Ultra-dense, transparent and resilient ring-tree access network using coupler-based remote nodes and homodyne transceivers

摘要

We propose an Ultra-Dense Wavelength Division Multiplex Passive Optical Network (UD-WDM-PON) based on homodyne detection in a totally transparent ring-tree implementation. It is based on time switching phase diversity homodyne detection and local oscillator reuse for upstream transmission. 4 GHz spaced 1 Gb/s streams were correctly received in a 30 km experimental deployment serving 1024 users.
