There are very many passive components involved in fiber optical networks and an optical circulator is among the top options. These components help in signal delivery without any failure thus remain to be very important. When used, the optical circulator will direct the signals between different ports but maintaining a single direction. There will be no chances of the signal going in a different direction that was not intended.
Two-way situations apply
However, that does not make it a one-direction device only. There are rare situations where you can have the circulator used in a two-way situation. When there is an optical signal sent by the circulator in two different directions, the fiber is usually one. You will have the circulator fixed on the two ends of the fiber and will function by adding a signal in one end while removing from the opposite end.
Whenever you are choosing a Polarization Maintaining Optical Circulator to use, there are very many things that must be put into serious consideration. That will be the benchmark on which your choices will be based upon. Features must be one of the things that you look out for in an ideal optical circulator. The good thing is that such a circulator comes loaded with more features to make your experience remarkable.
Consider different applications
The circulator comes with two main high-power options to choose from. You can go for either 1550nm or 1064nm depending on your needs. The other standout features for Polarization Maintaining Optical Circulator include epoxy-free optical path and compact inline package. There are additional features that as well make the circulator a unique choice compared to other alternatives available.
The other thing to look at includes applications which play a key role in the functioning of an optical circulator. Main applications that you should pay attention to are bidirectional pumping, fiber sensors, add-drop multiplexing, bidirectional signal transmission systems as well as coupling inline chromatic dispersion compensation devices.
With these applications, you are sure that your circulator will give out an optimal performance. You can have a Polarization Maintaining Optical Circulator used in multiple optical settings thus it will offer you limitless options. That is because they are unidirectional and non-reciprocating while their availability as three-port makes the circulator even more suitable. Do you know that it’s possible to use optical circulators in communication systems that are more advanced? Well, that is yet another of their biggest advantage over other types of circulators.
Get optimal performance
That is made possible by the fact that optical circulators come with a very small insertion loss while their isolation levels are very high. When used in advanced systems of communication, the circulators will come as any of the common applications. The result you get from using Polarization Maintaining Optical Circulator will depend largely on how you have chosen to use it. If you make your decision well, the result will be good but if not then you will get a different result. It will all depend on your choices.
