Hi, I need a simulation software that can simulate and show me the output signal versus time and show output noise and phase noise with complex components such as photonoc (mzm, laser, optical fiber) and transistor , mixer and .... thanks
Hi All, I'm looking for a competitor of PPM Test optical Link model Sentinel 3. It's a high performance transmission systems designed for test and measurement. Transmission of RF or DC over optical fiber to enables immunity to electrical interference ( ). Please, if you know some manufacturer or repr
Hello, Am doing a project on "LOW COST MIMO ENABLED RADIO OVER fiber SYSTEM FOR MULTISERVICE DAS USING DOUBLE SIDEBAND FREQUENCY TRANSLATION" Kindly help me in generating LTE MIMO signals for transmission across the optical fiber. Here am using OPTISYSTEM 7 software and trying to generate MIMO signals using MATLAB. Please help..
The variable of Splitting ratio is the most prominent advantage of FBT splitter(Fused Biconical Splitter) . For example, In the case of the number of users and the transmission distance is inconsistent,we need to be assigned to different optical power line,in this case, the devices require different splitting ratio.And because the PLC spli

Why can't we use optical fiber as a bi-directional channel.
Yes, optical fiber connectors have their own designations for return loss, the (inverse) optical correspondent to electrical reflection, resp. adaption (e.g. by a 50Ω resistor in a 50Ω transmission line) High return loss means low amounts of reflection at the interface ... see [URL="https://en.wikipe
What is the difference between "at intermediate points with in a cable where two fibers are joined and at intermediate points in a link where two cables are connected"
Is there any links to tutorials, projects, schematics, kits... that you know of for a LED based voice intercom/transceiver over the air ? (not laser, not fiber optics)
I want to equalize 2x2 MIMO system, the system uses two optical fiber as a communication channel, the fiber length divided into segments and at the end of each segment coupling between two fibers occurs that needed to be equalized using LMS algorithm I use this code and want to check is it the correct 2x2 LMS equalizer or (...)
There are two avenues you can look at. First, micro sized antennas that receive optical frequencies. Second, a RF antenna that modulates a signal in an optical fiber for remoting the antenna far from electronics or a power source.
there are many parts of the optical communication,except the WDM which is just a part of the fiber optic network u mention above.there are fiber optic transceiver,fiber optic transmission and the other fields in the fiber optical communication u could try to realize or learn. recently,there (...)
Should it be mechanical ?? I think it's easier to shift 90 degree by converting optical-electrical-optical. There will certainly be a calibration mechanism but I guess mechanical shifting is harder due to small dimensions. Just an idea..
Hi I am looking for some document on optical fiber interface, so far I do not have much information about. If anyone knows any documents of link , please let me know it will be very useful. Thanks in advance Rahul J
Hello experts!! How are you all????? I have two question regarding with the fiber Optics. 1) I was reading in the book which I quoted below: optical fibers used in communication purposes follow wӗăkly guĭdĭng ăpproxĭmătĭon where the relative refractive index (delta) is much less than 1[/QUOT
Bandwidth offered by optical fiber communication is of the order of (A) 40 THz (B) 40 GHz (C) 40 MHz (D) 1010 Hz
hi all please i need your help. i want to simulate the effect of the polarization mode dispersion (PMD) of the optical fiber in OFDM system. thanks
Can any one help me to clarify why the fiber optical cable contains 144-fibers? Is there any theory behind it? and How many fibers used to connecting in a system?
During studying the telecom underground cable network I came across the optical fiber Cable having the 144 fibers (single mode). I want to know why 144? Is this a Some standard to have 144 fibers in one cable? I have also viewed some of the datasheet having 144 fibers optical (...)
Did you seen optical fiber you can send light at one end and get in other end, even it is curved or whatever the shape is.... An object in the water looks raised or bent dure to the diffraction of light when goes between two different mediums......
