  • Supports flexible pay-as-you-grow configurations with modular interface design
  • Enables comprehensive Layer 3 routing for IPv4 and IPv6 traffic
  • Provides advanced hierarchical QoS per slot for service quality

HPE Juniper MIC3-3D-2X40GE-QSFPP expansion module

This module adds two 40 Gigabit Ethernet QSFP+ ports to compatible Juniper MX Series 3D Universal Edge Routers. It is built for network operators who need to expand high-density 40GbE connectivity in service provider or data centre environments. The unit functions as a Modular Interface Card (MIC) that slots into an MPC line module.

Practical limits of the 40GbE QSFP+ interface

Each port supports 40 Gigabit Ethernet speeds using QSFP+ transceivers and appropriate cabling. The interface does not support 100 Gigabit Ethernet or 10 Gigabit Ethernet directly without separate optics or breakout configurations not covered by this module. Maximum link distance and power budget depend entirely on the specific QSFP+ transceiver modules installed.

Installation fits MX Series MPC slots

The MIC installs directly into a compatible Modular Port Concentrator (MPC) slot on an MX Series router. No additional tools are required beyond standard rack access. The most common issue is inserting the card into an incompatible MPC generation or failing to seat the ejector levers fully, which prevents the router from recognising the module.

Questions about this item

Should I pick the MIC3-3D-2X40GE-QSFPP or a MIC with 10GbE or 100GbE ports for my MX Series router?

Choose this MIC when you need two 40GbE QSFP+ ports; select a 10GbE MIC for denser 10GbE connectivity or a 100GbE MIC for higher single-port throughput.

What does the 40GbE rating deliver inside an MX Series 3D Universal Edge Router?

Each QSFP+ port provides 40GbE line-rate forwarding for IPv4, IPv6, MPLS, Layer 2 switching and hierarchical QoS handled by the MPC packet forwarding engines.

What does the QSFP+ interface limit in practice?

The QSFP+ cages accept 40GbE transceivers and direct-attach cables, capping each port at 40GbE; they do not support 100GbE optics.
