About the FDDI Fiber Single Ring and Dual Ring Adapters
The FDDI Fiber Single Ring (Type B2-R for MCA Adapter), see Figure 3, and the FDDI
Fiber Dual Ring (Type B2-S for MCA Adapter, see Figure 4, use a MIC fiber optic cabling
connection to integrate fiber optic/Micro Channel systems with the 16/32–bit MicroChannel
bus architecture via a FDDI concentrator into 100Mbps FDDI fiber optic network.
The FDDI Fiber Single Ring (Type B5-4 for PCI Adapter), see Figure 5, and the FDDI Fiber
Dual Ring (Type B5-5 for PCI Adapter), see Figure 6, use a SC fiber optic cabling
connection.
The boards comply with ANSI standard X3T9.5. The FDDI Fiber Dual Ring Adapter allows a
station integration in the dual FDDI Ring.
