“…In parallel with wireless connection, optical fiber provides an ideal pathway to deliver optical signals along with in-building decors to each corner. Single-mode fiber (SMF) has already acquired an indisputable position in transporting broadband integrated services to the curb, building, or home [4,5]. However, when the SMF is deployed toward in-building networks, installation cost and convenience are undisputed impediments that must be overcome.…”

A hybrid lightwave transmission system based on light injection/optoelectronic feedback techniques and fiber-visible laser light communication (VLLC) integration is proposed and experimentally demonstrated. To be the first one of its kind in employing light injection and optoelectronic feedback techniques in a fiber-VLLC integration lightwave transmission system, the light is successfully directly modulated with Community Access Television (CATV), 16-QAM, and 16-QAM-OFDM signals. Over a 40 km SMF and a 10 m free-space VLLC transport, good performances of carrier-to-noise ratio (CNR)/composite second-order (CSO)/composite triple-beat (CTB)/bit error rate (BER) are achieved for CATV/16-QAM/16-QAM-OFDM signals transmission. Such a hybrid lightwave transmission system would be very useful since it can provide broadband integrated services including CATV, Internet, and telecommunication services over both distribute fiber and in-building networks.

“…This trend also agrees with the Edholm's Law of Bandwidth [2], predicting that the data rates of wireline and wireless will converge eventually. This means that in the future, a unified (or convergent) optical wireline and wireless network is required for providing both fixed and mobile services to users [3]- [8]. Besides, millimeter-wave (mm-wave) frequency bands [3], [4] are considered for future wireless transmission.…”

We propose and demonstrate a convergent wireline and wireless access network using time-and-wavelength-division-multiplexed passive optical network (TWDM-PON) architecture. Bidirectional 40-km single-mode-fiber transmissions (including the 60-GHz wireless transmission) satisfying the forward error correction limit are demonstrated, with data rates of È10 Gb/s per wavelength in the downstream signal and 17.50 Gb/s per wavelength in the upstream signal. To achieve higher data rate, bit-loading orthogonal frequency-division modulation was used. We also analyze the laser-linewidth-induced performance variation to the signal generated by optical beating and the baseband signal.

“…In addition, in order to provide a more convenient and cost-effective application, service integration is particularly important. Multiple-play service systems were proposed for the convergence of Internet data, voice, video, and mobile services [1][2][3][4][5]. This can be implemented by using wavelength-division multiplexing (WDM) [1,6], radio-over-fiber (RoF) technologies [7][8][9]; and spectral-efficient coding techniques [10].…”

In this work, a scalable and continuous upgradable convergent optical access network is proposed. By using a multi-wavelength coherent comb source and a programmable waveshaper at the central office (CO), optical millimeter-wave (mm-wave) signals of different frequencies (from baseband to > 100 GHz) can be generated. Hence, it provides a scalable and continuous upgradable solution for end-user who needs 60 GHz wireless services now and > 100 GHz wireless services in the future. During the upgrade, user only needs to upgrade their optical networking unit (ONU). A programmable waveshaper is used to select the suitable optical tones with wavelength separation equals to the desired mm-wave frequency; while the CO remains intact. The centralized characteristics of the proposed system can easily add any new service and end-user. The centralized control of the wavelength makes the system more stable. Wired data rate of 17.45 Gb/s and w-band wireless data rate up to 3.36 Gb/s were demonstrated after transmission over 40 km of single-mode fiber (SMF).
