Fiber stage—The set of DWDM cards with ports that directly or indirectly face the span.
A/D stage—The add/drop stage.
TXP/MXP stage—The virtual grouping of all TXP or MXP cards with signals multiplexed or
demultiplexed to and from the physical fiber stage.
Booster amplifier cards that directly connect to the span, such as:
– OPT-BST
– OPT-BST-E
– OPT-BST-L
OPT-AMP-C, when provisioned in OPT-LINE (booster amplifier) mode
