“…If an eavesdropper can isolate individual user's signal, he can use a simple energy detector to detect whether energy is present or not in each bit interval. So to overcome this problem various new systems are proposed in which advanced modulation format can be used for security enhancement [11][12][13]. Figs.…”

“…The orthogonality principle in advanced modulation schemes makes it possible to transmit several kinds of data in a single channel which upturns the number of consumers and broadens the channel capacity [7,8]. The authors in [9] investigated the ASK/DPSK scheme with direct detection receivers.…”

“…This has been achieved by using two polarizations of the light to code the data . High spectral efficiency and bandwidth efficiency are the major reasons for which orthogonal modulation format and Raman‐EDFA hybrid optical amplifier has gained much attention for dense wavelength division multiplexed (DWDM) optical systems . The combined use of optimized OP, CSRZ, and DPSK along with DD can reduce nonlinear effects and enable high power transmission.…”

Summary Polarization mode dispersion (PMD) has become one of the major limiting factors for high‐bit‐rate optical transmission systems. This paper evaluates the performance of dense wavelength division multiplexed (DWDM) system with PMD at 80 Gb/s in the presence of Kerr‐nonlinear effects. Orthogonally modulated signals have been investigated and compared for tolerance against PMD in a DWDM transmission system with direct detection receivers. The optimized combinations of orthogonal polarization (OP) with carrier‐suppressed return‐to‐zero (CSRZ) and CSRZ differential‐phase‐shift‐keying signals are shown to improve PMD tolerance over high bit rates and long transmission lengths. Improved performance greater than 4 dB is observed for CSRZ modulated signal with OP because of less channel cross talk and reduced power transfer between adjacent bits over different PMD values. The numerical results demonstrate that our proposed orthogonally modulated signals perform better with lesser complex direct detection receivers. Copyright © 2015 John Wiley & Sons, Ltd.
