Hello,


the best way to go is to request from the SP the information about the dampening of the specific fiber to be used. Usually this is measured during initial installation of the fiber. Once you have the value and also get the info about the other ends transmitter output power you can calculate the power your receiver has to expect. Compare it with the receiver specs and you will know whether an attenuator is needed or not.


Hope this helps! Please rate all posts.
