They offer next-generation Ethernet services without
the cost and complexity of fiber deployments, but also without the unlimited bandwidth
and unlimited reach of fiber deployments.
Copper-based technologies always have rate/reach limitations, meaning that customers
farther from the serving office have less bandwidth potential than customers closer
to the serving office; you have to trade rate to get reach and vice versa. This is a result
of signal dissipation across the copper wires. VDSL2, for example, can deliver 100 Mbps
on a single pair of copper, but only at very short distances (less than a 1000 ft). The
higher the rates required, the smaller the service radius.
Mid-Band Ethernet has improved upon normal copper limitations by allowing multiple
pairs of copper to be aggregated into a single connection. This improves the service
radius, but doesn??™t remove it. Optical connections, on the other hand, have a relatively
unlimited service radius??”different optical transceivers can be used to cover hundreds
and hundreds of miles. So the use of Mid-Band Ethernet services will always have distance
and speed shortcomings when compared to optical services.
