The main diference is the smaller the glass core, the grater the distance data can travel. When it comes to cabling, Fiber is available as a single mode or multi-mode cable. FCP – Fibre Channel Protocol is used to denote the SCSI over Fibre Channel. FC-4 – Provides mapping of Fibre Channel capabilities to Upper Layer Protocols.Common Fabric Services Defines advanced features, such as stripping and hung group Flow control is handle by buffer-to-buffer control credit. We need flow control to check how much data we can send at a given time, so the receive side can handle all the request. FC-2 – Create FC Frame and flow control.FC-1 – Contains specifications for encoding, ordered set, and link control communications.FC-0 – Describes the physical media + the speed in which that device can communicate (1,2, 4, 8, 10, 16 Gbps).It does not follow the OSI model, although it is quite similar. Fibre Channel Protocol is split into five layers.
