“…Typical DWDM systems have channel spacing of 50 or 100 GHz, corresponding to a wavelength separation of 0.4 or 0.8 nm. Future DWDM systems may potentially have narrow channel spacing using narrow-band optical filters [11].…”

Abstract-The phase and amplitude responses of a narrowband optical filter are measured simultaneously using a microwave network analyzer. The measurement is based on an interferometric arrangement to split light into two paths and then combine them. In one of the two paths, a Mach-Zehnder modulator generates two tones without carrier and the narrowband optical filter just passes through one of the tones. The temperature and environmental variations are removed by separated phase and amplitude averaging. The amplitude and phase responses of the optical filter are measured to the resolution and accuracy of the network analyzer.

“…The spectral efficiency (or more precisely, the information spectral density, defined as the ratio of the information bit rate to the channel spacing) at 10-Gb/s is a maximum of 0.2 bit/s/Hz in commercial systems, corresponding to 10-Gb/s channels at 50-GHz spacing. Spectral efficiencies of 0.4 bit/s/Hz [1][2][3] and 0.8 bit/s/Hz [4] have been reported in laboratory experiments. 10-Gb/s line rates also offer the possibility of perchannel electronic compensation of inter-symbol interference (from PMD, dispersion, and/or nonlinearities) at the receiver, a potentially inexpensive, compact technique adaptable to different fiber lengths.…”

High-capacity Raman-amplified long-haul transmission and the impact of optical fiber properties

Recent laboratory experiments have demonstrated that distributed Raman amplification, advanced modulation formats, optimized dispersion maps, and forward error correction are key technologies for 10-Gb/s and 40-Gb/s DWDM terrestrial transmission over 2000 to 6000 km. The transmission fiber's Raman gain efficiency and dispersion properties are thus important parameters. Future high-bit-rate, high-capacity installed systems will require advanced transmission fibers to extend their reach to at least 2000 km, a distance also specified by a high-profile U.S. government optical networking project. This paper will address a number of the enabling fiber properties, including dispersion, dispersion slope, Raman gain efficiency, and polarization mode dispersion. In addition, several recent experiments will be reviewed, including demonstrations of high-spectral-efficiency terrestrial transmission at 10 Gb/s and 40 Gb/s over 4000 km and 3200 km, respectively, and 10-Gb/s transmission over 2400 km using 200-km spans.
