A.GPON manages ONUs using the extended OAM protocol

B.GPON protocol standard proposed by IEEE, EPON protocol standard proposed by ITU-T

C.Both GPON and EPON adopt single-fiber bidirectional data transmission mode, in which EPON uses 1490nm downlink wavelength to transmit data, and GPON uses 1550nm downlink wavelength to transmit data.

D.GPON provides higher downstream bandwidth
