“…The increase in BER is due to the increase in attenuation and distortion as fibre length increase. Thus, it is important to know the reasonable length because each length of the fiber will give a different BER performance [5]. Fig.…”

A hybrid technique called SCM-RoF, which synergizes the two communication domains, radio and optical, is employed to transmit the RF signals from base station to RAU (Remote Antenna Units) on optical fibre link to utilize the benefits of both SCM (Sub Carrier Multiplexing) and RoF (Radio over Fibre) technology using a relatively new type of laser called VCSEL laser as optical source. The performance of the SCM-RoF system deploying VCSEL Source is studied by designing a communication system comprising a transmitter deploying VCSEL laser at 1550 nm as optical source, Mach Zender as the optical modulator, single mode optical fibre link and the receiver employing a photo detector. The performance analysis of the system is done by using four parameters viz. fibre length, number of subcarrier channels, frequency spacing between channels and position of first subcarrier frequency using three modulation formats ASK,FSK,PSK. A comparative study in terms of BER (Bit Error Rate) and Eye diagrams for the three modulation formats is presented. The maximum length of 45 km, with 125 channels having subcarrier frequencies between 2-20 GHz is obtained which are shown here graphically.

“…The total signal detected at the input to the fiber is modeled by the sum of N contributions for each branched fiber, which represents the reference signal for this PON. The occurrence of one or more fault in any of the branches is derived next and may be easier to analyze by subtracting the expected result obtained in equation [5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…Using the result of equation 5-18 to substitute the contribution of the n th network branch in equation 5-17 yields the result presented in equation [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. It is clear that this signal corresponds to the combination of a no-fault scenario with two additional terms balanced by the fault loss factor δ: one term dependent on parameter d corresponding to the location of the fault and the other term related to the length of the corresponding branch L n .…”

“…Considering now the occurrence of a new fault at a position d with intensity δ, two possible scenarios must be considered: either the fault happens in the feeder line, or in one of the branches. If the fault occurs in the feeder line, the model is described by equation 5-25, where S 0 (f ) represents the reference signal including all previously known faults described like in equation [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

“…Additionally, for fifth generation wireless applications, sub-carrier multiplexed [14,15] radio over fiber (SCM-RoF) [16] is the likely method of choice for access networks data aggregation. It enables better utilization of the infrastructure of the network combined with the broad bandwidth of the optical fiber.…”
