Description
Bidirectional optical supervisory channel and timing transmission unit
Receives, processes, and transmits two optical supervisory signals.
Supports transparent transmission of two channels of FE electrical signals.
Supports IEEE 1588v2 function.
Supports physical clock function.
Supports a maximum of 37.5 dB transmission. (Not including the loss of the FIU or SFIU board).
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. In addition, the AST2 board can process the IEEE 1588v2 protocol for time synchronization. The AST2 board also supports transparent transmission of two channels of FE electrical signals and line fiber quality monitoring.
Tech Specs
| Function and Feature | Description |
| 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. |
| The AST2 board is independent of the SCC. When the SCC is not properly installed, the AST2 board can still ensure the pass-through of ECC with the two optical interfaces and monitor other stations. | |
| 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. |
| Operating wavelength | When the AST2 board works with the SFIU board, it is recommended that the working wavelength of the TM1 be 1511nm and the working wavelength of the TM2 be 1491nm. |
| When the AST2 board works with the FIU board, the supervisory channel signal wavelength is 1511 nm. | |
| Loopback | Supports outloops. |
| Optical-layer ASON | Supported |
| Line fiber quality monitoring | The line fiber quality monitoring function can be used on the NMS, and the NMS will display monitoring figures and data. The online and offline applications of line fiber quality monitoring are supported. |
| The Fiber Doctor Management System Software Fee License needs to be purchased for this function. | |
| eSFP | The board supports pluggable optical modules that use 1511 nm and 1491 nm wavelengths. |
| G.8273.2 | Supported. |
