JetCon 2502


Ideal Ethernet /Voice Extender
JetCon 2502 is an Ethernet/POTS to VDSL2 (Very High-Rate Digital Subscribe Loop -2) extender and is compliant with ITU-T G.993.2 standard. It allows carriers to deliver Ethernet data up to 100Mbps in both upstream and downstream over existing twisted copper. The Ethernet/POTS (Plain Old Telephone Service) converter features Discrete Multi -Tone modulator/ de-modulator and VDSL Analog Front End (AFE) technology; it is an ideal solution to carry POTS signal and Ethernet Data stream to 3000 feet to extend local LAN and voice on the same line.

Economical and Simple Connection
To deploy VDSL2 access with the telephone network, the VDSL2 converter should follow the line impendence of telephone network. Therefore, each region will adopt different line splitters to provide best communication quality. As a result, users need additional wiring and splitter, but mostly need to make a jumble at home and office. To solve this problem, the JetCon 2502 has implemented splitter for each region to save your installation time and make it more easily to connect.

Central and Discrete Internet Access
For the network inf rast ructure, JetCon 2502 is the best choice for planning centralized internet access through the existing POTS wiring system for hotels, dormitories or for places where there is a need to extend LAN over 100m over a single pair of copper path.

Triple Play – HDTV, Data Access, Video conference
JetCon 2502 allows users to compete with wireless and satellite providers by offering outstanding service, such as Video conference, HDTV or Video chatting over an existing telephone copper cable without any configuration, just plug and play to enlarge infrastructure for your applications.

Internet Last Mile Access

The VDSL2 technology is 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 existing 1 pair twisted cable of POTS system to carry voice and Ethernet data stream to users via VDSL2 signal.

Intelligent Traffic System application

In Intelligent Traffic systems (ITS), the VDSL2 technology could be applied in the long distance data transmission for the traffic signal control or traffic information signboard. JetCon 2502 can save the fiber cost by using the twisted cable up to 3000 feet at DS/US data rate 35Mbps / 8Mbps for low speed data transmission but over the Ethernet link distance.

Subway & Railway System application

JetCon 2502 can also be applied in the subway and railway system to offer a long distance transmission with low data traffic, such as the Fire Alarm System (FAS) and Passenger Information Direction System (PIDS) with the VDSL2 technology to communicate between outdoor device and Control Room to replace the fiber cable and therefore save more costs.
