Internet last mile access
The VDSL2 technology also deployed at the last mile of internet access; the
ISP uses the fiber cable as backbone uplink to the basement of building
(FTTB) or corner of streets (FTTC) and uses the exist 1 pair twisted cable of
POTS system to carry voices and Ethernet data stream for user via VDSL2
signal.
Intelligent Traffic System application
In the Intelligent Traffic system (ITS), the VDSL2 technology could be
applied in the long distance data transmission for traffic signal control or
traffic information signboard. JetCon 2502 can save the deployment cost of
fiber by using the twisted cable up to 3000 feet at DS/US data rate 35Mbps /
8Mbps for low speed data transmission over the Ethernet link distance.
Subway & Railway System application
JetCon 2502 can also be applied in the subway and railway system to offer
long distance transmission with low data traffic; for example, the Fire Alarm
System (FAS) and Passenger Information Direction System (PIDS) use the
VDSL2 technology to communicate between outdoor device and Control
Room to replace the fiber cable and save the cost of deployment
