17.2.6 Amplified TDM Node
Figure 17-25
A hybrid line node is another example of the hybrid line amplifier OADM node. A hybrid line node is
single ONS 15454 node equipped with OPT-PRE amplifiers, OPT-BST amplifiers, and TCC2/TCC2P
cards for each line direction. Both types of amplifiers can be used or just one type of amplifier.
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. TDM cards can be installed in any
available slot. Review the plan produced by MetroPlanner to determine slot availability.
17.2.6 Amplified TDM Node
An amplified TDM node is a single ONS 15454 node that increases the span length between two
ONS 15454 nodes that contain TDM cards and optical amplifiers. There are three possible installation
configurations for an amplified TDM node. Scenario 1 uses client cards and OPT-BST amplifiers.
Scenario 2 uses client cards, OPT-BST amplifiers, OPT-PRE amplifiers, and FlexLayer filters.
Scenario 3 uses client cards, OPT-BST amplifiers, OPT-PRE amplifiers, AD-1C-xx.x cards, and
OSC-CSM cards.
The client cards that can be used in an amplified TDM node are: TXP_MR_10G, MXP_2.5G_10G,
TXP_MR_2.5G, TXPP_MR_2.5G, OC-192 LR/STM 64 ITU 15xx.xx, and OC-48 ELR/STM 16 EH
100 GHz.
