(2) 10BASE-T cable
The 10BASE-T cable contains several twisted-pair cables or pairs of stranded copper wires and
is covered by an external protective jacket. This cable is divided into the following types:
• Shielded STP cables and unshielded UTP cables
• Cross cables for making direct connections between nodes and straight cables for making
connections via a hub
The maximum transfer speed provided by the 10BASE-T cable is 10 Mbps. The maximum
permissible cable length is 100 m. The cable is to be terminated on both ends with 8-pin
modular connectors that are stipulated in the ISO 8877 standard. Also, be sure to use
Category 5 10BASE-T cables.
(3) 10BASE-T/optical media converter/repeater
The 10BASE-T/optical media converter/repeater converts an electrical signal on a 10BASE-T
cable to an optical signal.
Typical examples are the FOIRL (Fiber-Optic Inter-Repeater Link) for inter-repeater connection
and the 10BASE-FL for connection to a terminal. The 10BASE-T/optical media
converter/repeater is used, for instance, for noise immunity assurance or cable extension.
