Scale up to a ONE Gigabit Network 
Today's traffic surveillance technology plays an essential role in
both accident detection and traffic management, thanks in
large part to the rapid growth in the practice of transmitting
video, voice, and data
over Ethernet and the Internet. Before IP networks
became prevalent, video, voice, and data were managed
using completely different protocols and systems (including
analog systems). Due to the current demand
for delivering video, voice, and data over ONE network for
traffic surveillance
applications, system integrators are always on the lookout
for networking products that support larger
bandwidths and greater media versatility.
One of the requirements called for most often is gigabit
Ethernet, which
can be used as a backbone to provide a higher bandwidth network
for traffic surveillance applications, to ensure that all
information is transmitted smoothly.
Maximize the Transmission Distance
Surveillance cameras at major intersections provide an effective means of
reducing red light violations, and as a result improve transportation
safety dramatically. In addition, by sending data from multiple intersections
to one
central
control room, traffic engineers can better control traffic
flow and reduce traffic jams. However, most computers in
the central control room use gigabit
LAN
adaptors
with
RJ45
connectors
to connect to each other, and the 100-meter
limit for transmitting data over twisted pair
cable makes it difficult to link to remote sites. Since the
distance from intersections to the central
control room could be as much as
40 kilometers, using twisted
pair cable would require installing Ethernet switches
every hundred meters or so, making maintenance both difficult
and expensive. The IMC-101G gigabit media converter is an attractive and economical solution
to this problem, since the transmission
distance can be extended up to 80 kilometers (over single mode fiber) at gigabit speed. As an added benefit, each
IMC-101G converter comes supports Link Fault Pass-Through
to ensure
that the
network runs non-stop, and to give system maintainers an
efficient means of troubleshooting broken links.
