A pair of AMC-101 converters
can be used to connect two
similar ATM devices over a
different media type using
retimed modules B1 and B2 (see
Figure 3)
.
•
The FDDI and Fast Ethernet
(100Base-T) standards apply
scrambling to data when
operating over UTP, but do not
apply it when operating over
fiber. As a consequence, AMC-
101 cannot convert between
UTP and fiber for the two
protocols. In this situation, it is
recommended that a pair of
AMC-101s be used to convert
from UTP to fiber optic and then
back to UTP. This extends the
FDDI-UTP (CDDI) and 100Base-
T over fiber using retimed
modules. Alternatively, 100BT/B
and 100BT/R modules can be
used for 100Base-Tx to
100Base-Fx conversion.
•
AMC-101 can be used in
applications of Ethernet or Fast
Ethernet remote bridging over
long distances (see
Figure 4
).
Modules A1 and A2 can be
AMC-100BT/B or AMC-10BT/B.
Modules B1 and B2 can be any
transparent (for Ethernet) or
retimed (for Fast Ethernet)
optical modules.
•
AMC-101 can be used to
connect two ATM devices over a
single fiber (see
Figure 5
). A pair
of AMC-101s is used to connect
two ATM devices where the
physical link is a single fiber. In
this application, modules B1 and
B2 are using the WDM
technology, where the transmit
signal is at a different
wavelength than the receive
signal. Modules A1 and A2 can
be any modules.
Modules B1 and B2 can be a
pair of AMC-M/SM/**/SF1 and
AMC-M/SM/**/SF2.
•
AMC-101 is supplied as a
standalone unit. Special
hardware for mounting either a
single unit or two units side-by-
side in a 19" rack can be
ordered separately (see
Ordering
).
