Abstract

This application discloses a communications network and a related device. In one embodiment, the communications network includes a first optical line terminal and a second optical line terminal. The first optical line terminal is configured to send, through a first passive optical network (PON) interface based on a first PON protocol, a first optical signal to the at least one second optical line terminal. The second optical line terminal is configured to process the first optical signal and send through a second PON interface based on a second PON protocol, a processed first optical signal to at least one customer-premises equipment during downstream data transmissions, and process a second optical signal and send, through the first PON interface based on the first PON protocol, the processed second optical signal to the first optical line terminal during upstream data transmissions.

Dependent claims

A communications network, comprising a first optical line terminal, at least one second optical line terminal, and at least one customer-premises equipment;

the first optical line terminal comprises:
at least one processor;
and
a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to send, through a first passive optical network (PON) interface based on a first PON protocol, a first optical signal to the at least one second optical line terminal;
a second optical line terminal of the at least one second optical line terminal comprises:
at least one processor;
and
a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to:
denoise the first optical signal;
and
send through a second PON interface based on a second PON protocol, the denoised first optical signal to the at least one customer-premises equipment during downstream data transmissions;
and
process a second optical signal;
and
send, through the first PON interface based on the first PON protocol, the processed second optical signal to the first optical line terminal during upstream data transmissions;
and
each of the at least one customer-premises equipment comprises:
at least one processor;
and
a memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to send, through the second PON interface based on the second PON protocol, the second optical signal to the second optical line terminal connected to the at least one customer-premises equipment.

17 more elements

An optical line terminal, comprising at least one processor, a communications apparatus configured with a first passive optical network (PON) interface and a second PON interface, and a non-transitory computer-readable storage medium coupled with the at least one processor and the communications apparatus;

the non-transitory computer-readable storage medium stores programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to:
denoise a first optical signal;
and
process a second optical signal;
and
cause the communications apparatus to:
receive, through the first PON interface, a first optical signal based on a first PON protocol;
and
send the denoised first optical signal based on a second PON protocol to customer-premises equipment through the second PON interface during downstream data transmissions;
and
receive, through the second PON interface, the second optical signal based on the second PON protocol sent by the customer-premises equipment;
and
send the processed second optical signal based on the first PON protocol through the first PON interface during upstream data transmissions.

10 more elements

A method for processing optical signals in an optical line terminal, comprising:

during data downstream transmission, receiving, through a first passive optical network (PON) interface, a first optical signal in a first PON protocol;
denoising the first optical signal;
