The development of 100GbE, like 10GbE and 1GbE
before it, is being driven by bandwidth exhaustion.
At first glance, the development cycle of 100GbE
seems to mirror earlier 10GbE and 1GbE efforts, but
there are several key areas where 100GbE breaks
new ground. For the first time, the bandwidth of the
data stream is on the same scale as color channel
spacing. Thus, new spectrally efficient modulation
techniques can be employed. Also, MAC and PHY data
rates have been separated. Any PHY rate can be
used, enabling efficient channelization. For the first
time, a new Ethernet standard has been optimized for
networking and computing applications. On the
surface, 100GbE is just the latest speed boost for
Ethernet, but if you dig deeper you will find that
100GbE offers much more. Read on to discover the
promise of 100GbE....more
