Abstract

Results are presented from the first installed Brazilian link in which four independent optical channels operating at 1.30 and 1.52 micron have been combined using duplex-diplex wavelength-division multiplex (WDM) configuration on a standard single-mode fiber link. The optical emitters and detectors were linked to a 24 km installed single-mode route through two MUX devices. This dual-wavelength and bidirectional scheme of transmission has been installed last year in Brasilia - Brazil, and it supports commercial traffic at 34 Mbit/s ever since. Power penalties observed in previous laboratorial experiments are discussed and compared to the results obtained from the installed dual wavelength bidirectional route.
