Protection requirements

OBU1 single board belongs to fiber optic amplifier class single board, completing the amplification function of optical signal.
In ASON networking, TN11OBU101/TN12OBU101/TN13OBU101/TN11OBU104/TN12OBU104/TN13OBU104 cannot be used as an incoming fiber optical amplifier (OMS segment sender).
The OBU1 single board supports functions and features such as online optical performance monitoring, gain locking technology, and transient control technology.
The specific functions and features of OBU1 single board are shown in Table 1.
Table 1 OBU1 single board functions and features| Functions and Characteristics | Description |
|---|---|
| Basic Functions |
|
| Typical Gain | OBU101 gain is 20dB, OBU103 gain is 23dB, OBU104 gain is 17dB, OBU105 gain is 23dB, and the gain of OBU1P3 is 18dB. Description: The OBU1 indicator provides only the nominal gain value of the OBU1 single board. The actual gain contains noise and the value is greater than the nominal gain value. |
| Online Optical Performance Monitoring |
Provide online monitoring optical port, from which a small amount of optical signals can be output to the spectrum analyzer or spectrum analyzer board to monitor the spectral and optical performance of the combined wave optical signals without interrupting the business. |
| 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. |
| Working Modes | Supports gain lock mode and power lock mode.
|
| Transient Control Technology | The EDFA in the single board has the transient control function, which enables the system to realize smooth upgrade and expansion by suppressing the fluctuation of channel optical power when adding or reducing channels. |

OBU1 veneer boards other than TN13OBU1P3: Supported TN13OBU1P3: not supported Description:
TN11OBU1 does not support "SOM equalization" for optical layer single wave modulation. |
The single board metrics contain optical interface metrics, single board size, weight, and power consumption.
