Fiber optic connection for program-controlled exchanges
FICON channels use five classes of IUs to conduct information transfers between a channel and a control unit. They are: Data, Command, Status, Control, and lastly Link Control. Only a channel port may send Command or Command and Data IUs, while only a control unit port may send Status IUs.OverviewFICON (Fibre Connection) is the proprietary name for the FC-SB-3 Single-Byte Command Code Sets-3 Mapping Protocol for (FC). It is a FC layer 4 protocol used to map both I. Each FICON channel port is capable of multiple concurrent data exchanges (a maximum of 32) in full duplex mode. Information for active exchanges is transferred in Fibre Channel sequences mapped a. FICON may employ Fibre Channel fiber optic cables with either short wavelength (multi-mode; 62.5 or 50 micrometer core) or long wavelength (single mode; 9 micrometer core). Long wavelength is used in the majo. -
