Abstract
A service signal processing method includes that an optical network unit (ONU) receives a service signal; maps the service signal to a flexible optical service unit frame; and sends a first passive optical network transmission convergence frame to an optical line terminal (OLT), where the flexible optical service unit frame is encapsulated in the first passive optical network transmission convergence frame, and where the flexible optical service unit frame is used to carry the service signal in a passive optical network (PON) and an optical transport network (OTN).
Claims20
A service signal processing method implemented by an optical network unit (ONU) and comprising:
- receiving, in an optical transport network (OTN), a service signal;
- mapping the service signal to a first frame destined for a device in the OTN;
- and
- sending a second frame to an optical line terminal (OLT) in the OTN,
- wherein the first frame is encapsulated in the second frame.
A service signal processing method implemented by an optical line terminal (OLT) and comprising:
- receiving a second frame from an optical network unit (ONU), wherein the second frame comprises a first frame, and wherein the fifth first frame is comprises a first service signal;
- and
- sending a first optical transport unit (OTU) frame to a device in an optical transport network (OTN), wherein the first OTU frame carries the first frame.
An optical network unit (ONU), comprising:
- a downstream interface configured to receive a service signal in an optical transport network (OTN);
- one or more processors configured to map the service signal to a first frame destined for a device in the OTN;
- and
- an upstream interface configured to send a second frame to an optical line terminal (OLT) in the OTN, wherein the first frame is encapsulated in the second frame.
An optical line terminal (OLT), comprising:
- a first interface configured to receive a second frame from an optical network unit (ONU), wherein the second frame comprises a first frame, and wherein the first frame comprises a first service signal;
- and
- a second interface configured to send a first optical transport unit (OTU) frame to a device in an optical transport network (OTN), wherein the first OTU frame carries the first frame.
