OTN defines a precise layered structure for transporting and managing data: Optical Payload Unit (OPU): Holds the client signal and ensures transparent mapping. Optical Data Unit (ODU): Adds overhead for performance monitoring, multiplexing, and protection. The Optical Transport Network (OTN) is a sophisticated network architecture that leverages optical fiber transmission technology to perform essential functions such as optical signal modulation, wavelength conversion, multiplexing, amplification, protocol conversion, monitoring, redundancy backup. An optical transport network (OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. High-speed data transmission is. The Optical Transport Hierarchy (OTH) is a new transport technology for the OTN developed by the ITU. It is based on the network architecture defined in ITU G. 872 “Architecture for the Optical Transport Network (OTN)”. In short, OTNs will apply the operations, administration, maintenance, and provisioning (OAM&P) functionality of SONET/SDH to DWDM optical networks.

The transmission distance of an optical module is mainly limited by loss and dispersion. Loss occurs because the light energy dissipates due to medium absorption, scattering, and leakage during optical fiber transmission, dissipating energy at a certain rate as the transmission. Application Field: SR modules are the workhorses of data centers, facilitating high-speed connections for intra-data center communication. Among them, long-distance optical modules refer to optical modules with a transmission. After transmission through the optical fiber, the receiving interface converts the optical signals into electrical signals using a photodetector diode and outputs electrical signals of the corresponding bit rate after pre-amplification. ≥30km is long distance transmission.
