Expansion module for Juniper MX routers

The Juniper MIC-3D-20GE-SFP-E is a 20-port SFP expansion module designed for Juniper MX Series routers. It adds high-density Gigabit Ethernet connectivity using 1000Base-X optical interfaces. Network operators use it to scale optical network capacity in service-provider and enterprise cores.

Thermals noise and power draw

The module weighs approximately 1.20 lb and fits into a standard MIC slot without external power cables. Passive cooling relies on the host router’s chassis airflow, so acoustic output matches the system’s existing fan profile. Power is drawn directly from the router backplane.

SFP flexibility and environmental compliance

Twenty SFP (mini-GBIC) slots accept a wide range of Juniper-qualified transceivers, letting you choose reach and fibre type per port. The assembly meets RoHS, WEEE and REACH environmental standards, simplifying deployment in regulated environments.

Questions about this item

How is the MIC-3D-20GE-SFP-E installed in a Juniper MX Series router, and what step is often missed?

Insert the module into an available MIC slot until the ejector levers lock, then secure both captive screws; the step often missed is tightening both screws to ensure proper electrical contact.

What maintenance or replacement will the 20 SFP ports need over time?

The SFP transceivers inserted into the 20 slots are hot-swappable and may need replacement if a link fails or when upgrading to different optical distances.

What throughput limit appears first when all 20 ports run at 1000Base-X line rate?

The module provides 20 Gigabit Ethernet ports; sustained full-duplex traffic on all ports is limited by the chassis fabric capacity of the specific MX router model.
