Getting Started
Installation
CAUTION. The output of the Optical Receiver System and the input of the
sampling head are subject to damage from electrostatic discharge (ESD). To
prevent damage from ESD, take the following precautions:
Always wear an anti-static wrist strap when handling a static sensitive
instrument.
Keep the 50 W termination in place when moving or storing the instrument.
Remove the termination only to connect a cable.
Discharge the inner conductor of a loose, unterminated cable before connecting
it to the instrument.
NOTE. To guarantee compliance with FC, GBE, or OC-48 boundary limits, you
must connect the ORS20 Optical Receiver System to the input of an SD-22
sampling head using the 015-0560-00 cable provided. The ORS20 Optical
Receiver System is designed for the electrical characteristics of the cable and the
particular frequency response and low noise of the SD-22. Test temperatures
must be 20 to 35°C.
Use the following procedure to connect the Optical Receiver System to a
Tektronix 11801/CSA803 sampling oscilloscope:
1. Switch off the instruments.
2. Follow anti-static precautions and connect the output of the Optical Receiver
System to the input of the SD-22 sampling head with the 015-0560-00 cable
provided:
a. Align the SMA connectors carefully.
b. Use light, finger pressure to turn the nut. Do not turn the cable.
c. Tighten the nut lightly with a wrench. For best repeatability and to
prolong the life of SMA connectors, use a torque wrench and tighten
the connection to the range of 7 to 10 lb-in (79 to 112 N-cm).
3. Connect an optical source, such as a Tektronix OIG 501/502 Optical Impulse
Generator or CTS 710/750 SONET Test Set, with an input cable to the
optical input on the ORS20 Optical Receiver System.
4. Switch on the instruments.

ORS20 Instruction Manual
Operating Basics
Handling
Figure 1 on page 1 shows the front panel of the ORS20 Optical Receiver System.
The ORS20 Optical Receiver System has an SC/PC receptacle (FC/PC opt. 01)
for optical signal input and a precision 3.5 mm connector for electrical signal
output.
Handle the ORS20 Optical Receiver System carefully at all times.
CAUTION. To avoid damaging the ORS20 Optical Receiver System, take the
following precautions:
Do not drop the Optical Receiver System since damage and misalignment of the
photodiode optical assembly can result. Store the Optical Receiver System in a
secure location when not in use.
Replace the protective caps on the input and output connectors when the Optical
Receiver System is not in use.
WARNING. Do not look directly into any optical output port. Laser light can be
harmful to your eyes.
Cleaning Optical Connectors
Small dust particles and oils can easily contaminate optical connectors and
reduce or block the signal. Take care to preserve the integrity of your connectors
by keeping them free of contamination.
CAUTION. To prevent loss of optical power or damage to the optical connectors,
keep the connectors clean at all times.
When cleaning the connectors with a swab, use gentle circular motions. Use only
high quality cleaning supplies that are non-abrasive and leave no residue.
To reduce the need for cleaning, immediately replace protective caps on the
optical connectors when not in use.
ORS20 Instruction Manual

Operating Basics
Equipment Required
Procedure
Use the following items to clean the optical connectors:
H clean compressed air
H fiber-optic cleaning swabs
H isopropyl alcohol
To clean the optical connectors, follow these steps:
1. Hold the can of compressed air upright and spray the can into the air to purge
any propellant.
2. Spray the clean compressed air on the connectors to remove any loose
particles or moisture.
3. Moisten a clean optical swab with isopropyl alcohol then lightly swab the
surfaces of the connectors.
4. Spray the clean compressed air on the connectors again to remove any loose
particles or isopropyl alcohol.
NOTE. Cleaning kits for optical connectors are available from several suppliers.
Connecting Signals
Attach the fiber optic cable with an SC or FC connector to the SC or FC input
receptacle as follows:
1. Carefully align the keyway on the receptacle with the key on the connector.
2. For the FC/PC connector (Opt. 01), tighten the nut lightly with finger
pressure only.
The input of the ORS20 Optical Receiver System can couple to optical fibers
with a core diameter of up to 62.5 mm. Alternate types can be coupled by use of
fiber jumper cables and hybrid fiber connectors. (Refer to Optional accessories
on page 34.)
CAUTION. To maintain the high performance (low return loss) of the reference
receiver, connect an adapter and cable between the input of the reference
receiver and the device under test. When you make connections to other devices,
leave the adapter and cable in place to protect the optical connector of the
reference receiver from wear.
6
ORS20 Instruction Manual
If you connect fiber cores larger than 62.5 mm, the reference receiver may still
couple light, but the mismatch in core diameter will cause lower conversion gain
and high insertion loss.
NOTE. Fiber cores smaller than 62.5 mm will work properly. For example,
single-mode fiber input is compatible with the ORS20 Optical Receiver System.
Attenuating Optical Signals
When using the ORS20 Optical Receiver System as a reference receiver, it may
be necessary to attenuate the optical signals.
CAUTION. To avoid damaging the optical input of the ORS20 Optical Receiver
System , attenuate optical signals to less than 5 mW average power or 10 mW
peak power.
Operating Basics
For linearity and measurement accuracy, attenuate the peak-to-peak swing of
signal to within the specified performance of ≤200 mV p-p voltage swing at the
output. The optical swing this corresponds to depends on the wavelength of the
signal being input and the conversion gain of the ORS20 Optical Receiver
System at that wavelength.
Example:
1. You want to look at an 1310 nm, OC-48 eye-pattern signal whose average
power (un-attenuated) is about +2 dBm. The average optical power of the
+2 dBm signal is equal to 1584 mW.
2. For optical signals with a 50% duty cycle, the average power is
approximately one half of the peak-to-peak swing for high extinction ratio
signals. This means that the peak-to-peak value of the optical signal is
approximately
2 x 1584 mW = 3168 mW p-p
3. If the conversion gain of the ORS20 Optical Receiver System is 0.90 V/mW,
then this level of optical input would correspond to a voltage output swing of
3168 mW p-p
0.90V/1000 mW = 2534 mV p-p (but the system would
.
typically saturate at 800 mV p-p).
4. To lower the signal to within the 200 mV p-p linear output range, the signal
must be attenuated by 2534 mV / 200 mV = 12.67; this ratio is equal to
about 11 dB of optical attenuation.
ORS20 Instruction Manual
7
Operating Basics
TEKPROBE Adapter
To attenuate the optical signal to the proper level, use a Tektronix OA5022
Optical Attenuator. (If single-mode fiber is used to the ORS20 Optical Receiver
System input, use a Tektronix OA5002 Optical Attenuator.)
WARNING. Do not look directly into the optical output port. Laser light can be
harmful to your eyes.
The TEKPROBE adapter allows you to use the ORS20 Optical Receiver System
with any TEKPROBE-compatible oscilloscope. When the ORS20 Optical
Receiver System is connected to a TDS Series DSO, the units displayed will
automatically be converted to watts, and the vertical scaling will automatically
be adjusted for the conversion gain at 850 nm.

Compression: this term is referring to the additional frequency response loss
typically experienced when large signal swings are present at the output (as
opposed to 200 mV p–p or smaller swings). These losses are in addition to the
frequency response rolloff characteristics already inherent in the system for small
signal output swings.
The ORS20 Optical Receiver System is an amplified O/E converter, and as such
the internal active amplifier has output drive limitations. The maximum input
optical peak-to-peak power can be estimated by using the known V/W conversion gain at the particular wavelength of interest.

Performance Verification
1. Attach the output of the ORS20 to the voltmeter inputs with a 50 W
termination and BNC-to-banana adapter.
2. Install the optical dust cover on the input of the ORS20.
3. Check that output voltage is ≤ ± 1 mV. Record the result on the test record.
NOTE. Make sure that the optical connector ends of both the fiber from the
optical attenuator output and the input fiber for the ORS20 under test are well
cleaned before performing this step. See the cleaning instructions on page 5.
1. Connect the 780 nm laser source to the multi-mode attenuator input.
NOTE. The longer wavelengths of 1310 nm and especially 1550 nm are sensitive
to loss in fiber due to bending of the fiber. The fiber bend radius of the ORS20
fiber input should lay with >1.5 inch bend radius along the fiber’s entire length.
Although this precaution must be maintained throughout the entire performance
verification procedure, it is especially important for this step in order to
accurately measure the DC conversion gain of the ORS20.
2. Connect the optical attenuator output to the optical power meter using
multi-mode optical cable with FC connectors. Use the appropriate optical
power meter sensing head with calibrated measurement for a wavelength
span including 780 nm, 850 nm, 1310 nm, and 1550 nm. Verify the optical
power meter wavelength setting and the optical attenuator setting is at 780
nm. Enable the optical output.
3. Adjust the attenuator or the optical source so that the power meter reads
200mW.
4. Move the FC fiber end (the one now adjusted to 200 mW average power)
from the optical power meter and connect it to the ORS20 input under test.
5. Attach a voltmeter with 50 W termination to the ORS20 output.
6. Record the voltmeter reading. The 780 nm Conversion Gain in units of
V/mW is

9. Adjust the optical attenuator until the voltmeter reading is the same as in
step 6 above, ± 1%.
10. Without moving the optical attenuator from the position in the previous step,
disconnect the output fiber of the optical attenuator from the input of the
ORS20 and insert the optical attenuator output into the optical power meter.

and the ORS20 input.
14. Adjust the optical attenuator until the voltmeter reading is the same as in
step 11 above, ± 1%.
15. Without moving the optical attenuator from the position in the previous step,

Performance Verification
Bandwidth/Frequency Response (Using OIG501/502)
NOTE. The performance of every component of your setup has an affect on the
overall performance of your system. This procedure allows you to characterize
and plot the performance of your particular setup which includes the channel of
your sampling oscilloscope, the sampling head, the ORS20 O/E Converter, and
the electrical cable.
To optimize performance, make sure that all connections are clean and secure
and that all components of the system are in good condition. Optical fiber, in
particular, can gradually degrade the system performance as it is repeatedly
flexed over time.
1. Connect the setup as shown in Figure 8. Note that this requires an SD-22
sampling head.

3. Adjust the attenuation of the OIG until the ORS20 produces more than
30 mV p-p, but less than 80 mV p-p impulse response.

4. Locate and center the first impulse (after time zero) on the oscilloscope
display. (For a 10 MHz repetition rate, the impulse should occur at about
100 ns. You may experience signal jitter if you try to display a signal that is
not the first impulse and is late in relation to time zero.)
ORS20 Instruction Manual
Performance Verification
Finish setting the oscilloscope controls as follows:
5. Set the horizontal time to 100 ps/div, set the vertical controls for maximum
screen usage, and set the signal averaging to 64 times and 2048 points.
6. Using a controller attached to the scope via GPIB (for example, a PC, MAC,
workstation, etc.) download the waveform.
7. Using the available controller software (for example, Labview, etc.) perform
an FFT (Fast Fourier Transform) on the waveform; this transforms the
time-domain (1024-point) impulse response to a scalar frequency response.
8. Normalize the FFT result such that DC or low frequency is 0 dB.
9. Plot the frequency response.
10. Check that the frequency response from DC to 2.3 GHz is greater than or
equal to –6 dB, where dB = 20log (V
log/Vdc
) for electrical power into 50 W.
11. Check that the frequency response from DC to 4.98 GHz is within the
OC–48 boundary limits defined in ITU–T G.957.
12. Set the ORS20 to 1063 RR mode by pushing the mode button until the LED
next to REFERENCE RECEIVER 1063 Mb/s is lit.
13. Repeat steps 5 to 11 above.
14. Check that the frequency response from DC to 2.126 GHz is within the Fiber
Channel boundary limits defined in ANSI FC–PH.
15. Set the ORS20 to 1250 RR mode by pushing the mode button until the LED
next to REFERENCE RECEIVER 1250 Mb/s is lit.
16. Repeat steps 5 to 11 above.
17. Check that the frequency response from DC to 2.5 GHz is within the GBE
boundary limits defined in IEEE P802.3Z.
This completes the performance verification procedure.

Bandwidth/Frequency Response (Using Calmar FPL-01)
NOTE. The performance of every component of your setup has an affect on the
overall performance of your system. This procedure allows you to characterize
and plot the performance of your particular setup which includes the channel of
your sampling oscilloscope, the sampling head, the ORS20 O/E Converter, and
the electrical cable.
To optimize performance, make sure that all connections are clean and secure
and that all components of the system are in good condition. Optical fiber, in
particular, can gradually degrade the system performance as it is repeatedly
flexed over time.
1. Connect the output of the optical impulse generator to the 10 dB inline
attenuator, 90/10 splitter, and optical attenuators as shown in Figure 9. Start
with about 30 dB of attenuation on both variable attenuators.
NOTE. To avoid dispersing the narrow optical impulse signal, keep all fiber
lengths as short as possible. Lengths that are 2 to 3 meters long are acceptable.
2. Before you connect the attenuator to the ORR24, you must adjust the signal
on the 10% path to the proper level. To measure the output of the attenuator
on the 10% path, you can use another oscilloscope or you can use an optical
power meter.
a. If you are using another oscilloscope to display the trigger signal, adjust
the attenuation of the 10% path until the ORR24 produces more than
200 mV p-p, but less than 1 V p-p impulse response.
b. If you are using an optical power meter, connect the output of the optical
attenuator on the 10% path to the optical power meter. With a pulse
width of 500 fs and a frequency of 10 MHz, adjust the optical
attenuator until the power meter reads about 1 mW average power.
3. Finish connecting the setup as shown in Figure 9. Note that this requires an
SD-22 sampling head.
