“…Nowadays, however, high-speed systems are getting off to a big start to solve the problems of dispersions to which a coherent system is immune. Coherent systems are also able to accept chromatic dispersion from 30,000 to 80,000 ps/nm, which would mean a theoretical reaching of system over 3000 km without chromatic dispersion compensation [97][98][99][100][101]. Furthermore, it is theoretically resistant to polarization mode dispersion up to 30 ps.…”

For many years, passive optical networks (PONs) have received a considerable amount of attraction regarding their potential for providing broadband connectivity to almost every citizen, especially in remote areas where fiber optics can attract people to populate regions that have been abandoned. Error-free connectivity without dropouts can offer new opportunities to communicate, earn money and enjoy cultural events. Transmission speeds are multigigabit with distances of a few tens of kilometers; these specifications were previously reserved for high-speed and long-haul backbone networks. PONs can also support a new class of applications, such as accurate time transfer or distributed fiber sensing and follow new trends in open networking. An outline of past and current standards and standards that have been proposed for the latest generation of multigigabit PONs is provided.

“…The first implementations of DSP-based coherent optical receivers were deployed envisioning systems with 100 Gb/s per channel over single-mode fibers (SMF), and employing polarization division multiplexing (PDM) and advanced modulation formats such as m-ary phase-shift keying (M-PSK) and m-ary quadrature amplitude modulation (M-QAM) [2,8]. Such systems in combination with wavelength division multiplexing (WDM) can not satisfy future capacity demands.…”

Clock Recovery Challenges in DSP-Based Coherent Single-Mode and Multi-Mode Optical Systems

2018

We present an analysis of clock recovery algorithms in both polarization division multiplexing systems and mode division multiplexing systems. The impact of inter-polarization time skew and polarization mode dispersion in single-mode fibers, as well as the combined impact of mode mixing and mode group delay spread in multi-mode fibers under different coupling regimes are investigated. Results show that although the clock tone vanishing has a known solution for single-mode systems, in multi-mode systems even for low group delay spread, strong coupling will cause clock tone extinction, making it harder to implement an effective clock recovery scheme.

“…Coherent detection is a promising technology to realize coherent optical transmission systems beyond 100G because it can offer high spectral efficiency, improvement in optical signal noise ratio (OSNR), and large tolerance for chromatic dispersion (CD) and polarization mode dispersion (PMD) [1]. One of the essential components for the coherent detection is a coherent optical receiver consisting of a 90 o -hybrid, a balanced photodiode (BPD), and a TIA.…”

A hybrid-integrated coherent receiver module has been achieved using flip-chip bonding technology, consisting of a silica-based 90 o -hybrid planar lightwave circuit (PLC) platform, a spot-size converter integrated waveguide photodiode (SSC-WG-PD), and a dual-channel transimpedance amplifier (TIA). The receiver module shows error-free operation up to 40Gb/s and OSNR sensitivity of 11.5 dB for BER = 10 -3 at 25 Gb/s.
