The Juniper Networks MPC4E-3D-2CGE-8XGE Modular Port Concentrator is a high-performance, hybrid interface line card designed for Juniper MX240, MX480, and MX960 routers, enabling seamless transition from 10GbE to 100GbE networking. Combining 2 × 100GbE CFP ports with 8 × 10GbE SFP+ ports, this MPC delivers the ideal balance of high-speed core connectivity and dense aggregation in a single slot.
Powered by the advanced Juniper Trio chipset, the MPC4E-3D-2CGE-8XGE provides up to 280 Gbps full-duplex throughput with wire-rate Layer 2 and Layer 3 performance. It is engineered to support complex, high-scale networking environments such as service provider cores, enterprise WANs, and data center interconnect (DCI) deployments.
This versatile MPC is designed for networks undergoing bandwidth evolution, offering a flexible migration path to 100G while maintaining existing 10G infrastructure. The 100GbE CFP interfaces support optics such as LR4 for long-distance connectivity and SR10 for short-range deployments, while the SFP+ ports support a wide range of 10GbE optics and DAC cables for cost-effective connectivity.
With full support for MPLS, L2VPN, L3VPN, and VPLS, along with advanced features like Hierarchical QoS (HQoS), deep packet buffering, and inline traffic monitoring (J-Flow), the MPC ensures efficient traffic management and high network visibility. It also supports high availability features such as Graceful Restart and Nonstop Routing (NSR), ensuring uninterrupted service delivery in mission-critical environments.
Integrated with Junos OS, the Juniper MPC4E-3D-2CGE-8XGE provides consistent operations, automation capabilities, and carrier-grade reliability, making it an ideal solution for organizations looking to scale bandwidth while optimizing infrastructure efficiency.

FAQs:
Q1. Can the 10GbE ports be used as 1GbE ports?
Yes. The SFP+ slots are backward compatible with standard 1GbE SFP modules, providing flexibility for legacy equipment connections.
Q2. Does this line card support 40GbE?
No. This specific MPC model is dedicated to 100GbE (CFP) and 10GbE (SFP+) interfaces. For 40GbE requirements, the MPC5E or MPC7E series would be more appropriate.
Q3. Why does this card require an SCBE or SCBE2?
The aggregate throughput of 280 Gbps exceeds the 120 Gbps per-slot limit of the original MX Switch Control Board (SCB). An enhanced control board is necessary to provide the required fabric bandwidth.
Q4. Are the CFP optics hot-swappable?
Yes. Both the CFP and SFP+ optical transceivers are hot-swappable, allowing for maintenance or upgrades without impacting the other ports on the card.
Q5. Is this card compatible with the MX104?
No. This is a full-sized MPC designed for the modular MX240/480/960 chassis. The MX104 uses smaller, specialized MIC (Modular Interface Card) modules.
