“…In this figure, it is shown that with 12dB ER and 0.07nm OBPF, the required OSNR to achieve a transmission distance of 1200km was around 18dB. Such narrow OBPF is achievable by using fibre Bragg grating (FBG) [15]. Note that the use of such narrow-bandwidth filter would tighten the requirement for laser wavelength stabilization and may need dynamic wavelength tracking to facilitate device aging and wavelength drift.…”

“…Maximum likelihood sequence estimation (MLSE) is a powerful technology to enhance the robustness of optical receivers against chromatic dispersion (CD) [1], polarization mode dispersion [2,3], and narrowband optical filtering [4]. Most notably, the combination of non-return-to-zero (NRZ) modulation with a 4-state MLSE receiver approximately doubles the CD tolerance [1].…”

Abstract: We experimentally demonstrate a 10.7-Gb/s NRZ-DPSK receiver with 4000-ps/nm chromatic dispersion tolerance by using phase demodulation with a half-bit delay in combination with a simple 4-state maximum likelihood sequence estimation (MLSE) equalizer.

“…EDC has the potential to be used in many areas of telecommunications. From the initial research work, and some key observations from the Optical Fiber Conference (OFC) in 2007 [1,2,3], it became apparent early on that long haul networks tend to use very sophisticated optical techniques such as optical quadrature phase shift keying (QPSK), coherent detection, and highly sophisticated MLSE coding. For this research, the best place on which to focus is the lOGb/s direct detection links usually used in the metro arena where fibre lengths are typically between 40 and 120km.…”
