A communication system for providing high speed data services to a
subscriber using optical fibers comprises a first optical interface unit
(OIU) and a second OIU. The first OIU transmits optical representations
of signals from an electrical communication path to the second OIU, which
forwards electrical representations of those signals to a subscriber. The
second OIU transmits optical representations of electrical signals from
the subscriber to the first OIU, which forwards those signals to the
electrical communication path. The second OIU further forwards electrical
representations of another received optical signal to the subscriber. In
one embodiment, the first OIU is located at a network node element such
as a HDT, for example. In another embodiment, the second OIU is located
at an optical node device such as an ONU, for example.
