MPC5E-40G10G Juniper MPC5E 6x40GE + 24x10GE Line Card
Juniper MPC5E-40G10G Modular Port Concentrator
High-Density Mixed-Speed Line Card for MX240, MX480, and MX960 Routers
The Juniper Networks MPC5E-40G10G Modular Port Concentrator is a high-performance line card designed for Juniper MX-Series 3D Universal Edge Routers, delivering exceptional scalability, port density, and throughput for modern service provider and data center environments. Built on the advanced Juniper Trio chipset, the MPC5E-40G10G enables wire-rate performance for demanding Layer 2 and Layer 3 networking applications while supporting a wide range of advanced routing and switching services.
This powerful MPC combines 6 high-speed 40GbE QSFP+ ports with 24 10GbE SFP+ ports in a single slot, allowing network operators to efficiently consolidate high-bandwidth uplinks and dense 10G connectivity. With a total throughput of up to 480 Gbps (full duplex), the module is optimized for service provider cores, large-scale aggregation layers, and data center interconnect (DCI) deployments that require reliable high-capacity networking.
The MPC5E-40G10G supports advanced features such as Hierarchical QoS (HQoS), deep packet buffering, and inline traffic monitoring using J-Flow, ensuring superior traffic management and network visibility. Its QSFP+ interfaces also support breakout configurations, enabling additional flexibility to expand 10GbE connectivity where required.
For secure and scalable network operations, the module includes hardware-based MACsec encryption across all ports, protecting sensitive data with line-rate link-layer encryption. Fully integrated with Junos OS, the MPC5E-40G10G supports a broad range of networking technologies including MPLS, L3VPN, L2VPN, VPLS, and EVPN, making it an ideal solution for modern carrier and enterprise infrastructures.
Compatible with Juniper MX240, MX480, and MX960 routers, and requiring SCBE, SCBE2, or SCBE3 switch control boards for full bandwidth operation, the Juniper MPC5E-40G10G delivers the performance, reliability, and flexibility needed to power next-generation high-capacity networks.

FAQs:
Q1. Can the 40GbE QSFP+ ports be used as 10GbE ports?
Yes. By using QSFP+ to 4xSFP+ breakout cables or channelizing the ports in the Junos OS, each 40G port can be split into four 10G ports.
Q2. Does this MPC work in an MX960 with the original SCB?
No. To support the 480 Gbps throughput of the MPC5E, the chassis must be equipped with at least the SCBE (Enhanced Switch Control Board) or newer (SCBE2/SCBE3).
Q3. Is this line card hot-swappable?
Yes. Like all MX-series MPCs, the MPC5E-40G10G is hot-swappable, allowing for installation or removal without powering down the entire router.
Q4. Does this MPC require a specific version of Junos?
Yes. The MPC5E series typically requires Junos OS 13.3R1 or later. Always check the Juniper Hardware Compatibility Tool for the specific release required for your configuration.
Q5. Can I use this in an MX104?
No. This MPC is a full-height line card designed for the modular MX240, MX480, and MX960 chassis. It is not compatible with the smaller MX104 or MX204 fixed routers.
