System Configuration
10Base-5 Specifications
The 10Base-5 standard is an Ethernet connection method that uses thick coaxial cable (yellow cable) with a
width of approximately 10 mm. The "10" in 10Base-5 indicates a baud rate of 10 Mbps. "Base" indicates that a
baseband transmission method is used. The "5" indicates a transmission distance of 500 m for the trunk line.
Coaxial cable is connected to a transceiver, which is then connected to the personal computer or other devices
via transceiver cable (AUI cable).
10Base-5 Ethernet is not easy to lay due to the thick cables. Therefore, this method is hardly used in office net-
works. 10Base-5 is often used in trunk line networks, however, due to its long transmission distance.
The following diagram shows a 10Base-5 Ethernet configuration example.
10Base-T Specifications
The 10Base-T standard is an Ethernet connection method that uses twisted-pair cable. The "10" in 10Base-T
indicates a baud rate of 10 Mbps. "Base" indicates that a baseband transmission method is used. The suffix "T"
indicates that twisted-pair cables are used as the transmission media. Personal computers and other devices
in a 10Base-T network must be connected in a star connection via a hub. Direct connections between devices
are not supported. (Special cables called cross cables can be used for 1:1 direct connections, but such con-
nections are not commonly used.) The cable length from the hub to each device is 100 m maximum.
10Base-T Ethernet uses thin cables, making it easy to lay the network. This method is often used in office net-
works because each device can be easily connected and removed from the network.
The following diagram shows a 10Base-T Ethernet configuration example.
