The OBU2 board amplifies Extend C-band optical signals and supports in-service optical performance monitoring, gain locking, transient state control, pump protection, online replacement of a pump card.
Table 1 describes the functions and features of the OBU2 board.
| Function and Feature | Description |
|---|---|
| Basic functions | OBU202: Amplifies the power of Extend C-band optical signals. It supports wavelengths within the 1528.8-1567.6 nm range. |
| Typical gain | Provides a typical gain of 17 dB. |
| In-service optical performance monitoring | 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. |
| Gain locking | The EDFA inside the board has the gain lock function. Adding or dropping one or more channels or optical signal fluctuation does not affect the signal gain of other channels. |
| Working mode | Supports Gain locking mode, Power locking mode and APC mode.
NOTE: After being powered on, a TN97OBU202 board works in APC mode and has no light output by default. To enable the TN97OBU202 board to output light, set the locked optical power and turn on the pump card laser. |
| Transient control function | The EDFA inside the board has the transient control function. When channels are added or dropped, the board can suppress the fluctuation of the optical power in the path so as to implement the smooth upgrading and expansion. NOTE: This function is supported only when a board works in gain locking mode. |
| Alarms and performance events monitoring |
|
| protection |
|
| Online replacement of a pump card | When a pump card works properly, you can replace a faulty pump card without interrupting services. |
