Abstract

In this work, we demonstrate an integrated optical baseband, free space optical (FSO) communication and millimeter-wave (MMW) traffics through the present passive optical network (PON) architecture by utilizing single wavelength for broadcasting triple-play services. In the execution, we exploit 10 Gbit/s on-off keying (OOK) modulation on 10 GHz Mach-Zehnder modulator (MZM) to produce the downstream baseband signal. And the 10 Gbit/s baseband signal also can cause FSO traffic within the forward error correction (FEC) target after 25 km fiber and 160 m free space transmissions. Moreover, we can utilize the fiber to the extension (FTTE) scheme to provide the 36.42 GHz MMW with 10 Gbit/s OOK data after 25 km fiber link and 8 km extended fiber transmission.

Highlights

Due to the emergence of various broadband multi-service gradually, such as cloud access, artificial intelligence (AI) application, IP-based traffic, 4K/8K video, on-line game and social networking, the utilization of widely bandwidth is increase in the access network [1], [2]
We propose and investigate an integrated optical baseband, free space optical (FSO) and MMW signals through the present passive optical network (PON) architecture by employing single wavelength in the central office (CO) for broadcasting triple-play traffics
The downstream wavelength would transmit through a length of single-mode fiber (SMF1) and a 1×4 optical splitter (OSP1)

Introduction

Due to the emergence of various broadband multi-service gradually, such as cloud access, artificial intelligence (AI) application, IP-based traffic, 4K/8K video, on-line game and social networking, the utilization of widely bandwidth is increase in the access network [1], [2]. We propose and investigate an integrated optical baseband, FSO and MMW signals through the present PON architecture by employing single wavelength in the central office (CO) for broadcasting triple-play traffics.
