However, the carrier must understand the limitations of each
technology as described next.
Target Carriers
Mid-Band Ethernet technologies target carriers that have access to outside copper
plant loops, generally incumbent carriers and competitive carriers. Cable providers,
because they generally have a fiber/coax plant and no outside plant copper, are not the
intended targeted provider for most Mid-Band Ethernet services.
140 Chapter 5
The exception to this is, of course, the in-building application of Mid-Band Ethernet,
where Ethernet services are delivered up the riser to multiple tenants over the existing
phone wiring. Any carrier with a building presence can benefit from a high-speed,
existing distribution network.
Optical End-Game
In an ideal world, all services are delivered over all optical networks. Unfortunately, we
don??™t live in an ideal world. Mid-Band Ethernet technologies are not meant to compete
with fiber-based Ethernet deployments??”optical connectivity will always deliver the
highest amount of bandwidth possible. However, the Mid-Band Ethernet technologies
can be used to complement fiber deployments and ensure that Ethernet services are
delivered quickly and cost effectively today.
