Safety –1
Safety Information, Instructions, and Symbols
Safety Information
Classification
The unit consists of an exposed metal chassis that is connected directly to earth via a power
cord and, therefore, is classified as a Class 1 instrument. Class 1 refers to equipment relying on
ground protection as a means of shock protection.
The following symbol is used to indicate a protective conductor terminal in the unit.
Disconnecting from Line Power
Some of the circuits are powered whenever the unit is connected to the AC power source (line
power). To ensure that the unit is not connected to the line power, disconnect the power cord
from either the power inlet on the unit’s rear panel or from the AC line-power source (receptacle).
The power cord must always be accessible from one of these points. If the unit is installed in a
cabinet, the operator must be able to disconnect the unit from the line power by the system’s
line-power switch.
Line Power Requirements
The unit can operate from any single-phase AC power source that supplies between 100 and
240 V at a frequency range of 50 to 60 Hz. The maximum power consumption is 25 W.

Safety –2
Safety Instructions
The following safety instructions must be observed whenever the unit is operated, serviced, or
repaired. Failure to comply with any of these instructions or with any precaution or warning
contained in the user’s manual is in direct violation of the standards of design, manufacture, and
intended use of the unit. JDS Uniphase assumes no liability for the customer’s failure to comply
with any of these safety requirements.
Before Initializing and Operating the Unit
þInspect the unit for any signs of damage, and read the user’s manual thoroughly.
þInstall the unit as specified in the Getting Started section.
þEnsure that the unit and any devices or cords connected to it are properly grounded.
Operating the Unit
Warning
To avoid the risk of injury or death, always observe the following precautions
before initializing the unit:
•
If using a voltage-reducing autotransformer to power the unit, ensure that the
common terminal connects to the earthed pole of the power source.
•Use only the type of power cord supplied with the unit.
•
Connect the power cord only to a power outlet equipped with a protective
earth contact. Never connect to an extension cord that is not equipped with
this feature.
•Willfully interrupting the protective earth connection is prohibited.
•
Never look into the end of an optical cable connected to an optical output
device that is operating. Laser radiation is invisible, and direct exposure can
severely injure the human eye. For more information, see the user’s manual
of the laser source in use.
•
Turning off the power to the device does not always block the externally
supplied radiation to the connector at the output of the unit.
•Do not use the unit outdoors.
•
To prevent potential fire or shock hazard, do not expose the unit to any
source of excessive moisture.
•Do not operate the unit when its covers or panels have been removed.
•
Do not interrupt the protective earth grounding. Any such action can lead to a
potential shock hazard that can result in serious personal injury.
•
Do not operate the unit if an interruption to the protective grounding is
suspected. In this case, ensure that the unit remains inoperative.
•
Use only the type of fuse specified by the manufacturer as appropriate for
this unit. Do not use repaired fuses, and avoid any situations that can short-

circuit the fuse.
•
Unless absolutely necessary, do not attempt to adjust or perform any
maintenance or repair procedure when the unit is opened and connected to a
power source.
•Repairs are to be carried out only by a qualified professional.
•
Do not attempt any adjustment, maintenance, or repair procedure to the
unit’s internal mechanism if immediate first aid is not accessible.
•
Disconnect the power cord from the unit before adding or removing any
components.
•
Operating the unit in the presence of flammable gases or fumes is extremely
hazardous.
•
Do not perform any operating or maintenance procedure that is not
described in the user’s manual.
•
Some of the unit’s capacitors can be charged even when the unit is not
connected to the power source.

Safety Symbols
The following symbols and messages can be marked on the unit (Table 1). Observe all safety
instructions that are associated with a symbol.
Table 1: Safety Symbols
Symbol Description
Laser safety. See the user’s manual for instructions on handling and operating
the unit safely.
See the user’s manual for instructions on handling and operating the unit safely.
Electrostatic discharge (ESD). See the user’s manual for instructions on
handling and operating the unit safely.
Frame or chassis terminal for electrical grounding within the unit.
Protective conductor terminal for electrical grounding to the earth.
WARNING
The procedure can result in serious injury or loss of life if not carried out
in proper compliance with all safety instructions. Ensure that all
conditions necessary for safe handling and operation are met before
proceeding.
CAUTION
The procedure can result in serious damage to or destruction of the unit if not
carried out in compliance with all instructions for proper use. Ensure that all
conditions necessary for safe handling and operation are met before proceeding.

Safety –5
Compliance
CE Compliance
The unit has been designed and tested to comply with directive 73/23/EEC and its subsequent
amendments by the European Community (EC or CE). The directive relates to electrical
equipment designed for use within certain voltage limits. It ensures that electrical equipment is
constructed with good engineering practice in safety matters.
The unit has been designed and tested to comply with directive 89/336/EEC and its subsequent
amendments. The directive relates to electromagnetic compatibility. It demands that
electromagnetic disturbance does not exceed a prescribed level; that the equipment be immune
to a prescribed level of ambient level of interference; that the equipment be protected against
electrostatic discharges; and that the equipment be immune to all electrical shock wave
disturbances. As of 1997, measures have been added to test for fire hazard, electric shock
hazard, and also external exposure to other forms of energy.
The requirements specified by directive 89/336/EEC are as follows. CE compliance requires that
the manufacturer or its authorized representative established within the Community affix the EC
conformity mark to the apparatus or else to the packaging, instructions for use, or guarantee
certificate. The EC conformity mark shall consist of the letters CE as specified and the figures of
the year in which the mark was affixed. This mark should, where appropriate, be accompanied
by the distinctive letters used by the notified body issuing the EC type-examination certificate.
Where the apparatus is the subject of other Directives providing for the EC conformity mark, the
affixing of the EC mark shall also indicate conformity with the relevant requirements of those
other Directives.

General Information and Specifications –6
General Information and Specifications
General Information
This user’s manual for the Model 320A 3 GHz O/E Receiver contains complete operating
instructions. The inspection report and a description of any customer-requested information are
found in the Customized Features and Test Data section.
The receiver (Figure 1) detects and converts optical signals into electrical signals for the
purpose of transmitter waveform analysis and testing, including error rate testing. It is optimized
for analysis of high-speed, low-level optical signals from single-mode fiber sources. The high
bandwidth (3 GHz) and high gain (2500 V/W) enable detection and analysis of up to 2.5 Gb/s
signals at levels down to below -30 dBm. The receiver is also equipped with a high-level input
port for direct connection of laser sources at power levels up to +3 dBm without overload. The
Model 320A 3 GHz O/E Receiver is the one solution that provides users with a low-cost, high-
quality instrument for optical eye pattern analysis and testing at low to high power levels.
Figure 1: 320A Receiver
The receiver consists of a 3 GHz bandwidth optical-to-electrical (O/E) converter (1100 to 1600
nm) and a 3 Gb/s limiting amplifier. The detector out port for the O/E converter is DC coupled
and automatically nulled to <±100 µV DC. The nulling is automatically performed when the
receiver does not have an optical input. A typical OC-48 eye diagram for the detector output is
shown in Figure 2.
