The Juniper Networks MPC4E-3D-32XGE-SFPP Modular Port Concentrator is a high-density 10GbE line card designed for Juniper MX240, MX480, and MX960 routers, delivering exceptional performance and scalability for service provider and enterprise networks. With 32 SFP+ 10GbE ports in a single slot, this MPC enables efficient aggregation and core deployments, significantly increasing port density while reducing operational footprint.
Powered by the advanced Juniper Trio chipset, the MPC4E-3D-32XGE-SFPP provides wire-rate Layer 2 and Layer 3 forwarding, ensuring consistent performance even when running complex services. With a total throughput of up to 320 Gbps (full duplex), it is optimized for high-bandwidth environments such as ISP aggregation, metro Ethernet networks, and enterprise WAN edge deployments.
This line card supports a wide range of networking technologies including MPLS, VPLS, L2VPN, L3VPN, and Broadband Network Gateway (BNG) services, making it a versatile solution for multi-service edge architectures. It also features advanced capabilities such as Hierarchical QoS (HQoS), deep packet buffering, and inline traffic monitoring (J-Flow), enabling granular traffic management and enhanced network visibility.
The MPC4E-3D-32XGE-SFPP is compatible with a broad selection of SFP+ optics (SR, LR, ER, ZR) and DAC cables, offering flexibility for both short- and long-distance connectivity. Designed for efficiency, it delivers optimized power consumption per gigabit while maintaining high-scale routing table support.
When deployed in a fully populated MX960 chassis, this MPC can support up to 352 10GbE ports, making it an ideal solution for high-density, performance-driven network environments. Integrated with Junos OS, it ensures consistent operations, automation capabilities, and carrier-grade reliability across the network infrastructure.

FAQs:
Q1. Can I use this line card with the original MX Switch Control Board (SCB)?
While it may boot, the original SCB only provides 120 Gbps of fabric bandwidth per slot. To achieve the full 320 Gbps wire-rate performance, you must use an SCBE or SCBE2.
Q2. Does this MPC support 1GbE SFP modules?
Yes. The SFP+ ports are typically backward compatible with 1GbE SFP modules, allowing for a phased migration from 1G to 10G.
Q3. Is there a license required for the 32 ports?
No. The MPC4E-3D-32XGE-SFPP is fully featured; all 32 ports are active and available for use without additional per-port licensing.
Q4. Does this card support MACsec?
No. For hardware-based MACsec encryption at 10GbE density on the MX series, you would typically look at the newer MPC7E or specialized MIC modules.
Q5. Can I install this in an MX2010 or MX2020?
No. This MPC is designed for the MX240/480/960 form factor. The MX2000 series uses a larger form factor MPC (e.g., MPC6E or MPC11E).
