Abstract-Interferometric crosstalk has been identified as the cause of performance limits in future transparent all-optical networks. A large number of studies have been conducted on this phenomenon using a vast array of evaluation techniques. However, most major studies have considered that although the interfering terms may differ in number, the power contribution that they all make will be identical for all interfering terms. Although this situation is easy to analyze, it does not necessarily represent the situation that is likely to occur in a real network, which will be constructed of nodes with different degrees of connectivity, quite possibly from different vendors, and therefore with differing crosstalk characteristics. This paper describes a study on the impact of unequally powered interfering terms using a rigorous analysis technique. To validate the use of the chosen technique, the paper begins by benchmarking a number of common evaluation techniques against empirically derived, experimentally verified noise performance formulas.

“…The HOM fiber itself must also be carefully designed and packaged to minimize distributed mode conversion during propagation within the HOM fiber itself. It has been reported that MPI values of less than 40 dB are required for ultra-longhaul transmission with cascaded HOM devices [56,57]. The accurate measurement of such low MPI values requires specialized techniques [58].…”

Chromatic dispersion compensation is an integral part of WDM transmission system design. Compensator properties such as insertion loss, dispersion slope and effective mode area have a large impact on WDM system performance due to nonlinear optical propagation effects. Dispersion compensator imperfections, such as multi-path interference, group delay ripple, insertion loss ripple and limited per-channel compensation bandwidth, place additional limitations on the achievable transmission distance and capacity. In this paper, a survey of key WDM transmission system experiments is undertaken to 1) review the development of chromatic dispersion compensation technologies, 2) discuss the device characteristics that most impact system design for each technology, and 3) hopefully enable the reader to better evaluate compensator technologies for specific applications.

“…Typically, is around [22], and is required for less than 1-dB power penalty at a BER of , a pin-type photoreceiver, and non return-to-zero (NRZ) modulation [22]- [26]. If the interferers are due to a single discrete reflection (e.g., a connector) rather than due to multiple reflections (e.g., Rayleigh backscatter), the tolerable SIR can be somewhat lower [24]. Allowing for a transmitter power divergence of 5 dB, (2) predicts a maximum tolerable span loss of 2 dB, which translates into a transmission distance of some 10 km at 1550 nm.…”

“…13(a), the 1-dB penalty is pushed from 26 to 19 dB when going from to , which in the above example increases the tolerable span attenuation to 8 dB (or 40 km at 1550 nm). Since the data extinction ratio has a strong impact on the beat-noise induced penalties caused by in-band crosstalk [24], the poor extinction of the 2.5-Gb/s rated DML operated at 10 Gb/s [ Fig. 13(b)] artificially reduces the allowable SIR, and is not too representative of realistically deployable 10-Gb/s systems.…”

Abstract-We discuss options for upgrading coarse wavelength-division multiplexed (CWDM) optical access links over standard single-mode fiber (SSMF) by increasing per-channel data rates from 2.5 to 10 Gb/s. We identify electronic equalization and forward error correction (FEC) as the enabling technologies to overcome the dispersion limit of SSMF. In addition, we show how FEC enhances the tolerance to in-band crosstalk, and paves the way toward fully bidirectional CWDM transmission. Due to the lack of CWDM sources rated for 10-Gb/s operation, we demonstrate full-spectrum (1310 to 1610 nm) 10-Gb/s CWDM transmission over standard-dispersion fiber using uncooled, directly modulated lasers specified for 2.5 Gb/s. All 16 CWDM channels could be transmitted over more than 40 km, yielding a capacity-times-distance product of 6.4 Tb/s/km. The longest transmission distance (80 km) was achieved at 1610 nm, equivalent to 1600 ps/nm of chromatic dispersion.Index Terms-Crosstalk, dispersion, equalizer, forward error correction (FEC), wavelength-division multiplexing (WDM).
