[j-nsp] Juniper SONET OC48/192

[Andrew Jimmy]

Hi many thanks for your email. Yea we are looking for OTN type equipment
that insets colored laser directly into the DWDM system. Can you please give
us some insights in detail on it.

Second how much dB losses from transponder to PC-1OC192-SON-XFP PIC are
supported. It will work with -6 or -7 dBm or not. It would be nice if you
can describe this.

Once again thanks for your quick response.

Hello!

If you use PC-1OC192-SON-XFP with XFP-10G-L-OC192-SR1, you need a
transponder in the DWDM system, you can not insert the signal directly since
this type of XFP sends "normal" light. Same goes for PC-4OC48-SON-SFP with
the SFP-1OC48-SR.

The loss discussion is then not upto the XFP/SFP, since you need to use a
transponder in the system, and the DWDM system will be the source of the
colored light.

Are you indeed looking for OTN type of equipment that inserts colored laser
directly into the DWDM system?

Cheers
