Hi Guys,
I need to have a high rate data transfer of about 10Mbps on a twisted-pair wired line over a long distance of about 1500 meters.
From my searches, I came to the conclusion that over the long haul, protocols like the RS485 did not meet my needs.
I think I should use parts that do some sort of signal modulation and demodulation themselves.
Can anyone introduce components or modules to do this?
so thanks.
Hello,
what about "CAN FD" (the newest CAN standard). It has max. data transfer rate close to your requirements (8Mbps). I am using "CAN FD" in my newest project based on STM32MP157A MCU and it is working fine so far. Earlier I had been using CAN 2.0. "CAN FD" has higher speed comparing to CAN 2.0B standard and also longer frame - up to 64 byte versus 8 byte . And it is relatively simple in use.
Regards
BTW: second alternative could be some kind of "TCP/IP" protocol over twisted pair - what was mentioned by coleagues in posts above
Can anyone introduce components or modules to do this?
1) "CAN FD" is specified for 10 meters maximum distance, the requirement here is 1500 meters. Also, the expected average bit rate is probably below 4 Mbit/s:

2)"TCP/IP" is a (software) protocol, and has nothing to do with transferring bits on the physical layer (the twisted pair).
