  • Support for 400G ZR DWDM optics (MX2010, and MX2020)—Starting in Junos OS Release 22.2R1, we support 400G ZR DWDM optics. We support the following 400G ZR features:

    • 75-GHz grid spacing.

    • Optical loopbacks. To enable an optical loopback, use the existing loopback statement at the [edit interfaces optics-options] hierarchy level.

    • Performance monitoring and Threshold-crossing alert (TCA). You can view the current and historical performance monitoring metrics, which are accumulated into 15-minute and 1-day interval bins, by using the show interfaces transport pm command. You can thus manage optical transport link efficiently. TCAs provide the management system an early indication of the deteriorating health of an optical network connection when the performance parameter that you monitor crosses a certain threshold.

  • MPC7 and MPC5 support with SFB3 (MX2010 and MX2020)— Starting in Junos OS Release 22.2R1, we support MPC7 and MPC5 with the SFB3 Switch Fabric Board. The SFB3 interoperates with MPC11.

    [See MX2000 Switch Fabric Board (SFB) Overview.]

  • MPC2E and MPC3E support with SFB3 (MX2010 and MX2020)—Starting in Junos OS Release 22.2R1, we support MPC2E and MPC3E with the SFB3 Switch Fabric Board. The SFB3 interoperates with MPC11. This feature is supported only on Ethernet MICs.
