| NCS1K4-QXP-K9 Line Card Support on NCS 1014 |
Cisco IOS XR Release 24.1.1 |
NCS1K4-QXP-K9 line card delivers low cost 100G and 400G DWDM transmission with ZR+ optics on a router. This line card can be used in both traditional Optical Networking solution and in Routed Optical Networking solution. This line card has 16 pluggable ports with eight QSFP-DD client ports and eight QSFP-DD trunk ports. For more information about the NCS1K4-QXP-K9 card, see the datasheet. |
The NCS1K4-QXP-K9 3.2T QSFP-DD DCO Transponder Line Card has eight client ports (QSFP-DD) and eight trunk ports (QSFP-DD ZR+). Each line card supports up to 3.2 Tbps traffic. The client rates that are supported are 400GE, 4x100GE, and 100GE Ethernet only. The modulation formats supported are 16 QAM for 400GE Txp/4x100GE Mxp.
The QXP line card provides up to 16 QSFP-DD ports (eight QSFP-DD client ports and eight QSFP-DD trunk ports). The supported operating modes are:
-
400GE-TXP
-
4X100GE MXP
-
2x100GE MXP
The QXP card has 8 slices. Each slice consists of one client and one trunk port with a slice capacity of 400G. The total capacity is 3.2T.

When you use OPENROADM trunk mode by configuring the trunk-mode OR command, use only alternate slices on the QXP card. Either use slices 0, 2, 4, 6 or 1, 3, 5, 7.
QDD-400G-ZR-S pluggable module supports FEC mode CFEC only.
QDD-400G-ZR-S pluggable module operates only as an Ethernet transponder.

DAC supported modes for NCS1K4-QXP-K9 card
DAC support is enabled on the NCS1K4-QXP-K9 card for 2x100G, 4x100G, and 400G operating modes.
This table provides the details of the respective DAC rates for the different trunk rates for NCS1K4-QXP-K9 card.

This example changes the DAC rate to 1x1.5 on an optics controller.
RP/0/RP0/CPU0:ios(config)#controller optics 0/0/0/0
RP/0/RP0/CPU0:ios(config-Optics)#dac-Rate 1x1.50
RP/0/RP0/CPU0:ios(config-Optics)#commit
Changing the DAC turns the laser Off and then back on for the optics. This is a traffic impacting operation.
The DAC rate configuration must match on both ends of a connection.
