Please Solve the problem….

That means, each ONU is accessing only 10 GBPS than how average bandwidth per ONU is by using 4 transmitters??

[Amit GargParticipant]

Dear Alistu
Suppose we are using 4 transmitters (4 channels) each transmitting at bit rate of 10GBPS after multiplexing and passing through fiber cable and combined signal is passed through 1×4 power splitter as shown in attached file. Now each ONU is receiving 40 GBPS (all channels). My question is that how an ONU will access the 40GBPS while it is tuned on a single wavelength (10 GBPS)??

Dear Alistu
I agreed with you and I was also thinking like you. But I am in doubt that if power splitter is not splitting the bit rate than each ONU will receive the bit rate of 10 GBPS. In below attached file (table) how average bandwidth is divided to all users. I am little bit in confuse about the the relation between BIT RATE and BANDWIDTH. please explain it also.

thanks in advance.

Dear Alistu
the document attached by you is showing an error ” failed to load the documents” i am having the 13.0 version of optisystem. so plz upload the which is compatible with it.

Dear Alistu
I am also facing the same problem of receiver sensitivity if APD and PIN. in many papers and books. I have studied that sensitivity of APD is better then PIN. plz give us some more standard reference paper on which we can rely.

Hii, I am attaching one file where you can see the details. some graphs are are plotted on page 4. however attached paper is implemented by using OPNET. but I want to know weather is it possible to vary the traffic load.

I have tried by taking attenuation data type from file (not constant) but I am getting the same result.
can you please send me the some program me file (.OSD) that gives result (something similar )to the curve as given attached file

Hi Jaffar Emad Kadum,

I have studied in many research papers that the power penalty due to 20 km optical fiber is approximately ranges from 0.5dB to 1.5 dB.
but theoretically if we calculate the power losses in 20 km fiber is 4 dB (0.2dB/km*20 km) . then how it is possible ???
