in case of broad band connector, where the data is being transferred thorugh OFC, during this course a light enery is created for carrying data, whether this light energy is created by broad band connect or it is created by virute of functions of the subscriber or not?
in the caase of transmission of data of OFC, the data will be carried by light energy, how the light energy is created? whether it s created by broad band connector or subscriber itself?
