Using DP04QSDD-HE0 to connect two routers (Point-to-point)

[M.Jallad]

Hello ,

Is it possible to use Cisco DP04QSDD-HE0 optics between two NCS 540 routers without using OLS (Mux/Demux or Amplifiers) for short (<80–100 km), clean dark fiber link ... i just want to use a single wavelength on this span.

Best Regards,

Thanks Marce,

I read that note , and thought i should make sure will it operate normally without pre-filtering a specific channel using (Mux/Demux) , since i will need to configure the router port on which i will plug the "DP04QSDD-HE0" for a specific frequency ?

for example : 

controller OpticalPort 0/0/0/0
frequency 193700

so i thought it should receive a specific wavelength first before entering the router port. So in the case of a dark fiber , should i configure a frequency as usual , and should it process it normally out of the whole range of frequencies . Is it true that all other channels will not have any dBm reported on the receiving end except for the one transmitted from the source. and would this affect the SNR of this channel if it's being transmitted this way ?

Yes, you can use the Cisco DP04QSDD-HE0 optics between  two NCS 540 routers over a short distance (less than 100 km) on a clean dark fiber link without the need for OLS (Mux/Demux or amplifiers), as long as the link is within the optics' supported range and the fiber is of good quality.

Just ensure the link meets the required specifications for signal integrity over the desired distance.
