|Transmission speed/data link control||1Gbps/based on Ethernet standard|
|Network topology/reliability||Dual loop, fiber optic cable|
|Media||IEEE 802.3z multimode fiber optic cable (GI)|
|Connector||IEC 61754-20, LC connector|
|Media access control||Token passing|
|Size of network common memory||Up to 256K bytes|
|Number of stations per network||Up to 120 stations|
|Distance between 2 stations||Up to 550 meters cable length|
|Number of interconnected networks||Up to 239 networks (w/120 stations ea.)|
