Wavelength-Division-Multiplexing Experiment Using Dual-Wavelength Led For Short-Haul, Single-Mode Fiber Loop Transmission

We present here a WDM experiment using dual-wavelength LEDs of 1300/1500 nm with gum emitter spacing between the active facets modulated at 140/560 Mb/s over 10 km SMF. The launched power into SMF was -22.5 dBm and -19.2 dBm for the 1300 nm and 1500 nm channel respectively. Chromatic dispersion penalty for the 1500 nm channel at 560 Mb/s was about 6.5 dB and the electrical crosstalk penalty between channels was 2.5 dB. The experiment demonstrated enhanced channel capacity and the feasibility of a local subscriber loop network without employing active light source at the customer premises.
