| Brand Name : | INTEPON |
| Model Number : | optical circulator |
| Certification : | RoHs, ISO9001:2015 |
| Payment Terms : | T/T, Western Union |
| Supply Ability : | 1500~2000pcs per month |
Fiber optic circulator, 1520~1620nm, 3 ports, 1dB insertion loss, 35dB isolation.
The 1520~1620nm fiber circulator can be used to protect the signal source with high isolation.
From this point, you can treat it as an isolator but it doesn't equal to the isolator. Taking the number of the ports as an example, the isolator has one input and one output but the 3ports circulator has 2 input and 2 output. For this reason, the port 2 of the 3 ports circulator is the input and output, it means that you can input your signal from port 2 and you can also transmit the optical signal from port 2.When we talk the light path of the circulator, it like this, check the below info for more details about the working path.
Firstly, the signal inserts from port 1 and output port 3.
Secondly, the other signal will input port 2 and output port 3
We need to pay more attention to the port 3 because it can not be treated as an entry.

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.
