“…It is important to state that Rayleigh backscattering distortion is independent of an optical modulator but is optical fiber dependent. That is, Rayleigh backscattering not only occurs due to reflective devices but arises from material imperfection of an optical fiber [16][17][18]. However, using separate dedicated optical fibers would significantly increase CAPEX and OPEX.…”

Abstract-In this paper, we experimentally demonstrate the seamless integration of full duplex system frequency division duplex (FDD) long-term evolution (LTE) technology with radio over fiber (RoF) for eNodeB (eNB) coverage extension. LTE is composed of quadrature phase-shift keying (QPSK), 16-quadrature amplitude modulation (16-QAM) and 64-QAM, modulated onto orthogonal frequency division multiplexing (OFDM) and single-carrier-frequency division multiplexing for downlink (DL) and uplink (UL) transmissions, respectively. The RoF system is composed of dedicated directly modulated lasers for DL and UL with dense wavelength division multiplexing (DWDM) for instantaneous connections and for Rayleigh backscattering and nonlinear interference mitigation. DL and UL signals have varying carrier frequencies and are categorized as broad frequency spacing (BFS), intermediate frequency spacing (IFS), and narrow frequency spacing (NFS). The adjacent channel leakage ratio (ACLR) for DL and UL with 64-QAM are similar for all frequency spacings while cross talk is observed for NFS. For the best case scenario for DL and UL transmissions we achieve error vector magnitude (EVM) values of ∼2.30%, ∼2.33%, and ∼2.39% for QPSK, 16-QAM, and 64-QAM, respectively, while for the worst case scenario with a NFS EVM is increased by 0.40% for all schemes.

“…A smaller frequency deviation could be used; however, stricter optical filtering and wavelength stability will be required. If stability and precise optical filtering can be provided, lower frequency deviation allows higher FSK bit rates [31].…”

“…Thus, the centralized light sources (CLS), which can effectively simplify the structure of an optical network unit (ONU) /optical network terminal (ONT) by keeping all light source in the optical line terminal (OLT) at the central office (CO) and reuses/re-modulates the light carrying downstream data in the ONU/ONT, becomes a promising technology and arouses great interesting [1][2][3][4][5][6][7]. Recently, various re-modulation schemes reusing downstream light for the upstream data transmission have been reported [3][4][5][6].…”

A novel passive optical network (PON) over optical code division multiple access (OCDMA) uplink based on the differential quadrature reference phase shift keying (DQPSK)/ on-off Keying (OOK) orthogonal re-modulation and time domain phase coherent OCDMA en/decoder scheme has been proposed. The bit error rate and receiver sensitivity of the system have been investigated, and the security performance and MAI (Multi Access Interference) property of the OCDMA uplink data have also been investigated. The results show that the proposed PON system is more cost-effective with less power penalty, and the capacity and security of upstream data can be greatly improved .
