Add Component Vs Combiner Vs Criculator

hi atul sharma…
as for as these three devices are concerned you can go through the lesson 7 of the optical tutorials for the basic difference between them.i am also attaching the link for your reference. hope it will help.

Lesson 7: Optical Amplifiers — Designing Optical Fiber Amplifiers and Fiber Lasers

As for as optical circulator is concerned it is a component that can be used to separate optical power that travels in opposite directions in one single fiber.
with regards.

Hello Atul Sharma,
As far as your query is concerned, it is a very valid query. Here i would like to mention that usually power combiner is used to combine power levels of the signals may be one two or n number of signals. It also depends on the system applications where and what for you are using it. Generally it is for combining of two or more signals leaving out power perspective. And as far as Add module is concerned, it is used to add another wavelength to the existing wavelength. In optisystem particularly , it has only two inputs. But generally speaking , it can very well serve you as a combiner ( not sure about power levels but it will combine your signal to existing signals ). I hope it is helpful.

Sorry i missed on the circulator part. Its functionality is similar to both of the afore mentioned components to some extent. I dont know the MAJOR difference between the three but i feel all can serve you in similar way off adding signals to existing signals. You can think of circulator as an adder too. As far as i am concerned, i fell add module and circulator have almost similar functions but somehow it depends on your system implementation and how you are using both in your system design. I hope it is helpful.

hi atul sharma,
combiner…..combines two optical input signals.
Optical circulator. You can control insertion loss, return loss, and isolation.
WDM ADD.Adds a WDM channel and a WDM signal.

for the technical background of each of the coomponent , i suggest you to go through the component help in the optisytem….

Ferrite isolators and circulators play a fundamental and valuable role in RF systems. They are passive, ferrite devices that act as traffic conductors for RF energy in a system, routing signals wherever a system designer needs them to go. Their ability to behave nonreciprocally
(non reversible, allowing energy to pass in only one direction through the device) when RF energy is applied to them is very important for a number of applications.When selecting an isolator and/or circulator, it is important to understand some common electrical specifications that tells how well it is capable of performing the application. The three basic specifications for isolators and circulators are insertion
loss, VSWR, and isolation.

well umer syed.,,

i think you are taking the discussion to the different level…as you are mentioning the theoretical aspects of circulators and isolators related to microwave or electromagnetics…. despsitre the basic prinple remains the same… however we can not paint every thing with the same brush.

Hi Atul Sharma,

The compents combiner,optical circulator and WDM ADD are used for performing different functions… It has already been very well explained by aasif the uses of these three components in the previous post…

Hi Atul Sharma,

Hope your query gets solved… And you are welcome…

Hi Atul Sharma,

I agree with your point of view that in theoretical basis we assume that the signal transmitted (with a definite bandwidth) has same transmission characteristics but In practical cases… You have mentioned it rightly that dispersion may be defined as the pulse broadening due to multi-path propagation…Thanks for such valuable information

hi atul sharma,
greetings..
i beleive that when there is problem in the understanding the component for me , i use the component help of optisytem…it is most useful…there may certain confusion still then you can discuss on the forum…

any ways i thing after this discussion you will have come to some conclusive remarks regarding your query..

with regards

Hi Atul,
Do you refer WDM add component as ADD component. AS WDM add Adds a WDM channel and a WDM signal.
Where as power Combiner combines evenly numberof inputs signals into a single output port.

Hello aabid baba,

Very nice information about the power combiner and a circulator… hope it helps Atul sharma to get his query resolved..

HELLO ATUL SHARMA..

In my opinion you can easily replace a power combiner with a circulator but i think there maybe difference in results though because using a circulator does affect your results…
Normally i have seen the circulator for adding and dropping wavelengths and in that process the results do get affected and moreover it you check the power levels after the circulator you will find the power level drops just in case of the WDM Mux..Still you can cross check by using it in place of power combiner and check for the results..

Thanks & regards

Hello atul Sharma,
I agree with fayiqa that we can easily replace a power combiner with a circulator but i think there maybe difference in results though because using a circulator does affect your results. Normally it is true that the circulator is used for adding and dropping wavelengths and in that process the results do get affected and moreover it you check the power levels after the circulator you will find the power level drops just in case of the WDM Mux. fayiqa has suggested you the right thing.

Thanks Atul.
