Patent ID: 8923697

Claim:
A long reach optical amplification device, comprising a first optical diplexer, a downlink optical amplifier, a second optical diplexer, and an uplink optical amplifier, wherein the first optical diplexer is configured to transmit one or multiple downlink optical signal(s) from a first segment of Feeder fiber, which is associated with passive optical networks, to the downlink optical amplifier, and couple one or multiple uplink optical signal(s) outputted by the uplink optical amplifier, which is associated with the passive optical networks, to the first segment of Feeder fiber; and the first optical diplexer has a universal interface connected to the first segment of Feeder fiber, an output terminal connected to the downlink optical amplifier, an input terminal connected to the uplink optical amplifier; the downlink optical amplifier is configured to amplify one or multiple downlink optical signal(s) associated with the passive optical networks, and to output the amplified downlink optical, signal(s) to the second optical diplexer; the second optical diplexer is configured to couple one or multiple downlink optical signal(s) outputted by the downlink optical amplifier, which is associated with the passive optical networks, to a second segment of Feeder fiber, and transmit one or multiple, uplink optical signal(s) from the second segment of Feeder fiber, which is associated with the passive optical networks, to the uplink optical amplifier; and the second optical diplexer has a universal interface connected to the second segment of Feeder fiber, an output terminal connected to the uplink optical amplifier, and an input terminal connected to the downlink optical amplifier; and the uplink optical amplifier is configured to amplify one or multiple uplink optical signal(s) associated with the passive optical networks, and to output the amplified uplink optical signal(s) to the first optical diplexer; wherein the first segment of Feeder fiber is a Feeder fiber connected between the device and an optical line termination (OLT); and the second segment of Feeder fiber is a Feeder fiber connected between the device and an optical splitter; wherein the device further corn rises a local management box which controls and manages the uplink optical amplifier and the downlink optical amplifier according to requirements of the optical line termination; wherein the local management box comprises a local controller and an embedded optical network termination (EONT), wherein the optical line termination manages and controls the downlink optical amplifier and the uplink optical amplifier by way of a shunt coupler and the local management box.
