9.4 Configuring Mesh DWDM Networks
ONS 15454 shelves can be configured in mesh DWDM networks using the 40-WXC-C wavelength
cross-connect cards, multishelf provisioning, and the 40-channel patch panel, four-degree patch panel,
and eight-degree patch panels. ONS 15454 DWDM mesh configurations can be up to four degrees (four
optical directions) when the four-degree patch panel patch panel is installed, and up to eight degrees
(eight optical directions) when the eight-degree patch panel is installed. Two mesh node types are
available, the line termination mesh node and the cross-connect (XC) termination mesh node.
9.4.1 Line Termination Mesh Node
The line termination mesh node is installed in native Software Release 8.5 mesh networks. Line
termination mesh nodes can support between one and eight line terminations. Each line direction
requires the following cards: 40-WXC-C, 40-MUX-C, 40-DMX-C or 40-DMX-CE, a preamplifier and
a booster. Within this configuration, the following substitutions can be used:
• The 40-MUX-C cards can be replaced with 40-WSS-C/40-WSS-CE cards.
• The 40-DMX-C cards can be replaced with 32DMX cards, if a 32WSS is used.
• The 40-MUX-C cards can be replaced with 40-WSS-C or 32WSS cards.
• The OPT-BST cards can be replaced with OPT-AMP-C (in OPT-BST mode), OPT-AMP-17-C (in
OPT-BST mode) and/or OPT-BST-E cards.
• The OPT-RAMP-C can be added based on specific network design.
• The OPT-PRE can be replaced with an OPT-AMP-C (in OPT-LINE mode) OPT-AMP-17-C (in
OPT-LINE mode) card.
Each side of the line termination mesh node is connected as follows:
• The 40-WXC-C COM-RX port is connected to the preamplifier output port.
• The 40-WXC-C COM-TX port is connected to the booster amplifier COM-RX port.
• The 40-WXC-C DROP TX port is connected to the 40-DMX-C (or 32DMX) COM-RX port.
• The 40-WXC-C ADD-RX port is connected to the 40-MUX-C (or 40-WSS-C or 32WSS) COM-TX
port.
• The 40-WXC-C EXP-TX port is connected to the COM-RX through an LC-LC patchcord.
