TNF1AST401 Is Huawei Optix OSN 1800 Optical Supervisory Channel Board
Huawei Optix OSN 1800 Optical Supervisory Channel Board TNF1AST4 03031YLY Overview
TNF1AST401: Four-directional optical supervisory channel and timing transmission unit, with Advanced OTDR
As a type of optical supervisory channel unit, the AST4 board processes two channels of supervisory signals in opposite directions. In addition, the AST4 board can process the IEEE 1588v2 protocol for time synchronization. The AST4 board also supports transparent transmission of two channels of FE electrical signals and line fiber quality monitoring.
When the AST4 board works with the DFIU03/DFIU04/BAS1 board, the supervisory channel signal wavelength is 1511 nm.
The AST4 board consists of the transmit optical module, service processing module, IEEE 1588v2 module, receive optical module, control and communication module, and power supply module.
