9.3.1    Optical Side Stages
 –
OPT-AMP-L, when provisioned in OPT-PRE (preamplifier) mode
 –
OPT-AMP-17-C, when provisioned in OPT-PRE (preamplifier) mode
 • OSC cards, such as:
 –
OSCM
 –
OSC-CSM
Table 9-1 shows the commonly deployed fiber stage layouts supported by DWDM mesh nodes. In the 
table, OPT-BST includes the OPT-BST, OPT-BST-E, and OPT-BST-L cards. OPT-AMP includes the 
OPT-AMP-L and OPT-AMP-17-C cards configured in either OPT-PRE or OPT-LINE mode.
Note In the table, L and C suffix is not reported because C-band and L-band amplifiers cannot be mixed in the 
same layout.
Table 9-1 Supported Fiber Stage Configurations 
Layout Cards Configurations
A OPT-BST <-> OPT-PRE/OPT-AMP 
(OPT-PRE mode)
 • OPT-BST OSC ports connected to OSCM OSC ports or 
OSC-CSM LINE ports
 • OPT-BST LINE ports connected to the span
 • OPT-BST COM-TX ports connected to OPT-AMP (OPT-PRE 
mode) or OPT-PRE COM-RX ports
 • OPT-AMP (OPT-PRE mode) or OPT-PRE LINE-TX or 
COM-TX ports connected to the next stage (for example, a 
40-WSS-C/40-WSS-CE COM-RX port in a ROADM node)
 • OPT-BST COM-RX ports connected to the next stage (for 
example, a 40-WSS-C/40-WSS-CE COM-TX port in a 
ROADM node) 
B OPT-AMP (OPT-BST mode) <-> 
OPT-PRE/OPT-AMP (OPT-PRE mode)
 • OPT-AMP (BST) OSC ports connected to OSCM OSC ports or 
OSC-CSM LINE ports
 • OPT-AMP (BST) LINE ports connected to the span
 • OPT-AMP (BST) COM-TX ports connected to OPT-AMP 
(PRE)/OPT-PRE COM-RX ports
 • OPT-AMP (PRE)/OPT-PRE LINE-TX/COM-TX port 
connected to the next stage (for example, a 
40-WSS-C/40-WSS-CE COM-RX port in a ROADM node)
 • OPT-AMP (BST) COM-RX port connected to the next stage 
(for example, a 40-WSS-C/40-WSS-CE COM-TX port in a 
ROADM node)
