An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building.

DAS is a block device from a disk which is physically [directly] attached to the host machine. You must place a filesystem upon it before it can be used. Technologies to do this include IDE, SCSI, SATA, etc.

SAN is a block device which is delivered over the network. Like DAS you must still place a filesystem upon it before it can used. Technologies to do this include FibreChannel, iSCSI, FoE, etc.

NAS is a filesystem delivered over the network. It is ready to mount and use.
Technologies to do this include NFS, CIFS, AFS, etc.
