Motor Driven Variable Attenuator Questionnaire
for choosing OZ Optics. In order to help you choose the best components for your system, we would appreciate it if you could answer the following questions. If you do not know what to enter, write DON'T KNOW beside the question. We will then recommend an option. If you need assistance filling out the form, you are welcome to contact your nearest distributor or our sales office where a sales representative will be happy to assist.
To process your information as quickly as possible, please ensure that the fields marked in
are completed before submitting your request. If this data is not entered we will be unable to respond to your request.

Part A : Attenuator Information
Complete this section to provide us information about the attenuator
Wavelength in operation, in nm:
Is your laser sensitive to Back Reflection?
(see note 1)
If Yes, what is your requested maximum return loss (in dB)?
What is the minimum acceptable loss?
< 1 dB ,
< 2 dB , Other
What is the maximum allowable response time for a 3dB attenuation change?
Not important ,
What resolution do you require?
What accuracy do you require?
dB over the range of 0 to
What supply voltage is available for driving the attenuator? (OEM version only)
What is the maximum attenuation required for your application?
What kind of electronics interface would you like?
User supplies all motor drive electronics and microcontroller. Controller will be supplied by user.
b) Communicate via:
Answer questions 11 through 12 ONLY if you require an intelligent, calibrated version:
If the interface is SPI: what is the idle state of the clock ?
If the interface is SPI: on what edge of the clock does the data change?
If the interface is I²C: what 7-bit address should the unit respond to?
Part B : Fiber Optic Cable Information
What is the fiber type required:
(See note 2)
Multimode (MM) Step index,
Multimode (MM) graded index,
Polarization Maintaining (PM)
What is the fiber Core/Cladding diameter in microns?
What is the fiber Numerical Aperture (Sine of acceptance angle)?
What is the fiver length required, in meter?
What is the cable type?
0.25 mm O.D. acrylate jacketing only,
0.40 mm O.D. acrylate jacketing only,
0.9 mm O.D. tight nylon jacketing,
0.9 mm O.D. hytrel loose tubing,
3.0 mm O.D. kevlar reinforced cable,
3.0 mm O.D. armored cable,
5.0 mm O.D. armored cable,
What type of connectors do you want at the ends of the cable?
NTT-FC (Flat Endface),
Cylindrical 1.8 mm O.D. ferrule,
For polarization maintaining connectors only, do you want the slow axis of the PM fiber:
Aligned and locked in line with the connector key,
Unlocked and rotatable
Note: If the connectors are not locked, the customer must rotate the fiber until the polarization axis is aligned with a second PM fiber.
Part C : Other requirements:
Please provide a block diagram of your system needs. Do you have any special requirements other than the ones listed above? (For example, a fused splitter, monitor photodiode, etc.) If so, please describe them in the space provided.
