“…Intel's heterogeneous SiPh platform has enabled rapid development and high-volume manufacturing ramps for several generations of PICs for pluggable Ethernet transceivers, delivering an eightfold increase of throughput from 100Gb/s to 800Gb/s in the last years [7][8][9] . SiPh PICs for this application include heterogeneously integrated laser arrays, high speed Mach-Zehnder modulators, monitor photodiodes, passive wavelength multiplexers, and spot size converters.…”

“…OFDM, a multicarrier modulation approach, is broadly used in wireless and optical communication systems due to its high bandwidth capability and its ability to counter both inter-carrier interference (ICI) and inter-symbol interference (ISI) using a cyclic prefix (CP) [5]. OFDM, when utilized with high-order QAM, enhances the system's efficiency, permitting a high throughput with low errors.…”

“…However, CPRI demands an extremely high bandwidth, especially for MIMO applications due to the digitization process [4], raising serious concerns regarding the spectral efficiency of the digital optical fronthaul. Furthermore, enhanced CPRI (e-CPRI)-although it requires more complex RRHs-has widely mitigated the situation by fostering higher-layer functional splits, relaxing the inappeasable throughput provision of the transport network [5]. As a consequence, analog radio-over-fiber (A-RoF) provides a solution which exploits the bandwidth utilization efficiency while providing high-capacity and flexible fronthauling.…”

In this article, we simulate a converged 5G mm-wave analogue radio-over-fiber (A-RoF) system at 60 GHz, and perform offline signal processing to equalize the dispersive optical link with the three most frequently employed algorithms, i.e., the simple least mean square (LMS) algorithm, the constant modulus algorithm (CMA) and the adaptive median filtering (AMF), which are implemented in Matlab. The performances of the different algorithms are compared for various optical fiber lengths with respect to the EVM values obtained before and after equalization. In the case of QPSK in OFDM subcarriers, it is observed that the CMA algorithm performs better than the LMS and MF algorithms, with 2% and 1.4% EVM improvement respectively, while for 16QAM in OFDM subcarriers it is observed that the LMS algorithm has a very small improvement of 0.2% EVM compared to the MF algorithm, while CMA is not suitable for 16QAM modulation in the proposed converged 5G mm-wave A-RoF system at 60 GHz.

“…For GPON application, the fabrication of optical transceivers is not so challenging that both hybrid integration of active devices [2] and InP PIC [3] cannot enhance the competitiveness of PON transceivers. Currently, optical integration technologies are mature enough for commercial use [5]. We believe it will deliver significant performance and cost benefits to the optical transceivers for both 10G PON and next generation PON.…”

In this work, a prototype of 10G Combo-PON OLT transceiver based on photonic integrated circuits (PIC) is proposed and demonstrated. Key optical components for Combo-PON OLT transceiver, including high-power DFB laser, microring modulator and WDM, have been developed and validated. The Combo-PON OLT transceiver integrated four XGS-PON/GPON ports and all ports comply with I-TUT G.984.2 Class C+ standard. The advantages and disadvantages of PIC in PON application are analyzed. The analysis shows that PIC can also provide a cost and power-efficient way to implement the next generation PON transceiver for high density PON ports.
