Abstract

In this paper, a passive optical add-drop multiplexer (OADM) is developed. The employment of optical couplers as opposed to the beam splitters normally used makes it a very viable low-cost system. The tapper also provides flexibility in the design, whereby the tappers´ coupling ratios can be easily changed. The effect of the tapper´s coupling ratios on the system is analyzed here, with the emphasis on the insertion loss. In varying the coupling ratio, higher drop and add powers can be obtained with an equal power of add, drop and other channel´s power found to be at 50-50 coupling
