Abstract :
Results are presented from the first experimental Brazilian route in which two separate optical channels have been combined in both duplex and diplex transmission. The experiments were demonstrated over 18 km of standard single-mode fiber using 1.29 and 1.52 micron edge-emitting laser diodes at 34 Mbit/s. The optical emitters and detectors were linked to the SM fiber through specially designed WDM (wavelength division multiplexing) couplers. The results indicate that either duplex or diplex transmission can be implemented in any installed standard SM route up to 40 km
