Low-cost multimode WDM for the local area network

Summary form only given. This paper describes a compact transceiver module that achieves an aggregate data rate of 2.5 Gb/s over 500m and 4 Gb/s over 300m of 62MMF using 4 WDM wavelength channels each running at 622 Mb/s and 1 Gb/s respectively. We believe that the types of components used can be inexpensive enough for practical use in local area networks.
