And finally, the flexible and dynamic bonding mechanisms of
Mid-Band Ethernet can provide automatic resiliency against failures in the outside plant.
The Mid-Band Ethernet technologies can be economically compared to other access
options such as fiber optics, more traditional T1/E1 architectures, and traditional
xDSL. The primary drawback of fiber access is availability??”to extend the fiber network
requires a significant amount of capital and time. Trenching new fiber runs cost
between $50,000 and $250,000 per mile and takes between 6 and 24 months. With this
kind of up-front investment in time and money, it??™s easy to see why carriers aren??™t just
deploying fiber everywhere; there has to be significant revenue opportunity in order to
recoup the up-front costs.
Traditional T1/E1 technologies, on the other hand, are universally available but lack
both the capability to deliver significant bandwidth and the resiliency necessary for
highly reliable services. Mid-Band Ethernet technologies provide more than seven times
the raw capacity of a traditional T1. Additionally, once the efficiencies of native Ethernet
are included in the comparison, as compared to the overhead of frame relay, PPP, or ATM
solutions of the T1, Mid-Band Ethernet can provide more than 13 times the user throughput
experience??”a significant bandwidth increase compared to the 1.
