Simultaneous Generations of Independent Millimeter Wave and 10 Gbit/s Wired Signal by Single Electrode Modulator in TDM-PON Network

Abstract

We propose and present a cost effective and simple technique of simultaneous generation and propagation of millimeter wave with recently standardized 10 giga bit passive optical network (GPON) by mixing of 2.5 Gbit/s, 30 GHz radio wave with 10 Gbit/s based band signal and then modulated by single Mach Zehnder modulator (MZM). In this scheme, we have applied 1490 nm for downstream, 1310 nm for upstream transmission and ON OFF keying (OOK) modulation format to make it fully align with existing standards and infrastructure. Simulation results show error free transmission performance with negligible power penalty over 25 km bidirectional fiber. We also highlight the principles and discuss the main technical challenges for commercial realization of 60 GHz spectrum.Keywords: radio over fiber (RoF), division m (TDM), passive optical network (PON), on off keying (OOK), wave

Integration of Hybrid Passive Optical Networks (PON) with Radio over Fiber (RoF)

“…Many technologies are recommended for high-bandwidth passive optical networks to deliver required data rates for current and future services. They are 40 Gbit/s time division multiplexing (TDM) PON, wavelength division multiplexing (WDM) PON, orthogonal frequency division multiplexing (OFDM) PON, coherent ultra-dense WDM-PON (UDWDM PON), and time-wavelength division (TWDM) PON [9]. The full service access network (FSAN) group under International telecommunication union (ITU-T) has adopted the TWDM-PON for its next generation PON-2 standardization.…”

“…A hybrid TWDM-PON system that stacks four 10G-PONs onto a single fiber to deliver 40 Gbit/s integrated capacity in downstream. The ITU-T and FSAN has adopted smooth path for multi gigabit PON (GPON) evolution, based on incremental and targeted at the ultimate goal of migration to NG-PON2, cost effectively making full reuse of deployed fiber infrastructure [9]. The early installation work has already started on next generation of PON (TWDM-PON) in many countries.…”

“…In radio over fiber (RoF) systems, the radio signal modulation can be achieved by two alternate methods either to perform the baseband to RF up or down conversion at the remote BS. It will result digital transport of the information through the fiber backhaul or using optical fiber for the analog transport of wireless signals transparently [9]. On the basis of the applications, Integration of Hybrid Passive Optical Networks (PON) with Radio over Fiber (RoF) http://dx.doi.org/10.5772/intechopen.79299 the fiber feeder network can be used as active or passive optical network.…”

“…The 60 GHz band undergoes 15-30 dB/km atmospheric absorption loss based on atmospheric conditions of the area [28]. The coverage area is less than 10 m for a cell at 60 GHz that needs large number of antenna units along with high-capacity feeder network to provide wireless coverage [9]. The 60 GHz signal propagation in atmosphere is estimated by Friis transmission equation.…”
