Insertion loss is the amount of light lost (measured in dB), which is from the origination of a signal, to the reception of that same signal. Too high of an insertion loss will lead to, what is know as “channel errors”, that can cause equipment to go down, and possibly cause data center downtime. So It is important to know, the insertion loss of the products you are using, or considering purchasing.
