Popular data networks in the last mile are Time Division Multiplexed (TDM) point-to-multipoint (P2MP) Passive Optical Networks (PON)s networks. Wherever there is provision to deploy fiber cables, it is the most preferred transmission medium as these networks are able to meet the growing bandwidth demands. For reliable transmission and to meet the service level agreements and we need to monitor the...
Mode Division Multiplexing (MDM) over Few Mode Fiber (FMF) enhances the capacity of an optical fiber system by providing additional degrees of freedom in the form of modes which are selectively excited at the transmitter and selectively detected at the receiver. The key to capitalize on such a system is implementation of low loss mode multiplexer (mux) and de-multiplexer (de-mux) with low modal crosstalk...
The concept of Smart Cities becomes paramount importance both to Government and Private Sectors. The increasing pressure of urbanization creates tremendous pressure to civic infrastructures like drainage, water system, electrical networks (Smart Grid), transportation etc [1] -- [3]. The use of Big Data Analytics is becoming a necessary tool to design and monitor Smart Cities. With the cost of sensors...
In this paper optical code-division multiple-access (O-CDMA) packet network is considered, which offers inherent security in the access networks. The application of O-CDMA to multimedia transmission (voice, data, and video) is investigated. The simultaneous transmission of various services is achieved by assigning to each user unique multiple code signatures. Thus, by applying a parallel mapping technique,...
In this paper optical code-division multiple-access (O-CDMA) packet network is considered, which offers inherent security in the access networks. Two types of random access protocols are proposed for packet transmission. In protocol 1, all distinct codes and in protocol 2, distinct codes as well as shifted versions of all these codes are used. O-CDMA network performance using optical orthogonal codes...

To meet the growing demands of the high data rate applications, suitable asynchronous schemes such as Fiber-Optic Code Division Multiple Access (FO-CDMA) are required in the last mile. FO-CDMA scheme offers potential benefits and at the same time it faces many challenges. Wavelength/Time (W/T) 2-D codes for use in FO-CDMA, can be classified mainly into two types: 1) hybrid codes and 2) matrix codes,...
