High-definition video (also known as high-definition television, HDTV, or simply HD) offers much more detail in video images because it uses many more pixels than standard video. These added pixels allow much larger video displays to be used without the loss of sharpness that can come from simply enlarging a standard-definition video signal.

In order to satisfy the explosive demand for high bandwidth, the IEEE 802.3ba task force has defined 100 Gbps Ethernet standard requirement for demanding applications such as ultra-high definition video streaming, large file sharing and video conferencing (1). Currently, research towards extending present networks by increasing channel data rates as well as wavelength multiplexing is considered a viable approach to increase capacities of optical fibre networks. For instance, the 100 Gbps Ethernet standard is based on 4 channels at 25 Gbps data rates in wavelength division multiplexing (WDM) systems with channel spacing of 5 nm for the metro-access networks.
