Product Details
C+L band optical circulator, 3 ports, 1.0dB insertion loss, 30dB isolation.
The C+L band 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.
