Table 1HBA single board functions and features
| Functions and Features | Description |
|---|---|
| Basic Functions |
|
| Typical Gain | HBA single board gain is 29dB. |
| Online Optical Performance Monitoring |
Provides an online monitoring optical port, from which a small amount of optical signal can be output to a spectrum analyzer or a spectrum analyzer board to monitor the spectral and optical performance of the combined wave optical signal without interrupting the service. |
| Gain Locking Technology | The EDFA within the single board has a gain locking function, which does not affect the signal gain of other channels when increasing or decreasing one or several channels or when some channels fluctuate in optical signals. |
| Transient control technology | The EDFA within the single board has a transient control function, making the system in the increase or decrease of channels, by suppressing the channel optical power fluctuations to achieve a smooth upgrade and expansion. |
| Performance Monitoring and Alarm Monitoring |
