37.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Forward Error Correction (FEC)
FEC is a technique to control errors in packets and correct errors without transmitting the packets again.
FEC adds redundant information in the packets, so the receivers can identify and correct the errors in
the packets. This increases data quality and saves bandwidth usage of the OLT.
Authentication Process
The authentication process includes the six states below.
•
O1 Initial-state
: An ONT is in this state when it’s turned on. Two alarm messages, LOS (Loss of Signal)
and LOF (Loss of Frame) will be asserted. When downstream traffic is received, these alarm messages
will be cleared, and the ONT goes to O2 state.
•
O2 Standby-state
: When the ONT receives the Upstream_Overhead message, relevant parameters
will be configures, and the ONT goes to O3 state.
•
O3 Serial-Number-state
: The OLT requests GPON serial numbers of the ONT in this state. When the ONT
is discovered, the OLT will assign a unique ONT ID. The ONT goes to O4 state when it has an ONT ID.
•
O4 Ranging-state
: An equalization delay is measured for the ONT in this state. This synchronized the
upstream transmission of the ONTs located in different places. When the ONT received the
Ranging_Time message, it goes to O5 state.
•
O5 Operation-state
: The ONT can send upstream data and PLOAM messaged in this state.
