FAQ
Q: What is a fiber fixed attenuator used for?
A: Fixed optical attenuator reduces excessive optical power to avoid receiver saturation, used for network power balance and fiber test calibration.
Q: What connector types do you supply?
A: SC, LC, FC, both PC (UPC) and APC polishing are available.
Q: Can I get custom dB values?
A: Yes, custom attenuation values are acceptable for bulk order.
Q: What is the return loss of OAT-HF?
A: Return loss ≥50dB, high return loss design for stable high-speed optical links.
