Detection and monitoring of the online spectrum Provides an in-service monitoring port MON. This port connects to an optical spectrum analyzer or spectrum analyzer unit to monitor the spectrum and optical performance of the multiplexed signal without affecting traffic. Working Principle and Signal Flow The ITL board consists of the optical module, control and communication module, and power supply module. Then, the two channels of optical signals are output through the TO and TE optical interfaces respectively. The interleaver multiplexes the two channels of optical signals input from the RO and RE optical interfaces into one channel of optical signals.

Application As an OSC board, the AST2 board processes two channels of supervisory signals in opposite directions, transmits and extracts the overhead information about the system, processes and sends the overhead information to the SCC. The AST2 board also supports transparent transmission of two channels of FE electrical signals and line fiber quality monitoring. Functions and Features The AST2 board is mainly used to process and regenerate optical supervisory signals.
In addition, the AST2 board supports transparent transmission of two channels of FE electrical signals and line fiber quality monitoring. Function and Feature Description Basic function Receives, processes, and transmits two optical supervisory signals.
Supports transparent transmission of two channels of FE electrical signals. Supports IEEE v2 function. Supports physical clock function. Supports a maximum of Technical features The OSC has no limitation on the distance between two optical line amplifiers. The failure of an optical line amplifier does not affect the performance of the OSC. Regeneration function The AST2 board transmits signals from section to section. It also has the 3R function. In each regenerating station that has optical amplifiers, information can be correctly received and new supervisory signals are added.
Specifications T-bit Large Grooming Capacity, Unified Optical and Electrical Cross-Connections A total of 32 slots are provided for each subrack to support access, grooming, and management of services. In this manner, a maximum of 72T-bit 9 x 8T cross-connection capacity is supported. Flattened network facilitates service planning, deployment, and expansion. For 40G coherent technologies, the transmission distance is close to km. For G coherent technologies, the transmission distance reaches km in live network tests and km in lab tests. The optical-layer ASON supports automatic configuration of end-to-end wavelengths and wavelength-level service switching. For unified optical- and electrical-layer ASON, flexible direction selection of the optical layer and resource consolidation and regeneration of the electrical layer are fully used, providing networks with reliability up to
