Fiber attenuator, 850nm, multi mode fiber, 26x18x8mm, 1~60dB attenuation.
The attenuator is based on collimator with the screw by hand which can attenuate the light in the optical path. It's widely used for protecting the network system.
Features
Structure: 1x1 port
Insertion loss : ≤ 1.0dB
Max attenuation: 60dB
High return loss: return loss ≥50dB for APC connector type
Applications
Protecting the light source
Optical amplifier
Optical transmission system

Q&A:
Q: What's your Payment terms?
A: We accept TT & Western Union for payment.
Q: How to order a sample?
A: You can contact us directly and tell us your requirements on any of our products.
Q: Could you print our company logo or design on the products?
A: Yes, we can accept your need but we will share the charge with you.
Q: If we decide to move forward with our order what is the next step?
