1.2. Channel Insertion Loss (IL) Budget Calculation
The following figure is an example of a channel IL budget calculation for an end-to-end (TP0 to TP5) 200GBASE-CR4 channel, with the IL estimation at the Nyquist frequency for each channel component provided. Estimate the minimum and maximum insertion loss allocations for each component of the channel (from the transmitter to the receiver) to meet the link standard budget (for example, IEEE 802.3cd).
