17.1.6 Line Amplifier Node
A line amplifier node is a single ONS 15454 node equipped with OPT-PRE amplifiers or OPT-BST
amplifiers and TCC2/TCC2P cards. Attenuators might also be required between each preamplifier and
booster amplifier to match the optical input power value and to maintain the amplifier gain tilt value.
Two OSCM cards are connected to the east or west ports of the booster amplifiers to multiplex the optical
service channel (OSC) signal with the pass-though channels. If the node does not contain OPT-BST
amplifiers, you must use OSC-CSM cards rather than OSCM cards in your configuration. Figure 17-12
shows an example of a line node configuration.
