With the advancement in the technology, the needs of the users are also growing. The demand for higher bandwidth is one of these requirements. In order to fulfill this, Fiber Optic communication is developed. It transfers the data in the form of light waves and also achieves higher data transmission rate by facilitating the wider bandwidth for transmission. This mode of communication uses various encoding schemes such as NRZ and various communication channels to improve the quality of communication.The implementation is done by using optisystem. The various encoding schemes are implemented with three different communication channels. It is observed that MDRZ outnumber rest of the encoding scheme with respect to the value of BER and Q. Factor.

“…Several research groups have researched and developed a mobile fronthaul using the intermediate frequency over fiber (IFoF) technique, which is a typical RoF technology [6], [11]- [14]. In an IFoF transmission system, multiple radio signals can be allocated, up to as many as the number of intermediate frequencies (IFs), within a particular bandwidth.…”

We demonstrate a next-generation high-capacity mobile fronthaul based on radio over fiber (RoF) technology, which links between a digital unit and a radio unit supporting two frequency assignments and 2 × 2 multiple input, multiple output antennas. To confirm the technical feasibility of a mobile fronthaul, we experimentally investigate its down-and uplink end-to-end performances including the optical and radio frequency (RF) signal path. Frequency-dependent performance deviations, error vector magnitude variations, overall system performance variations caused by optical to electrical conversion, and intermediate frequency to RF conversions are examined. Experimental verifications on multiple LTE uplink signals are performed for the first time. We also demonstrate several commercial mobile Internet services, YouTube video streaming, and file transfers using off-the-shelf mobile devices, through a mobile fronthaul based on RoF.

“…Photonic microwave or millimeter-wave generation based on optical beat notes has been studied extensively [1,2,3,4] with the development of ultra-high speed photodetectors in recent years [5,6]. These photonic generation schemes are attractive because they enable high-frequency selectivity over the entire RF region as well as high-speed phase control via electro-optic phase modulators such as traveling-wave type lithium niobate (LN) phase modulators, which are widely used in optical communication systems [7,8].…”

Optical microwave or millimeter-wave generation using the beat note of two lightwaves is an attractive technique because of its advantages of frequency-tunable micro/millimeter-wave generation, high selectivity of the operation frequency, and high-speed phase switching of the generated signals owing to the photonics-based scheme. In this paper, we propose and demonstrate the simultaneous generation of two microwave signals with a precisely-controlled phase difference using the orthogonal polarization modes existing in a polarization maintaining fiber. High stability and controllability of the phase difference between the generated two microwave signals was experimentally confirmed.
