Channel Fiber Mode Rate Single mode Standard

AI Thread Summary

The maximum bit rate (bps) achievable over a 40 km long standard single-mode fiber using an ITU normalized channel with a 100 GHz optical bandwidth can vary significantly based on the chosen modulation formats. Advanced modulation techniques, such as QAM (Quadrature Amplitude Modulation), can increase capacity, while optical multiplexing can further enhance throughput. The use of electric modulation also plays a crucial role in optimizing performance. Factors like signal-to-noise ratio and dispersion must be considered to maximize efficiency. Overall, leveraging both electric and optical multiplexing alongside advanced modulation techniques is key to achieving higher data rates.

I have to find the maximun bps that it can be reach using a point-to-point link of 40 km long of optic fiber. I use an ITU normalized channel (100 GHz optic BW).

So, I can choose any electric modulation and any optic modulation, too.

Anybody could help me? Any answer is welcome. Thanks.

And I can use electric and optic multiplex, too.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
