In this paper, a unified theory for the newly developed optical burst-mode receiver is presented. Based on this theory, an analysis of the performance of the receiver is given both theoretically and experimentally. The theoretical model agrees well with the experimental results. This theory can quantitatively explain the bit error rate (BER) performance of burst-mode receivers. Several potentia...

Fig.3 Digital coherent detection with polarization multiplexing, such as dual polarization quadrature phase-shift keying (DP-QPSK), has been attracting considerable attention for constructing 100 Gbit/s transmission systems. The optical front-end for the digital coherent receiver consists of polarization beam splitters (PBSs), optical hybrids, and four sets of balanced photodetectors (PDs). The...

We propose a method to estimate the amplitude of an unexpected power loss which, leveraging on calibration, enables real-time monitoring network link. It is based existing fiber-longitudinal profile evaluation technique. The reliability assessed experimentally. When anomaly located at 0 km from beginning span, estimation bias smaller than 0.2 dB for losses up 10 dB. 25 same observed but 5 In bo...

In this paper, the performance of optical code division multiple access (OCDMA) system is studied using differential phase shift keying (DPSK) with balanced detection (BD) and optical thresholding. For the OCDMADPSK receiver, the performance parameters (i) bit error rate (BER), (ii) receiver sensitivity and (iii) spectral efficiency for asynchronous multiple access network are evaluated and com...

An overview of the developments in optical wireless systems viewed from the traditional communications viewpoint of transmitter, channel and receiver is presented. The trends in modulation formats that match information to the optical wireless channel are considered. This is followed by the discussion of recent transmitter and receiver innovations, particularly the utilisation of diversity tran...
