HUAWEI 02311BWB ST2 TN13ST2 DWDM OSN 8800 OSN 6800
Product Description:
The ST2 board is mainly used to process and regenerate optical supervisory signals. In addition, the ST2 board supports the IEEE 1588v2 function. In addition, the TN12ST2 board supports line fiber quality monitoring.
For detailed functions and features, refer to Table 1.
| 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 1588v2 function. Supports physical clock function. Supports a maximum of 40.5 dB transmission.(Not including the loss of the FIU or SFIU board) NOTE: When the ST2 board is used with the STG board in an OptiX OSN 8800 universal platform subrack, the board can process physical clock signals and IEEE 1588v2. |
| 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 ST2 board is independent of the SCC. When the SCC is not properly installed, the ST2 board can still ensure the pass-through of ECC with the two optical interfaces and monitor other stations. |
| Regeneration function | The ST2 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 ST2 board works with the SFIU board, the signal wavelengths of supervisory channel for TM1 optical port is 1511 nm, and the signal wavelengths of supervisory channel for TM2 optical port is 1491 nm. When the ST2 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. For details, see the Fiber Doctor System in the Feature Description. The Fiber Doctor Management System Software Fee License needs to be purchased for this function. NOTE: Only the TN12ST2 board supports line fiber quality monitoring. |
| Overhead processing and transmission | The overhead can be processed and transmitted between the OLSP/OLSPA/OLSPB board and the TN12ST2/TN13ST2 board. |
| eSFP | The board supports pluggable optical modules that use 1511 nm and 1491 nm wavelengths. |
| G.8275.1 | Supported. For details, see the Synchronization in the Feature Description. NOTE: Only supported by the TN13ST2 board. |
| G.8273.2 | Supported. For details, see the Synchronization in the Feature Description. |
