TL;DR: The recent progress of 100 Gb/s to 1 Tb/s class coherent PON technology is reviewed, and the latest trends in coherent DSP and the accompanying embedded coherent transceivers are summarized from the point of view of miniaturization.

TL;DR: In this paper, an erbium-doped fiber amplifier with automatic channel-by-channel gain and power regulation function is discussed with much emphasis on the pump power control scheme and the requirement for feedback circuitry.

TL;DR: This letter developed, for the first time, 10.3-Gb/s burst-mode 3R receiver incorporating a full automatic gain control optical receiver and 82.5-GS/s over-sampling clock and data recovery (CDR) for 10G-EPON.

TL;DR: In this paper, a real-time 100-Gb/s coherent transceiver with a simplified digital signal processing suitable for access spans, and a new automatic-gain-controlled erbium-doped fiber amplifier based preamplifier with an amplified spontaneous emission compensation function for the upstream to improve the minimum receiver sensitivity for coherent detection, especially at very low received signal power.

TL;DR: In this paper, the authors proposed a 100-Gb/s/λ-based coherent coherent wavelength division multiplexing passive optical network system with a hardware-efficient digital signal processing (DSP), which features a new adaptive equalization (AEQ) and carrier phase recovery (CPR).
