[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

(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:
