Warnings and Notices

WARNING

To avoid the possibility of injury or death, you must observe the following

precautions before switching on the instrument.

Insert the power cable plug only into a socket outlet provided with a pro

tective earth contact. Do not negate this protective action by the using

an extension cord without a protective conductor.

WARNING

Never look directly into the end of a fiber or a connector, unless you are

absolutely certain that there is no signal in the fiber.

Getting Started Introduction

10 Agilent 86038A Optical Dispersion Analyzer, Third Edition

Introduction

The 603 A optical dispersion analyzer (ODA) is designed to take you into

the future of optical dispersion measurements. It is designed specifically

for the development of a wide range of devices including DWDM

components, dispersion compensating gratings, optical fiber, amplifiers,

and systems.

Key benefits are:

• Simultaneous PMD, CD, GD, PDL, and IL measurements with a single connec-

tion and single setup reduces measurement time and test uncertainness.

• Excellent group delay repeatability, differential group delay accuracy, gain/loss

accuracy, and wavelength accuracy . Refer to Chapter , “Specifications and

Regulatory Information”.

• Extremely high speed swept measurements: CD and IL measurements of 1601

wavelength points can be obtained in less than 10 seconds.

• CD measurements are automatically corrected for PMD artifacts.

• Two port DUT testing allows simultaneous testing of two devices, two ports of

the same DUT, or simultaneous transmission and reflection measurements that

increase throughput.

• Wider operating wavelength range: 1260 to 1640 nm (O to L band)

• Specified operation: 1510 to 1620 nm

• Dynamic drift reduction provides excellent stability and accuracy when the

environmental conditions of the room or the test device are gradually changing.

• Automatic modulation frequency selection saves measurement time by auto-

matically choosing the best modulation frequency and avoiding phase wrap

errors for fiber test.

• External CDRW drive allows you to easily store data.

Proceed to “Setting Up the Optical Dispersion Analyzer” on page 16 for

complete installation instructions.

To get the most performance out of your ODA, it is recommended that you

read Chapter 2, “Measurement Concepts”, Chapter 3, “Making

Measurements”, and Chapter 4, “Function Reference”. These three

chapters cover the linkages between the different measurements that can

be made, specific devices being measured, and the setup parameters used

to make the measurements.
