“…4 In the meantime, an enormous effort has been under way to incorporate EDFAs into commercial optical communication systems. After intensive laboratory research and development, Lucent Technologies (then the communication equipment division of AT&T) conducted the first field trial of a WDM optical communication system in 1989 5 and supplied the first commercial WDM system,…”

“…An early large-scale demonstration of the capability of WDM systems was the Roaring Creek Field Trial 6,7 (not shown in Figure 1), which was begun in 1989 and completed in 1991. It demonstrated transmission of four WDM channels at data rates of 1.7 Gb/s per channel over a system span of 840 km.…”

“…The first reported field experiment using FFP filters and EDFAs for a high performance multi-wavelength telecommunication system was a four-channel, 1.7 Gbit/sec/channel 70 km system with an EDFA at the transmitter and receiver end [19]. One FFP filter served as the channel selector, ASE noise filter, FSK demodulator and could have functioned as the WDM element.…”
