“…It provides the benefit of wavelength reuse in any network. By this wavelength reuse, the same wavelength can be used in any network many times provided that the same wavelength does not get overlapped on any link [17,18]. It is so because two lightpaths cannot have a similar wavelength on the same link.…”

To protect wavelength division multiplexed (WDM) networks, pre-configured protection cycles (p-cycles) found to be very speedy and efficient. To implement p-cycles in any network, we may or may not deploy wavelength converters. As the cost of wavelength converters is quite high, fully equipping the networks with wavelength converters makes it very costly. So, instead of making the network 100% wavelength convertible, we are making network convertible in some variation. We compare the spare capacity in terms of route km of fiber length and the number of wavelength converter required for the same. We ensure that making the network wavelength convertible to some extent, i.e., 50% also can perform better without much affecting spare capacity. Also, the hardware cost of converters can be reduced much with lesser use of wavelength converters.

“…The scattering related NLEs are known as Stimulated brillion scattering (SBS) [19] and stimulated Raman scattering (SRS) [20]. On the other hand, the refractive index related NLEs include four wave mixing (FWM) [21], self-phase modulation (SPM) [22] and cross phase modulation (XPM) [23]. These aforementioned types have severe effects on performance of LHOCS.…”

Palliation of Four-Wave Mixing in Optical Fibers Using Improved DSP Receiver

A long haul optical communication system (LHOCS) is one of the key resources to fulfill the higher capacity requirements in future communication networks. To launch LHOCS, the system mainly faces high order nonlinear effects. The four-wave mixing (FWM) is one of the major nonlinear effects, which limits the transmission distance. Therefore, in this paper, an advanced duo-binary (DB) modulation scheme-based system is evaluated by employing an improved digital signal processing (IDSP) approach at the receiver side to suppress the FWM effect. In addition, an analytical analysis is also performed for the proposed system. To observe the difference between the IDSP and conventional digital signal processing (DSP), the various performance metrics such as bit error rate (BER), Q-factor, and optical signal-to-noise ratio (OSNR) parameters are evaluated. Variable channel spacing along with polarization mode dispersion (PMD) are analyzed at several ranges of input powers and fiber lengths. The analytical and simulation-based calculations exhibit the effectiveness of the proposed model and hence, FWM effect are compensated to achieve 500 km optical fiber propagation range with a BER below 10−6.
