-effective: The transfer cost per bit is reduced, and the cost of the upgrade is low.

EX8A hight-lights：

Smooth upgrade: 10G EPON service cards can replace EPON service cards 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. 

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.
