Step 5. Performing an operational check

Step 5. Performing an operational check

C A U T I O N

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 “Care of Fiber-Optic
Connectors” on page 1-13 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 HP 8703A lightwave component analyzer

• an HP 8702B lightwave component analyzer with the appropriate source, re-

ceiver and lightwave coupler

• an HP 8504B precision reflectometer

• an HP 8153A lightwave multimeter and HP 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 HP 8702B or HP 8703A lightwave component analyzer system with a light-

wave source and receivers

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

• an HP 8153A lightwave multimeter with a source and a power sensor module
