Step 5. Performing an operational check

CAUTION

Improper connector care, cleaning, or use of mismatched cable connectors can

invalidate the published specifications and damage connectors. Clean all cables

before applying to any connector. Repair of damaged connectors due to

improper use is not covered under warranty. Refer to “Cleaning Connections

for Accurate Measurements” on page 1-12 for proper cleaning procedures.

Return loss

Return loss can be tested using a number of different test equipment configu-

rations. Some of these are:

• an Agilent 8703A lightwave component analyzer

• an Agilent 8702B lightwave component analyzer with the appropriate source,

receiver and lightwave coupler

• an Agilent 8504B precision reflectometer

• an Agilent 8153A lightwave multimeter and Agilent 81534A return loss module

Many other possibilities exist. The basic requirements are an appropriate

lightwave source, a compatible lightwave receiver, and a compatible lightwave

coupler.

Refer to the manuals provided with your lightwave test equipment for infor-

mation on how to perform a return loss test.

Typical return loss is better than 40 dB. For actual specifications on your par-

ticular cable or accessory, refer to the manufacturer.

Insertion loss

Insertion loss can be tested using a number of different test equipment config-

urations. Some of these are:

• an Agilent 8702B or Agilent 8703A lightwave component analyzer system with

a lightwave source and receivers

• an Agilent 83420 lightwave test set with an Agilent 8510 network analyzer

• an Agilent 8153A lightwave multimeter with a source and a power sensor mod-
