We have constructed an optically transparent, memoryless 2:1 statistical TDM packet multiplexor for constant packet-length input. This multiplexor is the fundamental building block in a class of Cascaded Optical Delay (COD) multiplexors intended for wide-area terabit networks. The multiplexor does not require slot-aligned traffic. This multiplexor can be cascaded to build multiplexors with improved packet loss rate. In this article we present the experimental packet loss rate of the memoryless multiplexor as well as the calculated packet loss rate of larger, buffered COD multiplexors. Furthermore, we outline an optical loss compensation scheme for buffered COD multiplexors.
