ONT Product Information Guide
In the normal operating state, all the transmissions can be used for monitoring the
phase of the arriving transmission. Based on the monitoring transmission phase
information, the equalization delay can be updated.
3.14 ONT optical budget
This section provides the optical budget for all of the ONTs. Observe the safety
requirements with ONTs, which are Class 1 laser products. Figure 3-5 shows the
Class 1 laser product warning label attached to the ONT.

Warning — Operating equipment outside of its tested and
documented performance characteristics and causing an optical
overload may cause damage to equipment components, such as APD
receivers.
This can affect service delivery, and void any component or system
warranties.
