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
