shows the optical performance for 16-channel networks using SMF fiber. Span loss values
OADM nodes have a loss of 16 dB and equal span losses.
All nodes have OPT-PRE and OPT-BST/OPT-BST-E amplifiers installed.
The OPT-PRE amplifier switches to control power whenever the span loss is higher than 27 dB.
