What are the security issues facing data transmission in WDM domain which cannot be detected by OTDR?

How can carbon nanotubes be used to mitigate the dispersion effects in silicon based optical fibers?

Hi Anita, the main reason is unability to maintain bidirectional transmission with the required quality.

Carbon nanotubes can be used for laser pulse tuning and shaping which can give the compression of these pulse in time domain. Hence, the dispersion can be reduced or migitated.

Can it mitigate higher order dispersion?

I think that if an intruder performs a injection attack at the optical amplifier, the injected signal will amplify the incoming signal, which will over shadow the actual signal sent, thereby causing the effects like call drops which affects the quality of service.
