“…Along with RS codes, also stronger FEC codes such as low-density parity-check codes or staircase codes have been proposed for PONs in the literature [26]- [28]. In this section, we evaluate the models for PON systems with hard-decision (HD) FEC in terms of achievable information rates (AIRs) [29].…”

“…Furthermore, it is theoretically resistant to polarization mode dispersion up to 30 ps. On the other hand, a coherent system is only the beginning, the main part of these systems is electrical and in particular digital signal processing (DSP) signal processing [102][103][104][105][106][107][108][109][110].…”

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.

“…While other alternatives such as Kramers-Kronig [4] or full coherent receivers allow for a longer reach, receiver cost and complexity have prevented their adoption in access networks up to this date. Coherent receivers featuring lower complexity have also been proposed for PON applications [5,6]. In [7], a simplified coherent receiver is reported achieving −37.6 dBm sensitivity (BER = 1 × 10 −3 ) at 10 Gbps.…”

Quasi-coherent optical receivers have recently emerged targeting access networks, offering improved sensitivity and reach over direct-detection schemes at the expense of a higher receiver bandwidth. Higher levels of system integration together with sufficiently wideband front-end blocks, and in particular high-speed linear transimpedance amplifiers (TIAs), are currently demanded to reduce cost and scale up receiver data rates. In this article, we report on the design and testing of a linear TIA enabling high-speed quasi-coherent receivers. A shunt-feedback loaded common-base topology is adopted, with gain control provided by a subsequent Gilbert cell stage. The circuit was fabricated in a commercial 130 nm SiGe BiCMOS technology and has a bandpass characteristic with a 3 dB bandwidth in the range of 5–50 GHz. A differential transimpedance gain of 68 dBΩ was measured, with 896 mVpp of maximum differential output swing at the 1 dB compression point. System experiments in a quasi-coherent receiver demonstrate an optical receiver sensitivity of −30.5 dBm (BER = 1 × 10−3) at 10 Gbps, and −26 dBm (BER = 1 × 10−3) at 25 Gbps. The proposed TIA represents an enabling component towards highly integrated quasi-coherent receivers.
