“…OCDR can expand the transmission distance by synchronizing, and reshaping the data along the optical fiber. Consequently the presence of the OCDR achieve small Bit Error Rate (BER) at the receiver end [1] [2]. Several methods are used to implement the OCDR such as: quantum dash lasers [3], self-pulsating lasers [4] and passive filtering techniques [5] [6].…”

All-Optical Clock and Data Recovery (OCDR) is considered the most promising technique to increase the optical networks distance and the data rate by synchronizing and regenerating the data along the fiber cable, consequently achieving small Bit Error Rate (BER) at the receiver end. In this paper, we design and implement the OCDR using two different techniques, Self-Pulsating (SP) using Distributed Bragg Reflector laser (DBRL) and Filtering based using Fiber Brag Grating (FBG). A comparative study and measurement of the network performance for the two methods have been presented. The experimental results show clearly the increase either transmission distance or the bitrate.

“…In the 2000s, the gigabit-capable PON (GPON) using the ITU-T G.984 standards began supporting 2.5-Gbit/s downstream and 1.25-Gbit/s upstream bandwidths with relatively strict specifications for high bandwidth efficiency. ITU-T G.984.6 was specified to increase the overall fiber length and the splitting ratio of the legacy G-PON in 2008 [6], and an active extension node in the middle of the optical network has been studied in several ways to implement an optical reach extender, such as in [7]. Both GPONs and EPONs are now being widely deployed across the globe.…”

In this work, we study the physical layer solutions for 10‐gigabit‐capable passive optical networks (PONs), particularly for an optical link terminal (OLT) including a 10‐Gbit/s electroabsorption modulated laser (EML) and a 2.5‐Gbit/s burst mode receiver (BM‐Rx) in a novel bidirectional optical subassembly (BOSA). As unique features, a bidirectional mini‐flat package and a 9‐pin TO package are developed for a 10‐gigabit‐capable PON OLT BOSA composed of a 1,577‐nm EML and a 1,270‐nm avalanche photodiode BM‐Rx, including a single‐chip burst mode integrated circuit that is integrated with a transimpedance and limiting amplifier. In the developed prototype, the 10‐Gbit/s transmitter and 2.5‐Gbit/s receiver characteristics are evaluated and compared with the physical media dependent (PMD) specifications in ITU‐T G.987.2 for XG‐PON1. By conducting the 10‐Gbit/s downstream and 2.5‐Gbit/s upstream transmission experiments, we verify that the developed 10‐gigabit‐capable PON PMD prototype can operate for extended network coverage of up to a 40‐km fiber reach.
