We demonstrate a bidirectional 12-channel wavelength-division-multiplexing passive optical network (WDM-PON) with 50-GHz channel spacing based on wavelength-locked Fabry–Pérot laser diodes. The maximum transmission length is 30 km including 20 km of feeder fiber and 10 km of distribution fiber. The proposed WDM-PON system can accommodate 80 channels with(More)
We demonstrate an improvement of optical receiver performance for an optical signal with beat noises. The decision threshold level is adjusted automatically according to the detected average optical power. This simple method improves optical receiver performance under a wide range of input signal conditions, e.g., beat noise level and extinction ratio. Thus(More)
We propose a new broadband light source (BLS) based on the mutual injection between two ARcoated F-P LDs. We demonstrate colorless operation of WDM-PON by using the proposed BLS and Manchester coded data. The passive optical network (PON) based on wavelength division multiplexing (WDM) has been investigated for fiber-to-the-home (FTTH). The WDM-PON is very(More)
