Downstream Networking Protection
Protection Scheme
Description
Suggestion
xPON Type B
Two PON ports on the same OLT
back up each other. When one of the
PON ports fails, the system
automatically switches to the other
PON port. This protection scheme
provides port-level protection with
low costs. It protects services against
fiber failure at the working port.
It rovides port-level
protection and has a low
cost. The inter-board
protection mode is
recommended.
GPON Type C single
homing
Two PON ports on the same OLT,
two PON ports on an ONU, two
backbone optical fibers, two optical
splitters, and two tributary optical
fibers are configured to provide link-
level protection.
It rovides link-level
protection.
GPON Type C dual
homing
Two PON ports on different OLTs,
two PON ports on an ONU, two
backbone optical fibers, two optical
splitters, and two tributary optical
fibers are configured to implement
this protection. The difference
between this protection scheme and
the GPON Type C single homing
protection scheme is that the ONU
needs to be dual homed to two OLTs
in this protection scheme. This full-
backup protection scheme provides
the highest-level protection for links
and has the highest costs.
It provides full backup
protection, which is the
highest level of protection,
at the same time, it has the
highest cost.
This protection scheme can
be configured for only the
Ethernet QinQ private line
service. It does not support
TDM services, including
Native TDM and SAToP.
NOTE
The Type B protection scheme, Type C single homing scheme, and Type C dual homing protection scheme are
mutually exclusive. Therefore, only one of these protection schemes can be configured for an ONU.
12.3 SOHO Service Configuration (GPON)
This section describes Internet access, voice, and video service configurations for small office
and home office (SOHO) users in GPON access mode in fiber to the office (FTTO) scenarios.
12.3.1 Service Requirements and Usage Scenario
Small office and home office (SOHO) is positioned for miniature enterprises, such as shops and
markets, and home officers.
