coax is 200 meter maximum ,if you want more than 200 meter(video transmission) you can even use cat 5 cable with video transmitter and receiver adapters and it will be the cheap and best way.

Thinnet 10BASE2 cable
In the IEEE standards, Thinnet is designated as 10BASE2. This specification refers to a form of Ethernet that uses coaxial cable with a maximum segment length of 200 meters and supports data rates of 10 Mbps. Thinnet is known for its thinner, more flexible cable compared to the original thick coaxial Ethernet (10BASE5), which allows for easier installation in various environments.
The maximum distance of 100BaseT, also known as Fast Ethernet, is 100 meters using twisted-pair cable. Beyond this distance, signal degradation can occur, affecting network performance.
The maximum length of a 1000 ft Ethernet cable for network connections is 328 feet.
325 feet
The maximum length of a cat 5 e cable with out a repeater is 100meters
50-ohm
In a Token Ring network, when using Shielded Twisted Pair (STP) cable, the maximum distance a computer can be from the Multi-Station Access Unit (MSAU) is 100 meters. This is an improvement over Unshielded Twisted Pair (UTP) cable, which is limited to 45 meters. The increased distance capability of STP is due to its shielding, which reduces electromagnetic interference.
Router having maximum bandwidth in network. and in network fiberoptic cable having max bandwidth for data travaling
