EPON ONT

10G EPON can be broadly categorized into the following three standards defined by IEEE 1904.1:

Most commercially available ONTs are manufactured in China and support only SIEPON-C. However, by flashing custom firmware onto these ONTs, it is possible to enable support for SIEPON-A.

CA8271S Devices ( Stick )

Device Default EPON Mgmt IP SIEPON-A Firm Support
Hisense LTF-7263-BH+ SIEPON-C 192.168.0.1
CIG XE-99S SIEPON-C 192.168.0.1

Tip

The following devices use the same hardware and can be switched by changing the firmware.

  • CIG XE-99S compatible.
  • Hisense LTF-7263-BH+ compatible.
    • Hisense LTF-7267-BH+
    • XGS800E

You can also flash the SIEPON-A firmware onto these devices.

GPON ONT

XG-PON / XGS-PON mainly use the following two transmission modes:

  • PPTP
  • VEIP

While many ISPs adopt VEIP, most ONTs based on the CA8271x currently do not support VEIP.

Note

Hardware dependent.

  • This stick has a unique vendor name registered in its vendor information, the vendor information needs to be rewritten when connecting it to a switch with vendor locking enabled.
  • Some switches may refuse to link up if the SFP LOS pin is High. In this case, fiber must be connected to the Stick.

CORTINA family

family CPU Applications
CA8271 MIPS R3000 This is an SoC optimized for SFU ONTs, providing the minimum PHY ports required for a bridge device, and the CPU uses the power-efficient MIPS architecture.
CA8289 AArch64 Cortex-A55
4 Cores
This SoC is optimized for HGU ONT, equipped with PHY for connecting multiple LAN devices, USB3.0, and PCIe for connecting WiFi SoC. The CPU uses high-performance ARM architecture.
RTL9615C AArch64 Cortex-A55
2 Cores
This SoC is a low-cost version customized based on the CA8289. The ARM core and memory channels are halved, and the interfaces are two XFIs and one 1G LAN. USB and PCIe are probably omitted.
CA7774 AArch64 Cortex-A53
4 Cores
This SoC is optimized for HGU routers. It has almost the same functions as the CA8289, and the CPU is Cortex-A53. It is for routers, so the PON IF is omitted.
