Glossary
Optical Waveguide
Dielectric waveguide with a core consisting of optically transparent material or
low attenuation (usually silica glass) and with cladding consisting of optically
transparent material of lower refractive index than that of the core. It is used for
the transmission of signals with lightwaves and is frequently referred to as fiber.
PCI Bus #
An internal Peripheral Connect Interface bus number in a computer. PCI Bus # is
set by the computer system's BIOS, and in most cases, the number is zero.
PCI Device #
PCI slot number in a computer.
Point-To-Point (PTP)
A connection established between two specific locations, as between two
buildings.
Protocol
A data transmission convention encompassing timing, control, formatting, and
data representation.
SCSI
Small Computer Systems Interface.
SelectID
Used to configure Seagate drives. A matrix for relating ALPA (hex) numbers to
SelectID (hex) numbers.
Shortwave
Refers to length of the wave or frequency in the spectrum of light. 780 nm is the
operating range of short wave lasers, while 1300nm describes the range of long
wave lasers.
Simplex Cable
A term sometimes used for a single-fiber cable.
Simplex Transmission
Transmission in one direction only.
Single-Mode Fiber
An optical waveguide (or fiber) with a small core diameter in which only a single
mode is capable of propagation. This type of fiber is particularly suitable for
wideband transmission over large distances, since its bandwidth is limited only by
chromatic dispersion.
Topology
The logical and/or physical arrangement of stations on a network.
