Select all that apply.

• A

  WDM1r multiplexers can be deployed close to the CO or user as required.

• B

  GPON and XGS-PON have different rates but the same network architecture. Therefore, to ensure that the device supports XGS-PON, you only need to change the optical modules on an ONU.

• C

  The deployment of WDM1r multiplexers does not affect the calculation of optical link attenuation.

• D

  Because the center wavelengths of XGS-PON and GPON are different and do not overlap or conflict with each other, they can share an optical distribution network (ODN).
