Paper Abstract

A simple low-cost wavelength-shared WDM-PON (Wavelength-Division Multiplexing Passive Optical Network) system using star-shaped optical fiber couples, one tunable laser, AWG (Array Waveguide Gating) is proposed in this paper. In this simple architecture, a star-shaped optical fiber couple and a tunable laser are used for 32 sources to reduce the cost dramatically. Comparing with the normal OLT(Optical Line Terminal) controlling ONU(Optical Network Unit) software method, a hardware wavelength collision test method to avoid the wavelength collision for upstream channels is used in the novel system which can reduce delay time for upstream channels. Transmission tests show that the system and the method are efficient which are useful in FTTH(Fiber to Home).
