Ethernet in the first mile (EFM) overview
Ethernet in the First Mile (EFM), is a collection of protocols (IEEE 802.3ah)
for Ethernet access and management technology across both the copper and
fiber network infrastructure.
Principally, EFM was established to enhance subscriber access networks.
EFM technology provides the following benefits:
•
Ethernet interfaces and transport over previously unsupported media,
such as single pairs of telephone copper wires
•
A universal Ethernet service extending the reach of Ethernet to locations
served by both copper and fiber
•
A consistent set of Ethernet services with adjustable bandwidth and rates
from 1 Mbps to 10 Gbps.
2BASE-TL
EFM over Copper (EFMC) is a point-to-point Ethernet over copper standard
targeted at small to medium enterprise sites served by copper. The two
protocols associated with EFM are: 2BASE-TL and 10PASS-TS. Zhone
currently supports only 2BASE-TL. The following table provides details
about 2BASE-TL.
