Does the different optical card work well?

[shan-cao]

Hi,I have two different optical card these are 15454E-L4.2-1= and 15454E-L4.1-1=. I don't know whether the different optical cards can communicate with each other. Pls help me! Besides, the distance between two different optical cards is about 35km. Thanks a lots.

Sincerely

15454E-L4.2-1= is 1550nm while 15454E-L4.1-1= 1310nm.

Both will not work together.
