DESCRIPTION
This presentations give's you an clear picture of optical communications in broadband using single mode and multi mode fibers and different possibilities to increase broadband speed max down link speed is 2.5 Gbps and up-link is 1.25 Gbps possible with latest technologies

Option for increasing the bandwidthMore Fibers -Installing new fibers
Same bit rate, more fibers
Faster Electronics (TDM)-Increasing the bit rate Higher bit rate, same fiber
WDM -Increasing the number of wavelengthsSame fiber & bit rate, more wavelengths
What is FTTH?
CopperFiber
Limited to few Mbps
Old networks, optimized for voice
CO/HE
19 Mbps - 1 Gbps +
Optical networks, optimized for voice, video and data
CO/HE//
