  • Support for QSFP-100G-FR and QSFP-100G-LR transceivers (ACX5448, ACX5448-M, and ACX5448-D )—Starting in Junos OS Release 21.3R1, the ACX5448, ACX5448-M, and ACX5448-D switches support the QSFP-100G-FR and QSFP-100G-LR transceivers.

  • Support for passive optical network (PON) controller integration with 10G OLT SFP+ transceiver (ACX5448, ACX5448-M, and ACX5448-D routers)—Starting in Junos OS Release 21.3R1, the ACX5400 line of routers support the integration of the PON controller with Juniper Networks' 10GbE optical line terminal (OLT) SFP+ transceiver. This transceiver plugs into the 10GbE ports and instantaneously enables 10GbE symmetrical PON access on the router. Because the ACX5400 line of routers function as the OLT, the use of this transceiver eliminates the need for additional hardware. The following softwares are supported for Juniper's Unified PON in Junos OS Release 21.3R1:

    • PON Controller version R2.0.4
    • MicroClimate Management System PON Manager version R2.1.2
    • MicroClimate Management System NETCONF Server version R2.1.1
