Intelligent transportation is a service system for transportation based on modern electronic information technology. Its outstanding feature is to collect, process, release, exchange analysis and use information as the mainline, to provide diversified services for traffic participants. Traffic junction equipment is various, so the difficulty of communication is big. Expanding capacity upgrading is more difficult and brings not small problem to construction unit.

The new closed-circuit copper cable transmission method can effectively solve the problem in the above transmission part. Ethernet Extender is installed on the existing copper cable to transmit the network data signal.
Power Line Ethernet Extender Item OT-PLC302C-RS4

Product Features:

1. Support point-to-point and point to multi-point communication

2. Max transmission distance can reach 600m (RVS 2×1mm2)

3. Max physical bandwidth can reach 500Mbps

4. Plug and play, excellent anti-interference ability

5. Support RS485 data transmission, and offer 12VDC output

Solution Advantages:

Convenient installation: only use 220V power line to connect, no extra setting, simple installation.

High bandwidth: The general bandwidth of 100M network signal is 100Mbps while this Ethernet Extender can support 94Mbps bandwidth in real time. It can satisfy the signal transmission up to 600 meters.

Quick construction: Use the power line to connect this Ethernet Extender, no need to rewire and pipe, greatly reduce the number of workers, do not affect other work.

Convenient expansion: Support point-to-point and point to multi-point communication. Also support RS485 data transmission over the power line.

Strong anti-interference ability: This Ethernet Extender with a dedicated network data processing chip, can make the network signal modulated and frequency shift in order to increase its anti-interference ability. So it can work in various complex environments.

The practical application of Ethernet Extender

Power Line Ethernet Extender can transmit network signal of network data, network video, network digital television, and industrial network data under IP/TCP Internet protocol, applied in any 100M network system construction and topology projects.

In the case of intelligent transportation system, the network HD camera and 485 controller in the system all need the support of network data. However, some intersections are relatively wide, and the cable transmission distance is more than 100 meters, so it is limited by using the network cable. If the fiber optic cable is laid, the problems of long cycle, traffic impact, repeated breaking of road surface and high cost will occur.
