“…In [12], bidirectional long reach WDM-PON system delivering 20 Gbps downstream signal and 10 Gbps upstream signal on a same wavelength using locked laser and RSOA was presented and implemented over 45 km optical fiber. In [13], for the next-generation free space optics (FSO) network, a cost-effective RSOA-based bidirectional WDM-Ro-FSO-PON was established. Over a 500 m FSO-link, 10 Gbps downstream, 1.25 Gbps upstream, and 1.49 Gbps video signals were successfully sent.…”

In this paper, we have studied and simulated bidirectional hybrid long reach Intensity Modulated and Direct Detected Optical Orthogonal Frequency Division Multiplexing Wavelength Division Multiplexing Passive Optical Network (IM/DD-OFDM-WDM-PON) with 100 Gbps of various M-Quadrature Amplitude Modulation (M-QAM) in transmitted downstream signal and 2.5 Gbps On-Off keying (OOK) upstream signal using wavelength reused technique by Reflective Semiconductor Optical Amplifier (RSOA) at Optical Network Unit (ONU). The simple, low cost and colorless long-haul IM/DD-OFDM-WDM-PON based on RSOA is designed to support extreme data rate signal by utilizing Dispersion Compensating Fiber (DCF). All results prove that IM/DD-OFDM-WDM-PON can achieve good Bit Error Rate (BER) performance over propagation length of (300 km for 4-QAM), (200 km for 16-QAM) and (50 km for 64-QAM). For comparison, the performance of the network is studied in terms of BER, the effect of the propagation length on the constellation diagram, and the relation of BER versus bit energy and noise density ratio (Eb/No).

“…As modern cities are growing bigger and bigger, digging of lands to install optical fiber cables is not feasible. Thus, Ro-FSO can be a potential carrier to deliver various high-speed digital services such as high-speed internet, video on demand, and Triple Play Services (TPS) without using optical fiber cables [12,13] as shown in Figure 1. Ro-FSO can handle the increasing mobile subscribers by transmitting RF signals through high-speed optical carrier that does not cost much or need any licensing.…”

High-speed data demand in sensitive locations has prompted new wireless technologies to grow in areas like hospitals for bio-sensor data transmission between doctors and patients. However, interference of electromagnetic spectrum or highly sensitive medical equipment in such locations can prevent radio waves which can further compromise the health of patients. Radio over Free Space Optics (Ro-FSO) can fulfil high-speed data demand in such locations without any such interference. However, the Ro-FSO performance is highly influenced by different adverse weather conditions, particularly haze and rainfall, which further cause attenuation in the transmission path of Ro-FSO systems. These atmospheric turbulences mainly affect the transmission link range of Ro-FSO systems. In this work, Ro-FSO system is designed by incorporating hybrid mode division multiplexing (MDM) and polarization division multiplexing (PDM) schemes to deliver four independent channels, each carrying 10 Gbps data upconverted to 40 GHz radio signal, over 3.4 km free space optical link operating under clear weather conditions. In addition to this, the proposed Ro-FSO link is subjected to different weather conditions, particularly partially hazy/rainy and dense fog/very rainy. The reported results indicate the achievement of acceptable bit error rate (BER≈10–3) for all channels up to 3400m FSO link under clear weather conditions, 1000m under partially haze/rain and 620 m under dense fog/heavy rain.

A novel design of optical wavelength switch, based on an asymmetric switching architecture for edge node implementation, is presented in this paper. Compared to previous research for optical core transport network applications, the proposed work has a unique aspect to build dynamic multicasting and spectral equalization, vital functionalities for optical wavelength switch in the edge of optical access networks. An optical wavelength switch was experimentally implemented and evaluated in a 4x16 switching architecture to demonstrate the concept. This dynamic multicasting and spectral equalization were achieved by utilizing liquid crystal on a silicon spatial light modulator (LCoS-SLM) device. An optimal design of computer-generated holograms (CGHs) through an improved GS algorithm was used to perform the beam steering and wavelength switching. A variety of wavelength switching scenarios has been experimentally evaluated. The measurement results showed an average insertion loss of around -12.5 dB, and the calculated crosstalks were all less than -28 dB. Its applications in digital data transmissions were evaluated to achieve a transmission speed larger than 2.5 Gbps. The eye diagram measurement results showed that most wavelength switching scenarios have nearly bit-error-free transmission. The scenario includes the multicasting with spectral equalization within the proposed asymmetrical switching architecture.
