WARNINGS, CAUTIONS, AND GENERAL NOTES
Safety Considerations
When installing or using this product, observe all safety precautions during handling and operation.
Failure to comply with the following general safety precautions and with specific precautions described
elsewhere in this manual violates the safety standards of the design, manufacture, and intended use of
this product. Ortel assumes no liability for the customer's failure to comply with these precautions.
Calls attention to a procedure or practice, which if ignored, may result in damage to the system
or system component. Do not perform any procedure preceded by a CAUTION until described
conditions are fully understood and met.
Electrostatic Sensitivity
ESD = Electrostatic Sensitive Device
Observe electrostatic precautionary procedures.
Semiconductor laser transmitters and receivers provide highly reliable performance when operated in
conformity with their intended design. However, a semiconductor laser may be damaged by an
electrostatic charge inadvertently imposed by careless handling.
Static electricity can be conducted to the laser chip from the center pin of the RF input connector, and
through the DC connector pins. When unpacking and otherwise handling the transmitter, follow ESD
precautionary procedures including use of grounded wrist straps, grounded workbench surfaces, and
grounded floor mats.
Exposure to electrostatic charge is greatly reduced after the transmitter has been installed in an
operational circuit.
If You Need Help
If you need additional help in installing or using the system, need additional copies of this manual, or

DANGER
The Ortel laser products are used in optical fiber communications systems for radio frequency and
microwave frequency analog fiberoptic links. In normal operation, these systems are fully enclosed and fully
shielded by the hermetically sealed laser metal package. Laser bias current is limited by the internal control
circuitry. The transmitters are coupled to glass fiber and have 1300 nm optical output wavelength with
typically .5 to 7 mW output power depending on the model. The optical radiation is confined to the fiber
core. Under these conditions, there is no accessible laser emission and hence no hazard to safety or
health. Variations in the different models reflect the bandwidth, optical output, noise, and distortion of the
laser.
Since there is no human access to the laser output during system operation, no special operator precautions
are necessary when fiber is connected to the transmitter and receiver. During installation, service or
maintenance, the service technician is warned, however, to take precautions, which include not looking
directly into the fiber connector or the fiber, which is connected to the fiber connector before it is connected
to the fiberoptic receiver. The light emitted from the fiberoptic connector or any fiber connected to the
connector is invisible and may be harmful to the human eye. Use either an infrared viewer or fluorescent
screen for optical output verification. All handling precautions as outlined by the FDA and ANSI Z136.2 and
other authorities of class IIIb lasers must be observed.

Chapter 2 - Safety Precautions
2.1 ESD SENSITIVE
Semiconductor lasers and photodiodes are static sensitive devices, and products containing
them should be treated accordingly. Static electricity can be conducted to the laser chip from the
center pin of the RF input SMA connector, and through the DC connector pins. When unpacking
and handling the delay line, prior to install action, use ESD precautionary procedures such as
grounded wrist straps and grounded work mats.
After the delay line is installed in an operational circuit, these pins are protected from casual
contact and ESD sensitivity is greatly reduced.
2.2 POWER SUPPLY
A power supply is required to provide power to the laser, the photodiode and to the temperature
control circuits. Operating the delay line outside of its recommended power supply values may
cause damage to the product. Damage can occur to the laser if the delay line is operated with
one or more supply voltages set improperly. It is recommended that the supply voltages be
turned on simultaneously after the connections have been made to the 9-pin connector. For best
results, avoid connecting the 9-pin connector to the delay line housing while the power supply is
on (see Section 3.3 for connection instructions before applying power).
2.3 INPUT RF POWER
The laser diode can be overdriven and damaged by the application of excessive RF power.
Refer to the specific Product Specification Table for information about the maximum permissible
RF power to the delay line. Do not apply RF power with the delay line turned off.
2.4 GROUNDING
All power supplies should be connected to an earth ground.
2.5 STORAGE
Observe ESD precautions while storing the delay line (i.e., anti-static containers) and store away
from corrosive materials. Storage temperature: -40 to 85ºC.

Chapter 3 - Operation
THEORY OF OPERATION
The Model 5016 series fiberoptic delay line uses an Ortel high-speed laser module to generate an
intensity modulated optical signal at 1300 nm wavelength. The 5016 A/B/C/D uses a high performance
distributed feedback (DFB) laser with a built-in optical isolator. This signal is sent through a length of
singlemode optical fiber and received by a high-speed photodiode, which outputs the RF signal. For more
complete information on the operating principles of analog fiberoptic links, consult Ortel's RF/Microwave
Fiberoptic Link Design Guide.
3.1 EXTERNAL DISPLAYS AND CONTROLS
There are no external controls or adjustments. The laser current is preset at the factory to
provide optimum performance according to the specifications published in the data sheet and the
Product Specification Table.
3.1.1 LED DISPLAYS
There is one externally visible LED that provides information about the operating state of
the delay line. This LED is normally on. If it is off after applying dc power to the delay
line and waiting for a few seconds, recheck all power connections. If the condition
persists, consult with Ortel's Customer Service department.
POWER ON: This LED is normally ON, and indicates that +15 V is present at Pin #1 of
the dc 9-pin connector.
3.1.2 STATUS MONITORS
Three monitor voltages are available on the dc connector. They are designed to provide
information about the operating condition of internal optical power circuits for routine
operational maintenance.
PIN 6: Laser Photodiode Current Monitor. 1 V/mA, ±2% (1.0 MΩload). Provides a
buffered voltage proportional to the photodiode current.
PIN 7: Received Low optical Power. 1 V/mA, ±2% (1.0 MΩload). Provides a buffered
voltage proportional to the photodiode current.
PIN 8: Laser DC Current Monitor. 1 V/100 mA, ±2% (1.0 MΩload). Provides a buffered
voltage proportional to the laser dc current. Measuring and recording this
voltage provides a record of the laser current over time. The normal range is 0.3
to 0.75 V (30 to 75 mA).

Ortel, A Division of Emcore MAN-5016 Rev A
Series 5016

3.1.3 ALARM FUNCTIONS
The alarm is designed to interface with user-supplied circuits. The alarm is an open
collector output capable of sinking 20 mA when ON and withstanding 15 Vdc when OFF.
Normal operation of the alarm circuit is the OFF state. A suggested use of the alarm
circuit would be a series connection of an external LED, or a relay, from the system 15 V
supply through a 1 kΩresistor. Assuming negligible voltage drop through the LED or
relay, this would provide a 15 mA activation current when the alarm is active.
The alarm function and pin assignment is as follows.
PIN 9: Laser Temperature. This alarm is ON (sinks current) if the laser substrate
temperature is more than 2oC higher than the factory setpoint. The alarm is not
activated if the temperature is LOWER than the setpoint.
3.2 INTERNAL CONTROL CIRCUITS
The laser module contained in this delay line contains two sensing elements to provide feedback
on the operating conditions of the laser. They are, a monitor photodiode, which provides a
current proportional to the output power of the laser chip, and a thermistor, which provides
information about the temperature of the laser substrate. The entire substrate is mounted on a
Peltier Cooler (thermoelectric cooler), which can heat or cool the laser substrate as necessary to
maintain a constant operating temperature for the laser chip.
The 5000 series delay line contains two feedback control circuits, which use these sensing
elements to maintain stable operation.
3.2.1 OPTICAL POWER STABILIZATION
The optical power control circuit senses the current generated by the monitor photodiode
and compares the resulting voltage against a reference voltage, which is preset at the
factory. A feedback circuit drives a highly stabilized current source, which provides the
dc current for the laser operation. This mode of operation is known as "constant power".
As the laser ages, the control circuit will maintain the optical output power, as sensed by
the internal photodiode, constant by adjusting the laser current to compensate for
changes in chip operating temperature, threshold current, and quantum efficiency. The
power control circuit will not compensate for changes in the laser/fiber coupling
efficiency.
In addition to the dc current supply circuit; there are two additional circuits in the optical
power control circuit. A "slow start" circuit operates when the delay line is switched on.
This circuit increases the laser current over 3 seconds from zero to its operating value.
This eliminates transients and which could damage the laser. A current limiter, preset at
the factory, establishes a maximum value for the laser current. Thus, a failure of the
monitor photodiode will not result in uncontrolled laser current values, which would
destroy the laser.

Ortel, A Division of Emcore MAN-5016 Rev A
Series 5016
15
3.2.2 TEMPERATURE STABILIZATION
The temperature control circuit senses the thermistor resistance in the laser module and
compares it against a variable reference, which is preset at the factory. The error voltage
drives an integrator, which supplies current to the T/E cooler (TEC). The current source
is bipolar, so heating and cooling functions are provided to the TEC.
As with the power control circuit, a current limiter prevents the TEC and laser from
damage due to excessive heating or cooling functions should the thermistor fail.

Chapter 4 - Installation and Setup Procedures
4.1 UNPACKING AND VISUAL INSPECTION
The product described herein was inspected before shipment and found to be free of mechanical
and electrical defects. Observe ESD precautions while handling the delay line. Unpack and
examine the product for any damage due to shipping. Keep all packing materials until you are
satisfied that the product works according to specifications. Verify that the pins and connectors
are free from obvious shipping or handling damage. If damage is discovered, file a claim with the
carrier immediately. Notify the Ortel Sales Department as soon as possible.
4.2 OPERATING CONDITIONS
This product is designed and tested to withstand harsh environmental operating and storage
conditions. The basic design and manufacturing processes have been subjected to rigorous
product qualification tests of temperature cycling, mechanical shock, and vibration. Every
product is warranted to operate within specification over the temperature range from -20 to 65ºC,
and to withstand storage temperatures from -40 to 85ºC without degradation.
4.3 CONNECTION INSTRUCTIONS
To operate the 5016 at room temperature in a laboratory setting, it can be placed on a convenient
flat surface without any particular concern for a good heatsink. In a field-operating environment,
to obtain reliable operation over the full temperature range, make the fiberoptic connections
before applying power to the 5016.
4.3.1 ELECTRICAL CONNECTION
Observe the following procedures while making electrical connection to the delay line.
4.3.1.1 DC CONNECTION
Connect the transmitter to the required dc voltages using a standard 9-pin DSUB
connector. Do not solder wires directly to the pins of the dc connector. The
delay line contains internal regulator and transient suppression circuits. Most
high quality power supplies will provide excellent results. For best results, make
the dc connection to the transmitter before switching on the supply.
When turning the transmitter on, there is a "slow start" circuit that introduces a
2-3 second delay in the turn on. When the LED's are all lit, the 5016 is ready to
use.

Ortel, A Division of Emcore MAN-5016 Rev A
Series 5016
17
4.3.1.2 RF CONNECTION
Apply RF power only after DC power has been applied. Connect the RF signal
source to the SMA input connector. Absolute maximum signal level shall not
exceed 100 mW.
CAUTION: Do not apply excessive torque to the SMA connector. The use of
standard wrenches can lead to a damaged connector. Use 7-9 inch
pounds of torque. The use of a torque wrench is strongly
recommended.
The input impedance of the delay line is 50 ohms. Use signal
sources with the same characteristic impedance. Consult the
Product Specification Table for the maximum input signal level. Do
not exceed this level to avoid damaging the laser diode.
