  HiCoins as reward: 0 (problem unresolved)

How can I measure the OSNR performance of a DWDM channel before putting the actual OTN link? Like, trying to figure out how many MDU subracks I can go through without having to regenerate?

(Not having the OTN link means I can not obtain the OSNR from U2000, can I?)

Dear friend!
1. You can use the OD tool installed on the U2000 or NCE to perform the test. You can also use a dedicated meter to perform the test.

2. When no OTN link is available, you can use an optical power monitoring board (such as OPM8) to detect the OSNR of optical signals. 

3. For number of MDU subracks does the regeneration repeater need to be installed?

This is calculated based on the length of the optical link and the resulting OSNR penalty.
