splitter or fork…

HELLO JYOTI..
As far as your query is concerned well there is a difference between using fork and splitter in your design…if you want your signal to be duplicated without any loss then its better to use fork…and in other case the term split itself suggests that the signal is splitted…
it splits the signal power and also losses are associated when using a splitter..
I hope u understand the difference.. hope it helps you..
Thanks & regards

Hello jyoti,
As mentioned by fayiqa the major difference lies in the application. It depends on the system design. I am posting a link where the topic has been already discussed and i hope you get an idea about the usage of two components. Please refer to this link for further information. I hope you find it helpful.

Physical importance of Fork component

Hi jyoti raina..

That is a good question you asked.
Well as already mentioned, a fork replicates a signal, and I think it is used for making our simulation tests easier. Suppose you want to check results at two different types of receivers, you don’t need two separate simulations. Instead, you could use a fork.. and give the two signals to two different receivers and analyse results in just one simulation.

On the other hand, a splitter, as the name suggest, divides power /signal into many .

I hope I am clear.

Hello Jyoti Raina,
I think you are referring to balance photo detector. so for this you can use a X-Coupler at the input side of the photodetectors. I have attached herewith a snapshot fo the same. Thanking you..

Hi Dhiman..

Yes, that could also be one aspect of using it.
Also, could you please try uploading your attachments again? Those are not available in your comment.

HELLO DHIMAN..
Thanks for sharing the snapshots…
But here i want to ask u that Does coupler serve us the same way that fork does..??
From theoretical aspects, a coupler has two output ports, one used for transmitted power and the other for coupled power although some is reflected back as reflected power so there is possibly going to be losses associated with the usage of coupler which may deteriorate the results…
Thanks & regards

Hello All

As far as the definition of splitter and fork is concerned its just that splitter splits the power while as the fork duplicate the incoming power with same power in the outputs. But dhiman i also wanna ask this that dows coupler perform in a similar way as that of a fork . As of now we have know a coupler as to combine the power in one of the outputs for the inputs being from transmitter and the combining signal.

hii jyoti… as discuss by all fork is used for replicating the signal where as splliter is to divide the power level .. for example if you are using a 1:2 splitter you will get a power/2 at each output port of the the spillter as compared to input ..where is in fork u will get same power level .. one for thing i want to add that splitter is generally used in PON(Passive Optical Network)… hope you are getting the point

Hi all,
As we know Firk Copies the input signal into different output signals without any loss. This tool allows you to duplicate component output ports.
Splitter component splits evenly the signal input power to N output ports.
The s-parameters for the splitter are:

S = {10Log(1/N)-Alpha}<0 degree
Where  is the parameter insertion loss (dB), N is the number of output ports and i is
the output port index.

Hi Jyoti Raina

you are welcome. regarding your query about the coupler. dear i don’t know your circuit as such so i don’t know weather u require coupler or fork or splitter. it depends on the requirement in ur design.

Hi jyoti,
You are welcome.
We couldnot use s-parameters in optisystem software, i have just suggest you the difference between splitter and fork.
Sometimes we need theoretical and mathematical theory for explanation in publishing research works. So, i have tried to explain that.
thank you for consideration and highlighting the topics.

Hi jyoti raina

You are most welcome. Feel free to ask for help in this forum. It is meant for that purpose only.

Hello friends
As where as i concerned to the above posted matter. i always saw that whenever we combine the data like in DWDM or SCM we use the concept of power combiner and power splitter at receiver whereas fork is always used to analysis for testing reason like what signal the component is actual generating so that it could be analysed at the receiver whether the sent signal is matching with the transmitter signal(analysed suing fork) or not. thank you

You are most welcome Jyoti Raina Ma’m.
Thank you for appreciation and conscent, i will try to suggest as per my ability.

KK Jyoti,
It’s need to worry about.
These all discussions will help you to learn and understand optisyetem quickly and efficiently.
Thanks to “https://optiwave.com/forums&#8221; for such a wonderful platform for beginners as well as experts to learn a new topic as well as get command on previous topics.

Hi Jyoti Raina,

Indeed this forum is a great learning curve for all of us…. Cheers optiwave team…

hi joyti raina,

splitter —> technically speaking divides the power of input equally at the output.

i.e : if 10mW input is given to 1:4 splitter , the output power will be 2.5 mW (10mW/4)each
fork —> technically speaking replicate es the power of input to each of the output.

i.e : if 10mW input is given to 1:4 fork , the output power will be 10 mW each.

thus you need to use them as per the design needs

with regards

Hi Jyoti Raina,

Infact a very valid point put forward by Asif Bashir with a very good explanation and a nice example… I completely agree that you need to use them as per your design needs…

hi all,

i hope the dision ended with that fork cretes copies of the input and the splitter divides the input equally

regards

Well Asif..it had to end on that ; as you had rightly mentioned it in the first place. (y)
