SIR WITH RESPECT I AM PRESENTLY PURSUING MTECH IN ELECTRONICS AND COMMUNICATION ( SPECIALIZATION:COMMUNICATION).Sir i am a new user of WDM PHASAR freeware and i am ablee to understand it properly. could you please provide me some tutorials or something helpful so that i could be to run it. thanking in anticipation.

Dear Sir,

In optisystem software various type of switches are present like optical, digital and WDM based.
if you need the switches for your project, you can check inside the component library for any type of switches.

Dear all,
can anyone tell me the present challenges faced by UDWDM PON technologies?
I have started working in this area but till now couldn’t find any good challenge…so kindly help me in this regard.

thank you

dear Alitsu,
are you working in UDWDM PON technologies? if it is so, I would like to know the present challenges faced by this technology as I too am working on it.please help me out in this regard

thank you

Hi fellas,
I had designed TWDM in optisystem 14. the system work fine but I have problem with the eye diagram.
eye diagram DS not so good compared with eye diagram US. I config twdm system with 8 olt – 8 onu agregate 80/80 gbps,
BW for DS US are 50 Ghz, power Tx 18, and power Rx 15.
My questions are, what should I measured the component so I can get a better eye diagram for DS. I attach picts of eye diagram DS and US.

Thank u for attentions.

Hi everyone. My name is Zulfikar. I’m student of bachelor’s degree in Telecomunication Engineering at Telkom University Indonesia. I’m also new to this forum. What I want to ask is, is it possible to build a WDM-PON system with bit rate 40Gbps and integrated with RoF? Actually I want to bring that topic for my final project. So, if anyone can help me here will be appreciated so much.
Thank you!

Hi everyone!
You can call me Maulana, I’m in senior year doing my final project about TWDM-PON using optisystem.
I want to make a TWDM simulation but my supervisor asked me to do more research about the OLT and ONU that they using it at NG-PON2 or TWDM-PON.
My question is does anyone can help me so I can getting information like a real OLT’s datasheet or ONU’s datasheet that they (huawei,alcatel,zte,or calix) use for NG-PON2 ? I was searched, and I got nothing because I can’t access the infromation at their website ex : calix.com .
Hope to get you reply guys.
Thank you .

Hi everyone.
Let me introduce my self, my name is Maulana.
I’m doing my final project about NG-PON2
How can I analyze about redundancy for TWDM-PON ?
Thanks. Hope u reply this

This is my design. please go through it and suggest how can i improve.

N*1 bidirectional splitter in wdm pon architecture

Can someone please tell me why is my design not showing the output. I think the problem is with the bidirectional splitter I have used. I need to implement it in order to work further in the field. Attaching it below. Regards.
My design has run after I have replaced the n*1 bidirectional splitter with wdm mux-demux in the design. Have not got the desired output yet +but better than nothing. Will somebody please tell me how to implement it properly and why has the bidirectional splitter not worked. Attaching the new work. Regards.

hello everybody
i desined a simple model for TWDM pon system, the model work good , but when i but the Bidirectional component like Bidirectional fiber or Bidirectional AWG , the signal disappear.
i attached my file if anyone can help me to run it please

I have tried uploading this file earlier too but for some reasons it did not upload. Attaching it below. Hope it uploads now successfully. Regards.

Please tell me why is my file not being uploaded.

I am uploading the image of my design.Please help me by guiding me.
