Q: What the difference between different functional version?

A: The BPA is available in two functional version, namely, N1 and N2.The N1BPA is discontinued.


Q: What the last two number mean of SSN1BPA02?

A: The last two digital number means the BPA feature code, the relation as below:

Board Feature Code Output Optical Powe
SSN1BPA01 and SSN2BPA01 01 The output optical power of the BA module is 14 dBm.
SSN1BPA02 02 The output optical power of the BA module is 17 dBm.


Q: How could I calculate the fiber loss?

A: Take 120km transmission distance as example, the most deployed fiber are G.652, this type of fiber default is 0.275 dB/km, so 120km total loss is 120km*0.275dB/km=33dB.


Q: Can I use SSN1BPA02 if I don’t have SSN2BPA01?

A: Yes you can ,but remember N1BPA02 is 17dB Gain, N2BPA01 is 14dB Gain, to avoid burn down the board, make sure a 3dB attenuator is connected between fiber.


Q: Should I deploy BPA at transmit side or at receive side?

A: Deploy at transmit side to increase the launched optical power of the line board to 17dBm, or deploy at receive side to increase the receiver sensitivity to -37dBm.


Q: Can I return/exchange board if not compatible with my system?

A: Yes, please tell our sales team your system and main control board version, before your purchase.


Q: The board is new or refurbished?

A: Yes, it is original new, not been used.


Q: What is the lead time for SSN1BPA(17/-38,LC) board?

A: In normal condition is 5 days, better to confirm with our sales team before your purchase.
