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)
