Glossary

singlemode optical fiber

An optical fiber that allows one wavelength-dependent mode (light path) to propagate. Contrast with multimode optical fiber.

small computer system interface

SCSI. An interface standard that enables computers to communicate with peripherals connected to them. Commonly used in enterprise computing and in Apple Macintosh systems. Usually pronounced as “scuzzy.” The equivalent interface in most personal computers is enhanced integrated drive electronics (EIDE).

A narrow SCSI adapter supports up to eight devices, including itself. SCSI address 7 has the highest priority followed by 6, 5, 4, 3, 2, 1, 0, with 0 being the lowest priority.

small form factor pluggable transceivers

SFP transceivers. Laser-based optical transceivers for a wide range of networking applications requiring high data rates. The transceivers, which are designed for increased densities, performance, and reduced power, are well-suited for Fibre Channel applications.
