I am currently developing a monitoring system using Arduino Nano with a 7-segment output over a long distance using cables. However, during runtime, the output becomes unclear and there is noise. Do I need to add something to my circuit?
Post your project schematic,
and using tags clicking " < code > " post your code.

Order a bunch of parts, it sounds like you will be frying them. As requested post an annotated schematic showing exactly how this is wired and note any leads over 10"/25cm in length. What type of environment is this going to work in?
When I try it in the room, the condition of the seven-segment appears normal and there is no noise. However, when I connect the cable and the seven-segment with a distance of 10 meters, following the existing route, there is noise on the seven-segment like random numbers continuously appearing. Do I need a step-up? Or is there some error in the quality of the TM1367?
I would be very surprised if you were ever successful in using an I2C like interface over the length of 10 metres at any kind of useful clock rate. That kind of bus is intended for short distance intra-board communication, not long distance inter-board communication.

I am surprised you have not fried something. Consider something like CAN or RS??? to talk the distance. You will need another micro on the display side but almost any Arduinos would work.
