17.1.4 Configuration Example of Automatically Transmitting Site
Information over Ethernet (Dual Homing)
An optical network unit (ONU) can automatically transmit power distribution site information
in the electrical power system through gigabit Ethernet (GE) or fast Ethernet (FE)
autonegotiation electrical ports. The ONU cooperates with an optical line terminal (OLT) to
provide GPON type C dual-homing protection, ensuring service reliability. GPON is the
acronym for gigabit-capable passive optical network.
Context
Generic object oriented substation event (GOOSE) is a mechanism defined in IEC 61850 for
rapidly transmitting events in a substation automation system. GOOSE packets are multicast
packets for communication between terminal units.
On a type C dual-homing GPON network, the two PON links between an OLT and an ONU
work in active/standby mode and they cannot forward packets at the same time. When the active
link is faulty due to a component fault, the ONU can rapidly switch services to the standby OLT.
If a protection group is bound to the status of an upstream Ethernet port or Bidirectional
Forwarding Detection (BFD) sessions on an optical line terminal (OLT), namely, a protection
group is associated with the status of an upstream Ethernet port of BFD sessions, the OLT notifies
the ONU of performing an active/standby switchover to restore services when the OLT upstream
network fails to be connected or an OLT Layer 2 physical link fails. For details about the GPON
type C protection mechanism, see

Service Requirements
l
In a smart grid, terminal units collect the running status information, as well as monitoring
and control information about the power distribution system and send the information to
the master station system.
l
The information collected by terminal units is transparently transmitted to the master station
system, and therefore the transmission network must be secure enough to ensure reliable
running of the smart grid.
l
Terminal units must communicate with each other. This is because, when a breaker is
disconnected or the switch position of an isolator switch changes, a terminal unit must
directly send the change information to the measuring and monitoring device and the
substation monitoring system in real time. GOOSE can rapidly transmit events in a
substation automation system, and requires that ONUs connecting to the same or different
PON ports support Layer 2 interconnection.
