The OBU1 supports the online optical performance monitoring function, gain lock, transient control, and other functions.
Table 1 provides the functions and features of the OBU1.
| Function and Feature | OBU1 |
|---|---|
| Basic functions | Amplifies a maximum of 40 channels of optical signals with the channel spacing of 100 GHz at the same time. Supports the system to transmit services over different fiber spans without electrical regeneration. |
| Typical gain | The typical gain of the OBU101 is 20 dB and the typical gain of the OBU103 is 23 dB. |
| Online optical performance monitoring function | Provides the online monitoring interface. A small amount of optical signal can be transmitted to the spectrum analyzer through the interface so that the spectrum and optical performance of the multiplexed optical signal can be monitored without a service interruption. |
| Gain lock function | The EDFA inside the board has the gain lock function. When one or more channels are added or dropped, or optical signals of certain channels fluctuate, the signal gain of other channels is not affected. |
| 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 to realize the smooth upgrading and expansion. |
| Performance events and alarms monitoring | Checks and reports the optical power. Controls the temperature of the pump laser. Detects the pump driving current, back facet current, cooling current, temperature of the pump laser, and ambient temperature of the board. |
The OBU1 is available in two types, namely, OBU101 and OBU103. The OBU101 is used at the receive end and the OBU103 is used at the transmit end.
The feature code of the OBU1 contains six characters, which indicate the gain and maximum nominal input optical power of the optical signals processed by the OBU1.
Table 1 describes the feature code of the OBU1.
| Feature Code | Indication | Description |
|---|---|---|
| The first character | - | Is always "G". |
| The second and third characters | Gain | Indicates the gain. |
| The fourth character | - | Is always "I". |
| The fifth and sixth characters | Maximum nominal input optical power | Indicates the maximum nominal input optical power. |
Consider the TN11OBU1 whose feature code is "G23I-3" as an example. "G23I-3" indicates that the gain is 23 dB and the maximum nominal input optical power is -3 dBm.
The technical specifications of the OBU1 include the parameters specified for optical interfaces, laser safety class, mechanical specifications, and power consumption.
Table 1 lists the parameters specified for the optical interfaces of the OBU1.
