Abstract

The embodiment of the invention provides an optical signal transmission method and a related device. An optical signal transmission method may include mapping a first optical data unit frame to a first flexible branch unit frame, the first flexible branch unit frame including a plurality of payload blocks; mapping the first flexible branch unit frame to a first optical payload unit frame, wherein a plurality of payload blocks included in the first flexible branch unit frame are distributed in a payload area of the first optical payload unit frame; mapping the first optical payload unit frame to a second optical data unit frame, the bit rate of the second optical data unit frame being greater than the bit rate of the first optical data unit frame; mapping the second optical data unit frame to a first optical transport unit frame; and transmitting the first optical transmission unit frame. According to the technical scheme of the embodiment of the invention, the bandwidth utilization rate and the adjustment flexibility of the transmission rate of the customer service are improved.

Description

technical field

[0001] The present application relates to the technical field of optical transmission, and in particular to some optical signal transmission methods and related devices. Background technique

[0002] Optical transport network (OTN), as the core technology of the next-generation transport network, can be used for flexible scheduling and management of large-capacity services, and has increasingly become the mainstream technology of the backbone transport network. Among them, at the electrical layer, OTN technology defines a powerful digital encapsulation structure, which can realize the management and monitoring of customer service signals.

[0003] Traditional solutions generally map multi-channel client service signals with fixed time slots as the mapping granularity. Practice has found that in some scenarios, the bandwidth utilization rate of the traditional solution is not high, and the adjustment flexibility of the customer service signal transmission rat...
