Ortel recently completed a production run of 4λ WDM OC-48 laser transmitter systems in accordance with a DURIP (Defense University Research Instrumentation Program) contract. The total number of systems manufactured was in excess of 120 (or, 480+ individual laser transmitters), encompassing eight distinct wavelengths. A number of interesting design, manufacturability, and production testing issues were observed. This paper will discuss the details of Oriel's experience which has resulted in a simple, commercially available, low cost OC-48 WDM transmitter system. Finally, a forward looking analysis of new trends in the field of WDM will be presented.
