Universal Media Converter and
Repeater
AMC-101
DESCRIPTION
•
The AMC-101, Universal Media
Converter, provides retimed or
transparent conversion of optical
and electrical signals for ATM,
FDDI, Fast Ethernet and other
protocols at data rates up to
155 Mbps. The modularity of the
AMC-101 interfaces enables
field changeable conversion
between any two media.
•
Both transparent modules and
retimed modules are supported.
Transparent modules provide
cost-effective media conversion
without reclocking. Retimed
modules provide media
conversion with reclocking,
which enables using AMC-101
as a repeater.
APPLICATIONS
RETIMED MODULES
•
AMC-101 provides retimed
media conversion for the
following ATM interfaces: STS-1
(51 Mbps), TAXI (100 Mbps) and
STM-1/STS-3C (155 Mbps) over
optical and electrical interfaces.
Retimed conversion is also
available for FDDI and Fast
Ethernet
(100 Mbps).
•
The retimed modules provide
rate selection for 51, 100 or
155 Mbps. When set to one of
these rates, the retimed module
regenerates and reclocks the
incoming signal and acts as an
ATM, FDDI or Fast Ethernet
repeater.
TRANSPARENT MODULES
•
AMC-101 provides transparent
conversion for any two-level
optical protocol.
•
Transparent modules are
recommended for short
distances and for all applications
performed at less than 100
Mbps.
•
AMC-101 can be used to convert
between different media
(see
Figure 1
). A single AMC-101
converter with different media
modules is used to connect two
devices operating with dissimilar
fiber or electrical interfaces.
Either transparent or retimed
modules can be used.
•
AMC-101 can be used as a
repeater for extended distances
(see
Figure 2
). A single AMC-101
can be used as a fiber optic or
copper repeater for ATM or
FDDI and Fast Ethernet, when
installed with two similar retimed
modules
(B1 and B2).
