7 Special ParBERT Systems Installing Optical Modules
7-16 Agilent 81250 ParBERT Installation Guide, May 2004
Please pay attention to the following laser safety warnings:
•
Under no circumstances look into the end of an optical cable attached
to the optical output when the device is operational. The laser
radiation can seriously damage your eyesight.
•
Do not enable the laser when there is no fiber attached to the optical
output connector.
•
The laser is on when the green LED on the front panel is lit.
•
The use of optical instruments with this product will increase eye
hazard.
•
Refer servicing only to qualified and authorized personnel.
Installing E4810A/E4811A Electrical-Optical
Modules
These modules are capable of generating or analyzing electrical or optical
data streams at 21 Mbit/s up to 3.35 Gbit/s.
They cannot be used in conjunction with an E4805B clock module. They
have no replaceable frontends. For these modules, one channel means
one module.
The ParBERT user software allows you to switch between optical and
electrical operation. For optical operation, cable connections have to be
made at the front panels.
Connections of an E4810A Electrical-Optical Module
This data generator module consists of an electrical signal generator and
an electrical-to-optical (E/O) converter. The electrical signal generator
can provide a differential signal.
