During the long-haul transmission of optical signals, the attenuation of the signals is high. Hence, the BA and PA are required to ensure that the optical receiver can receive normal optical signals.
Table 1 provides the functions and features of the BPA.
Function and Feature | BPA |
---|---|
Basic functions | Increases the launched optical power of the line board to 13-15 dBm or 15-17 dBm. As a result, when the G.652 optical fiber with a loss of 0.275 dB/km is used, the transmission distance can be 120 km, 130 km, or above. |
Pre-amplification function | Provides the PA module to pre-amplify the received optical signals. Increases the power of the small-volume optical signals by 22-25 dB (N1BPA) or 22-33 dB (N2BPA). |
Supporting the EDFA |
|
Performance events and alarms monitoring | Supports the reporting of the performance parameters of the laser. Reports various alarms and performance events, which facilitates the management and maintenance of the equipment. |
Software upgrade | Supports the software upgrade and expansion without interrupting services. |
Board | Feature Code | Description |
---|---|---|
SSN1BPA01 and SSN2BPA01 | 01 | The output optical power of the BA module is 14 dBm. |
SSN2BPA02 | 02 | Output optical power of the BA module: 14 dBm |
SSN1BPA02 | 02 | The output optical power of the BA module is 17 dBm. |
SSN1BPA03 | 03 | Output optical power of the BA module: 14 dBm |
The technical specifications of the BPA 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 BPA.
Parameter | Value |
---|---|
Input wavelength (nm) | BA: 1530 to 1565 PA: 1550.12 |
Input optical power (dBm) | BA: -6 to +3 PA:
|
Output optical power (dBm) | N1BPA: 14 to 14.5 or 17 to 17.5 (BA) N1BPA: -22 to +15 (PA) N2BPA: 14 to 14.5 (BA) N2BPA: -22 to +23 (PA) |
Noise figure (dB) | BA: < 6.5 PA: < 6 |
Minimum signal gain (dB) | +22 |
When you perform a loopback on the PA module of the BPA, prevent the damage caused by high input optical power to the optical module.
The safety class of the laser on the board is Class 1M. The maximum launched optical power of the optical interfaces is within the range from 10 dBm (10 mW) to 22.15 dBm (164 mW).
The mechanical specifications of the BPA are as follows:
The maximum power consumption of the N1BPA at room temperature (25°C) is 20 W.
The maximum power consumption of the N2BPA at room temperature (25°C) is 11 W.
