Abstract: A method for data transfer in an optical network, including: amplitude modulating, by a central office, an optical carrier by a downstream data with a first rate to generate a downstream optical signal carrying the downstream data; sending the downstream optical signal to a user terminal; obtaining, by the user terminal, the downstream data from the downstream optical signal; amplitude modulating, by the user terminal, the downstream optical signal by an upstream data with a second rate to generate an upstream optical signal, wherein the ratio of the first rate to the second rate is greater than 1; sending the upstream optical signal to the central office; and receiving, by the central office, the upstream optical signal, and obtaining, by the central office, the upstream data from the upstream optical signal. Furthermore, the present invention discloses a system and device for data transfer in the optical network. With the invention, the complexity of the system may be effectively reduced, and the cost of the device may be lowered.

Abstract: A network comprising a first optical line terminal (OLT), and a second OLT in communication with the first OLT, at least one first-type optical network unit (ONU), and at least one second-type ONU. Included is an OLT configured to implement a method comprising forwarding a first downstream data from a first-type OLT to at least one first-type ONU, and transmitting a second downstream data to at least one second-type ONU. Also included is a method comprising adding at least one second-type ONU to a passive optical network (PON) comprising a first-type OLT and at least one first-type ONU without removing the first-type OLT from the PON.
