have been widely used in FTTH, FTTP, and even transportation
automation, power system automation, as well as many other
automation systems. The main reason is because fiber optic
communication has ESD immunity, wide bandwidth, zero data
loss, and can transmit data over a much longer distance
compared to wire cabling.
Media converters are generally used
in a pair connection. That is, two media converters
are used in tandem, with one converter located at the
control center, and the other converter located at a
remote site. This is the ideal setup from a central
management point of view, in which all data is transmitted
back to the control center for processing in a central
computing system. For systems that require many media
converters at the central site, system integrators must
determine how and where to mount the converters and
how to arrange power supplies.
Chassis-type media converters are
a perfect choice for systems that require installing
several converters in a confined space. Moxa's NRack System™ is designed to help customers who are faced with
the challenge of installing a high density media converter
system. The NRack System™ saves time since less mounting
is required, and the power input wiring problem is much
easier to handle.
An NRack System™ consists of 3 major components: Rackmount
Chassis, Slide-in Modules, and Power Supply Modules.
Installing the power supply module in the chassis can
save quite a bit of space since you do not need to deal
with numerous power adaptors connecting to the various
converters installed in your control center. Two main
types of slide-in modules are available. One type handles
data transmission only, whereas the other type is used
to manage the entire chassis system.
