Cladding The dielectric material surrounding the core of an electrical fiber or material surrounding the core of a fiber optic cable. It usually refers to diameter, often 125 m measured in microns.

Connector A mechanical device used to align and join two fibers together to provide a means for attaching and decoupling it to a transmitter, receiver, or another fiber.

Core The central region of an optical fiber through which light is transmitted.

Custom Device Module (CDM) A CDM is the driver component in the NetWare Peripheral Architecture used to drive specific storage devices attached to the HBA.

The NPA separates NetWare driver support into two components: a Host

Adapter Module (HAM), and a Custom Device Module (CDM).

Data Rate The maximum number of bits of information that can be transmitted per second in a data transmission link. It is typically expressed as Megabits per second (Mbps).

Device Driver A software program that enables a personal computer to communicate with hard drives, CD-ROM drives, printers, and other peripherals. Device drivers are stored on a hard drive and are loaded into memory at boot up.

Duplex Cable A two-fiber cable suitable for duplex transmission or transmissions in two directions.

Duplex Transmission Transmission in both directions, either one direction at a time (half duplex) or both directions simultaneously (full duplex).

Fabric A fibre channel interconnection method that allows multiple simultaneous and concurrent data transfers between multiple hosts and/or storage devices connected with a multi-port hub.

FC-ALAbbreviation for Fibre Channel Arbitrated Loop, an interconnection scheme that supports from 1 to 126 ports on a loop in a shared medium topology.

FCP Fibre Channel Protocol.

FDDI Fibre Distributed Data Interface. A network based on the use of optical-fiber cable to transmit data at 100Mbit/sec.
