“…An EPC using feed-forward equalization and decision feedback equalization [10] is becoming standardized for multimode fibers [11] but can also be applied to single-mode fibers (SMFs) [12]. Another form of receiver equalization is maximum likelihood sequence estimation (MLSE).…”

Abstract-We show, using simulations, that a combination of orthogonal frequency division multiplexing (OFDM) and optical single sideband modulation can be used to compensate for chromatic dispersion in ultralong-haul wavelength-division multiplexed (WDM) systems. OFDM provides a high spectral efficiency, does not require a reverse feedback path for compensation, and has a better sensitivity than nonreturn to zero. This paper provides design rules for 800-4000-km optical-OFDM systems. The effects of WDM channel number and spacing, fiber dispersion, and input power per channel on the received Q are studied using extensive numerical simulations. These effects are summarized as a set of design rules.Index Terms-Compensation, fiber dispersion, fiber nonlinearity, four-wave mixing (FWM), long haul, optical single sideband modulation (OSSB), orthogonal frequency division multiplexing (OFDM).

“…Multiple EDC chip and transmitter module vendors (AMCC, Apogee/CyOptics, Azna/Finisar, Broadcom, Essex/Avanex and Vitesse) recently conducted interoperability testing hosted by Vitesse Systems Lab [6][7] to facilitate the deployment of new applications codes. The baseline objective for the interoperability was to achieve transverse compatibility as required by G.959.1 [5], meeting the required back-to-back (B2B) sensitivity of -24 dBm, maximum path penalty of 2 dB at reach, and minimum BER of 1E-12.…”

The current status of industrial efforts to standardize interoperable optical interfaces applied to transmitters and receivers is reviewed with particular emphasis on the application of EDC and advanced modulation schemes emerging from OIF/ITU-T targeted transmissions over longer dispersion uncompensated distances.The value proposition of EDC for metro and regional networks is two-fold: reach extension, and cost reduction. An example would be to take a link that is normally limited to 80 km and with EDC technology extend it to 120 km (assume worst-case dispersion of 20ps/nm/km) with minimal or no additional expense to the system user. This eliminates the use of bulky and costly optical dispersion compensation means such as DCF. Alternatively, EDC enhanced system performance margins could be leveraged in qualification testing, allowing associated operational savings. a1229_1.pdf NWC2.pdf OFC/NFOEC 2008 978-1-55752-855-1/08/$25.00 ©2008 IEEE

“…Multiple commercial vendors offer EDC for reaches of 2400 ps/nm in a tunable manner with adequate margins at 2.5 and 10.7 Gb/s data rates [52]. Another way to think of Q is as the difference between the means of the signal 1s and 0s divided by the sum of their standard deviations, assuming that standard deviations are gaussian in distribution.…”
