Fast Synchronization 3R Burst-Mode Receivers for Passive Optical Networks

Abstract

Abstract-This paper gives a tutorial overview on high speed burst-mode receiver (BM-RX) requirements, specific for time division multiplexing passive optical networks (TDM-PONs), and design issues of such BM-RXs as well as their advanced design techniques. It focuses on how to design BM-RXs with short burst overhead for fast synchronization. We present design principles and circuit architectures of various types of burst-mode transimpedance amplifiers (BM-TIAs), burst-mode limiting amplifiers (BM-LAs) and burst-mode clock and data recovery (BM-CDR) circuits. The recent development of 10Gb/s BM-RXs is highlighted also including dual-rate operation for coexistence with deployed PONs and on-chip auto reset generation to eliminate external timing-critical control signals provided by a PON medium access control (MAC). Finally sub-system integration and state-of-the-art system performance for 10Gb/s PONs are reviewed. Copyright (c) 2013 IEEE. Personal use of this material is permitted.

This paper presents a tutorial overview of various BM-RX design techniques for both ITU-T and IEEE TDM-PONs, and their recent developments focusing on how to achieve fast RX synchronization and overall good performance. Section II describes the specific requirements of the BM-RXs from a system level point of view in terms of optical power budget, burst overhead (OH) composition for synchronization, and the overall BM-RX figure of merit. Section III discusses two typical RX coupling methods of alternating current (AC)-coupling and direct current (DC)-coupling. Their intrinsically associated technical issues and some solutions are introduced. Section IV presents various 2R BM-RXs design techniques in detail from a component development point of view. Focusing on 10Gb/s operation different configurations and design approaches of burst-mode transimpedance amplifiers (BM-TIAs) and burst-mode limiting amplifiers (BM-LAs) are reviewed and compared. 10Gb/s burst-mode clock-data recovery (BM-CDR) design techniques are separately described in Section V. Furthermore 10G/1Gb/s dual-rate BM-RX requirements and their implementations are presented in Section VI. Afterwards state-of-the-art 10Gb/s BM-RX prototypes and their sub-system performance are demonstrated i...

Integrated optical switch matrices for packet data networks

“…Burst mode transceiver technology will play a key enabling role in the currently conceived optical packet switch systems. The evolution from low rates to tens of Gb s −1 performance has been well documented for passive optical networks 70 . Burst-mode operation of up to 25 Gb s −1 is feasible for the reconfiguration time-scales envisaged for passive optical networks 71 , and a route towards 40 Gb s −1 links has been identified 72 .…”

An Asymmetric High Serial Rate TDM-PON With Single Carrier 25 Gb/s Upstream and 50 Gb/s Downstream

“…In parallel with the PON standardization evolution in ITU and IEEE, upstream BM-RX, the most critical PMD component of PON systems, have been recently developed up to 10 Gb/s [12] [13]. Further increase in upstream data rate becomes challenging due to limitations in the availability, cost and performance of optical components.…”

A 10G/1G Dual-rate Burst-mode Receiver for Next Generation Optical Access Networks

“…That is, the gain should be large when the power is small and small when the power is large. Receivers are generally classified into two groups: those with continuous AGC and those with step AGC [4,5]. The gain in continuous AGC varies continuously, whereas it varies discontinuously in step AGC.…”
