The main technology used here is the Hybrid Passive Optical Network (Hybrid PON) which provides longer reach and a higher data rate. Wavelength Division Multiplexing (WDM) PON can make the transmission through optical fiber possible for a long distance at a high data rate. A Hybrid PON utilizes the advantages of WDM-PON as well as share the same wavelength with a number of users. This research basically aims at improving the data rate and in increasing the reach of such a network by using different modulation techniques and amplifiers. Normally On-Off Keying (OOK) is used in such an access network scenario. We have analyzed the effect of the Differential Quadrature Phase Shift Keying (DQPSK) line technique in comparison to the usual On-Off Keying (OOK) technique with and without Erbium-Doped Fiber Amplifier (EDFA).

The need for bandwidth is also increasing at a rapid rate. The bandwidth and speed with which data can be transferred was very less when compared to core networks. The access network which was once a bottleneck is no longer so because of use of optic fiber (FTTH networks). A number of variants of Passive Optical Network (PON) have been proposed like the WDM PON and the Hybrid PON. Hybrid PON is a combination of TDM PON and WDM PON and is advantageous over WDMPON. This paper focuses on high capacity networks that can provide high data rate and long reach in the access part of the network. NRZ modulation format is normally used for transmission. We consider the advantages provided by the advanced modulation formats like DPSK. This modulation format is used to here and its benefits are evaluated in Hybrid PON network to increase the capacity and the reach of the network. Parameters like the BER and the Q factors are a...

Passive Optical Networks (PON) in particular, Ethernet PON (EPON) networks based on Time Division Multiple Access (TDMA) are more prominently used in many parts of the world. Though Wavelength Division Multiplexing (WDM) PON has its own advantages, considering the cost and utilisation of such networks in the access part makes it less useful. On the other hand, Hybrid PON network combines the advantages of both EPON and WDM PON Networks. The objective of this paper is to identify suitable electrical filters for a 16-channel Hybrid Passive Optical Network with a transmission rate of 10Gbps per channel, by analysing their performance in terms of Q factor and Bit Error Rate. Different filters like the Bessel filter, Gaussian filter, Raised Cosine Filter, Rectangular filter, Butterworth filter, Chebyshev Filter are compared and their performances are evaluated. DB...
