. Optical isolator, 3.0x25mm, 1550nm, 46dB isolation, 0.6dB insertion loss.
The isolator is an important fiber device in the telecommunication system. It can protect the light source with Faraday rotator. You can see that the device is like the optical circulator, they are based on the GRANOPT's faraday rotator. The circulator has three ports but the isolator has only two ports, the circulator can be treated as an isolator because the circulator is also a reciprocal device.
In order to provide our customer better service, we developed the mini size isolator.

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?
A: You place an order first. Then we will send you PI. After you settle the payment by TT or the Western Union. We will arrange production for you.
Q: What is your normal production lead time for a first order and then for repeat orders?
A: It depends on the product you need. For example, if you purchased a 1550nm fiber circulator for your first order, and then you look for it again, but we will check the material of it and tell you the delivery time.
Q: Do you have warranty policy?
A: Yes, we have. We provide 12 months maintenance warranty.
