FAQ Section

Q1: What is the purpose of a fiber optic attenuator?
A1: It reduces optical signal strength to prevent overloading receivers or for test calibration.

Q2: Can I choose the exact attenuation value?
A2: Yes, we offer 1dB to 30dB values in 1dB increments.

Q3: What's the difference between UPC and APC?
A3: UPC has a flat polish, APC has an 8° angle for higher return loss. Choose based on application needs.

Q4: Is it suitable for OM3 multimode systems?
A4: Yes, OM3 color-coded attenuators are available.

Q5: Can I customize the housing color or print my logo?
A5: Yes, we support full OEM customization.

Q6: How accurate is the attenuation level?
A6: Each unit is tested to ±0.5dB accuracy.
