The paper discusses ultradense WDM transmission technologies and reports a field demonstration of over‑1000‑channel WDM. The authors generate an ultradense WDM signal with a supercontinuum multicarrier source producing over 1000 carriers spaced 6.25 GHz apart, and analyze four‑wave‑mixing effects and the resulting requirements on the WDM multiplexer and demultiplexer. The experiment demonstrates successful transmission of a 1046‑channel, 2.67‑Gb/s, 6.25‑GHz‑spaced ultradense WDM signal over 126 km of field‑installed fibers.
In this paper, ultradense wavelength-division multiplexing (WDM) transmission technologies are discussed, and a field demonstration of over-1000-channel ultradense WDM transmission is reported. The generation of an ultradense WDM signal using a supercontinuum multicarrier source that generates more than 1000 carriers and uniform precise channel spacing of 6.25 GHz is presented. The influence of four-wave-mixing generated in the transmission fiber and the requirements placed on the WDM multiplexer and demultiplexer is described. An over-1000-channel ultradense WDM transmission experiment is reported. A 1046 /spl times/ 2.67-Gbit/s 6.25-GHz-spaced ultradense WDM signal is successfully transmitted over 126 km of field-installed fibers in the test bed of JGN II.
