HUAWEI 03037356 SSN1BA2 optical power amplifier board for osn1500B osn3500 osn7500
Functions and Features:
During the long-haul transmission of optical signals, the attenuation of the signals is high. Hence, the BA is required to ensure that the optical receiver can receive normal optical signals.
The BA2 amplifies the power of two-channel optical signals. Table 1 provides the functions and features of the BA2.
Table 1 Functions and features of the BA2
| Function and Feature | BA2 |
| Basic functions | Increases the launched optical power of the line board to 13-15 dBm or 15-18 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. |
| Supporting the EDFA | Supports the automatic control of the laser temperature and optical power of the EDFA module. Supports the automatic monitoring of the input and output optical power of the EDFA module and query of the optical power of the EDFA module. Supports the protection function of the EDFA module. When no optical signals are received, the laser is automatically turned off. When optical signals are received, the laser is automatically turned on. |
| 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. |
NOTICE:
The wavelength of the optical signal transmitted to the BA2 must be within the range from 1530 nm to 1565 nm. Otherwise, the input optical signal cannot be amplified correctly. Hence, make sure that the output wavelength of the line board that is interconnected with the BA2 is within the required range.
NOTE:
The BA2 provides the intelligent power adjustment (IPA) function. When the IPA function is enabled and no input signals are detected on the receive side of a line board, the pumping laser is turned off to prevent high laser power from damaging the eyes.
