FTTH Apparatus and system for providing Fiber Access Platform for expansion and coexistence of communication bandwidth in Fiber To The Home service

摘要

The present invention discloses an apparatus, system, and method for providing an optical access platform for expansion and coexistence of 10G, NG EPON added based on the infrastructure of 1G EPON in the FTTH section. An apparatus according to the present invention includes a first port in which a unique bandwidth of an Ethernet Passive Optical Network (EPON) signal is set, and an EPON signal set through each port connected from an optical line terminal (OLT) device is communicated. Port part; A second port unit configured to communicate as an integrated signal of EPON signals having different bandwidths through a plurality of ports connected to the subscriber end terminal; Different wavelength sections are set for each bandwidth of the EPON signal from the OLT device, and an integrated signal is generated by multiplexing the EPON signals received through the respective first port units based on the Wavelength Division Multiplexing (WDM) to which the wavelength sections are applied. And a WDM unit for transmitting the integrated signal downward to the subscriber-end terminal through the second port unit. According to the present invention, the overlapped wavelengths of 1G and 10G are separated into unique wavelength sections, thereby enabling simultaneous EPON communication for different bands.
