[4] Other Ethernet Specifications

(1) 10BASE2

10BASE2 is a connection method for creating an Ethernet network using a coaxial cable approxi-
mately 5 mm thick (This cable is also called a "Thin cable"). The "10" in "10BASE2" refers to a data
transfer speed of 10Mbps. The word "BASE" means that the data transfer system is a "base band
system." Finally, the "2" means that the data transfer distance of a trunk is limited to 185 m (approx.
200 m). In order to connect devices such as a personal computer, a T-branch BNC connector is
connected to each device, and a coaxial cable comes in on each side of the T. The figure below
shows a configuration example of a 10BASE2 Ethernet system.

(2) Optical Ethernet Specifications

Optical Ethernet is a connection method for creating an Ethernet network using an optical fiber cable
to transfer data. It can be used for distances over 500 m and in systems that must be immune to
noise. The following standard (IEEE802.3) connection methods are available: 10BASE-FP, 10BASE-
FB, 10BASE-FL, 10BASE-FX,1000BASE-LX, and 1000BASE-SX. The figure below shows a con-
figuration example of an optical Ethernet system.
