Ethernet network termination unit is the undisputed, global choice for Metro Access Networks (MANs) and Local Access Networks (LANs). However, existing copper access networks do not facilitate an end-to-end high-bandwidth connection, creating a bottleneck. This bottleneck is the first mile of access. This refers to the access link (most often a TDM-based copper circuit) from the business customer’s office LAN to their service provider’s MAN. It affords service providers the ability to remove this bottleneck through the utilization of an improved data transmission standard.
