questions related to DWDM.......

What is impact of linear and nonlinear effects in DWDM network?

What are 3R, 2R and 1R?

What are types of Pluggable Optics?

What is common optical specification of Optical Transceiver (Pluggable Optics or Transponder)?

What is fixed optics?

If for point to point fiber link, two routers are connected and LX SFP used. If losses increased in fibre, what are possibilities to keep the link working? Want to connect client who is 300 kms apart. I don't want to use EoSDH. I have 1000base ZX SFP. Can I send my link using 5 amplifiers.

Explanation / Answer

Answer)

Due to high data rates for communications with high transmissions the nonlinear leads to unwanted effects like the Simulated Raman Scattering (SRS) and Cross phase modulations (XPM) and Four wave mixing (FWM)

Linear effects like attenuation, dispersion happens with respect to the DWDM network.

Hope this answer helps. :) Happy to help.
