Glossary 61

NDSF

non-dispersion-shifted fiber

A type of optical fiber optimized for the 1310 nm transmission window.

nanometer

See nm.

nm

nanometer

One billionth of a meter (10-9meter). A unit of measure commonly used to express the wavelengths of light.

node

A point in an optical network where optical signals can be processed and switched among various links.

NZDSF

non-zero-dispersion-shifted fiber

A type of optical fiber optimized for high bit-rate and dense wavelength-division-multiplexing applications.

OADM

optical add/drop multiplexer

An optical multiplexer/demultiplexer (mux/demux) that adds or drops one CWDM channel of the same wavelength from the optical fiber and allows all other wavelengths to pass straight through.

O/E

optical to electrical

Optical to electrical conversion.

OC

optical carrier

Series of physical protocols, such as OC-1, OC-2, and OC-3, defined for SONET optical signal transmissions. OC signal levels put STS frames onto fiber-optic line at a variety of speeds. The base rate is 51.84 Mbit/s (OC-1);
