DWDM Channel Allocation Plan

ONS 15454 DWDM multiplexer and demultiplexer cards are designed for use with specific channels in the C band and L band. In most cases, the channels for these cards are either numbered (for example, 1 to 32 or 1 to 40) or delimited (odd or even). Client interfaces must comply with these channel assignments to be compatible with the ONS 15454 system.

Table 6-4 lists the channel IDs and wavelengths assigned to the C-band DWDM channels.

Note

In some cases, a card uses only one of the bands (C band or L band) and some or all of the channels listed in a band. Also, some cards use channels on the 100-GHz ITU grid while others use channels on the 50-GHz ITU grid. See the specific card description or the “Hardware Specifications” document for more details.

Note

The Channel Number column is only for reference purposes. The channel ID is consistent with the ONS 15454 and is used in card identification.

Power Monitoring

Physical photodiodes P1 through P32 monitor the power for the 32MUX-O card. The returned power level values are calibrated to the ports as shown in the following table.

Table 8. 32MUX-O Port Calibration
Photodiode	CTC Type Name	Calibrated to Port

32DMX-O Card

The 32DMX-O card has reached end of support.

Note

For 32DMX-O card specifications, see the “32DMX-O Card Specifications” section in the Hardware Specifications document.

The 32-Channel Demultiplexer (32DMX-O) card demultiplexes 32 100-GHz-spaced channels identified in the channel plan. The 32DMX-O takes up two slots in an ONS 15454 and can be installed in Slots 1 to 5 and 12 to 16.

32DMX-O Card Functions

The 32DMX-O card functions include:

AWG that enables channel demultiplexing functions.
Each single-channel port is equipped with VOAs for automatic optical power regulation after demultiplexing. In the case of electrical power failure, the VOA is set to its maximum attenuation for safety purposes. A manual VOA setting is also available.

The 32DXM-O has four physical receive connectors that accept MPO cables on its front panel for the client input interfaces. MPO cables break out into eight separate cables.

Note

In contrast, the single-slot 32DMX card does not have VOAs on each drop port for optical power regulation. The 32DMX optical demultiplexer module is used in conjunction with the 32WSS card in ONS 15454 Multiservice Transport Platform (MSTP) nodes.

Each single-channel port is monitored using a photodiode to enable automatic power regulation.
Card level indicators— Table G-4 on page G-9

Port-Level Indicators for the 32DMX-O Card

The 32DMX-O card has five sets of ports located on the faceplate. MON is the output monitor port. COM RX is the line input. The xx.x to yy.y TX ports represent the four groups of eight channels ranging from wavelength xx.x to wavelength yy.y according to the channel plan.

Power Monitoring

Physical photodiodes P1 through P33 monitor the power for the 32DMX-O card. The returned power level values are calibrated to the ports as shown in Table 6-8.

4MD-xx.x Card

The 4MD-xx.x card has reached end of support.

Note

For 4MD-xx.x card specifications, see the section “4MD-xx.x Card Specifications” section in the Hardware Specifications document.

The 4-Channel Multiplexer/Demultiplexer (4MD-xx.x) card multiplexes and demultiplexes four 100-GHz-spaced channels identified in the channel plan.

The card is bidirectional. The demultiplexer and multiplexer functions are implemented in two different sections of the same card. In this way, the same card can manage signals flowing in opposite directions.

There are eight versions of this card that correspond with the eight sub-bands specified in Table 6-9 on page 6-13. The 4MD-xx.x can be installed in Slots 1 to 6 and 12 to 17.

4MD-xx.x Card Functions

The 4MD-xx.x has the following functions implemented inside a plug-in optical module:

Passive cascade of interferential filters perform the channel multiplex/demultiplex function.
Software-controlled VOAs at every port of the multiplex section regulate the optical power of each multiplexed channel.
Software-monitored photodiodes at the input and output multiplexer and demultiplexer ports for power control and safety purposes.
Software-monitored virtual photodiodes at the common DWDM output and input ports. A virtual photodiode is a firmware calculation of the optical power at that port. This calculation is based on the single channel photodiode reading and insertion losses of the appropriated paths.

Port-Level Indicators for the 4MD-xx.x Cards

The 4MD-xx.x card has five sets of ports located on the faceplate. COM RX is the line input. COM TX is the line output. The 15xx.x TX ports represent demultiplexed channel outputs 1 to 4. The 15xx.x RX ports represent multiplexed channel inputs 1 to 4.

Power Monitoring

Physical photodiodes P1 through P8 and virtual photodiodes V1 and V2 monitor the power for the 4MD-xx.x card. The returned power level values are calibrated to the ports as shown in the following table.

Table 11. 4MD-xx.x Port Calibration
Photodiode	CTC Type Name	Calibrated to Port
P1–P4	ADD	COM TX
P5–P8	DROP	DROP TX
V1	OUT COM	COM TX
V2	IN COM	COM RX

For information on the associated TL1 AIDs for the optical power monitoring points, refer the “CTC Port Numbers and TL1 Aids” section in Cisco ONS SONET TL1 Command Guide, Release 9.2.1.

Related Procedures for the 4MD-xx.x Card

The following is the list of procedures and tasks related to the configuration of the 4MD-xx.x card:

12-AD-FS Card

The 12-AD-FS card is a single slot add/drop card that provides colorless, contentionless, omnidirectional, and flex spectrum capability on 12 channels over 4 ROADM directions. The card receives the same wavelength from transponder cards and forwards it to different ROADM nodes without collision. This capability is achieved using multicast switches.

Each add/drop port pair in the card is:

Colorless - forwards any wavelength on a specific port
Contentionless - adds/drops the same wavelength from the same add/drop section to different directions
Omnidirectional - connects to both the add and drop directions

The 12-AD-FS card can be installed in any service slots in the Cisco NCS 2006 and NCS 2015 chassis. The 12-AD-FS card works only in the Cisco NCS Flex node.

Key Features

Integrates three independent add/drop sections that individually support add/drop of up to four channels over four ROADM directions. The channels can be forwarded to a direction only within the same section.
Provides add/drop sections, each of which has a 4 channel multiplexer and a 4 channel demultiplexer.
Monitors optical power on the input ports through optical photo diodes and raises alarms when the threshold is exceeded.
Supports tone detection on the input ports in the add direction.
Provides a multicast switch that does not block any wavelength and that does not have any optical filtering element.

For more information about the 12-AD-FS card, such as the block diagram and card specifications, see the data sheet.

16-AD-CCOFS Card

In this chapter, "16-AD-CCOFS" refers to the NCS2K-16-AD-CCOFS card.

The 16-AD-CCOFS card is a single slot add or drop card that provides colorless, contentionless, omnidirectional, and flex spectrum capability on 16 channels over 4 ROADM directions. The card receives the same wavelength from 16 transponder cards and forwards it to different ROADM nodes without collision. This capability is achieved using multicast switches. 2 or 3 16-AD-CCOFS cards can be connected using upgrade ports to provide the add/drop capability on 16 channels over 8 or 12 ROADM directions respectively.

Each add/drop port pair in the card is:

Colorless - forwards any wavelength on a specific port
Contentionless - adds/drops the same wavelength from the same add/drop section to different directions
Omnidirectional - connects to both the add and drop directions

The 16-AD-CCOFS card can be installed in any service slots in the Cisco NCS 2006 and NCS 2015 chassis. The 16-AD-CCOFS card works only in the Cisco NCS Flex node.

Key Features

Has a 16x4 multiplexer and a 4x16 demultiplexer.
Monitors optical power on the input ports through optical photo diodes and raises alarms when the threshold is exceeded.
Supports tone detection on the input ports in the add direction.
Provides a multicast switch that does not block any wavelength and does not have any optical filtering element.
Has fixed gain EDFA amplifiers in the add or drop directions to compensate for high optical insertion loss. The gain is -1 dB in the drop direction and -2 dB in the add direction.

For more information about the 16-AD-CCOFS card, such as the block diagram and card specifications, see the data sheet.
