PON Protection
Configuration
The ZXA10 C300 uses the active/standby switchover mechanism and PON port
protection mechanism to guarantee stable operation of services. When the backbone
fiber connection between the ZXA10 C300 and ONU is broken and the services are
interrupted, the device will automatically switch the services to the standby PON port to
restore the services quickly.
The ZXA10 C300 supports the following four types of PON protection:
l
Type A
Type B is the backbone fiber redundancy protection. It backs up the backbone fiber
between the PON port and splitter.
l
Type B
Type B is the OLT-side redundancy protection. It backs up the OLT PON ports and
the backbone fiber between the PON port and splitter. The splitter OLT-side has two
input ports and two output ports. This protection mode can recover the service on the
OLT side only.
l
Type C
Type C is the OLT-side and ONU-side redundancy protection, It backs up the OLT
PON port, ONU (dual optical modules), splitter, and all the fibers. In this mode, the
fault at any point can be rectified via the active/standby switchover.
l
Type D
Type D is the OLT-side and ONU-side redundancy protection, also known as full
duplex protection. It backs up the OLT PON port, ONU (dual PON ports), splitter, and
all the fibers. In this mode, the fault at any point can be rectified via the active/standby
switchover.
