Description

The Juniper MPC5E‑40G10G is a high‑density modular line card designed for use in Juniper MX Series routers, delivering extensive Ethernet connectivity and packet forwarding capabilities for service provider and enterprise networks. It combines both 40 Gigabit Ethernet (40 GbE) and 10 Gigabit Ethernet (10 GbE) ports in a single module, making it ideal for scaling network capacity without compromising on performance.

Capabilities:
This fixed‑port MPC (Modular Port Concentrator) supports up to six 40 GbE QSFP+ ports and twenty‑four 10 GbE SFP+ ports, with line‑rate throughput up to 240 Gbps. It supports full‑scale Layer 2 and Layer 2.5 forwarding, reduced‑scale Layer 3 routing, extensive queue management, and flexible PHY modes (LAN‑PHY and WAN‑PHY) per port. The card operates under Juniper’s Junos OS and maximizes routing capacity with support for up to 2 million FIB routes and up to 6 million RIB routes.

Use Cases / Deployment:
Ideal for large‑scale service provider edge, core backbone, and enterprise data center deployments, the MPC5E‑40G10G enables dense aggregation of high‑speed interfaces. Network architects deploy it where mixed speeds of 10 GbE and 40 GbE connectivity are required, such as in aggregation layers of IP networks, metro edge services, or high‑capacity WAN uplinks.

Integration:
The line card integrates with Juniper MX240, MX480, MX960 and MX2000 Series routers and works with Switch Control Boards (MX‑SCBE/MX‑SCBE2). It operates seamlessly with Junos OS and supports MPLS, VPN services (up to 32 L3VPN instances), advanced QoS, and traffic engineering features that tie into Juniper’s routing and service delivery ecosystem.

Key Features:

• High‑density mixed interfaces – 6× 40 GbE QSFP+ and 24× 10 GbE SFP+ ports for versatile connectivity.
• 240 Gbps line‑rate throughput – ensures full‑speed forwarding across all ports.
• Full L2/L2.5 and reduced L3 features – supports rich switching and routing capabilities.
• Large route capacity – up to 2 million FIB and 6 million RIB routes.
• Flexible PHY modes – LAN‑PHY and WAN‑PHY options per 10 GbE port.
• Advanced queueing – supports up to 32,000 queues per slot for QoS.
