A novel bidirectional transmission system is proposed and experimentally demonstrated using a four-port interleaver to enable unidirectional amplification. Following bidirectional transmission through 210 km of standard single-mode fibers, sensitivity variations of less than 0.2 dB, with a bit-error rate level of 10(-9) at 10 Gb/s, were observed between bidirectional and unidirectional transmissions.

In this paper, we present the design and implementation of a data-parallel compiling system. The system has been implemented on a DEC Alpha 3000 workstation and incorporated into a parallel programming environment called UPPER (User-interactive Parallel Programming EnviRonment). Given an HPF program, the built-in compiler system can automatically analyze the access pattern of the HPF program, enumerate the computation and communication sets, and then generate the SPMD code for execution on nCUBE/2. Moreover, the user interface is designed to help the programmer to capture some information during the compilation and execution phases, including interprocessor communication, distribution of data elements onto processors, and execution results.

A 50-GHz channel spaced dispersion-compensated interleaver pair for a metro add-drop network application was demonstrated using a recirculating loop. After five cascaded nodes (ten interleavers), a 2.5-dB sensitivity differential at bit-error-rate level around 10(-9) was observed between the compensated and uncompensated pairs within a +/- 10-GHz detuning frequency window.

We proposed and experimentally demonstrated a bidirectional transmission system by using a novel four-port inlerleaver to enable unidirectional amplification. After 210-km transmission. less than 0.2-dB sensitivity variations were observed between bidirectional and unidirectional transmissions.
