ACX4000 Universal Metro Router

The ACX4000 Universal Metro Router is a 2.5U, actively cooled access router that is environmentally hardened for field deployment. This versatile, high-performance mobile access platform runs on the Junos operating system.

The ACX4000 has two modular interface card (MIC) slots that can house 16 T1/E1 ports, six GbE copper/fiber combination ports, or four CHOC3/STM-1 ports, creating a mobile access platform versatile enough for any deployment. Besides two MIC slots, the platform also provides a number of fixed ports that include 2 x 10GbE, 2 x GbE SFP, or 8 x GbE combination (copper/fiber).

This universal access routing solution is optimized to enhance the mobile subscriber experience while significantly improving network monetization for service providers.

Jackson Electric Co-Op Sees 30% Work-from-Home Internet Surge

When the coronavirus crisis forced the shutdown of America, Jackson Electric Cooperative turned it up. Broadband Internet became a lifeline for the residents of Matagorda Bay, Texas, in the U.S., with miles of Gulf Coast beaches and fresh oysters, blue crab, and shrimp. Jackson Electric’s smart community network, built on a foundation of Juniper routing, easily handled a 30% surge in Internet traffic and a 130% spike in subscriber connections.

Service Provider Security

Juniper Connected Security safeguards users, data, and infrastructure by extending threat intelligence to all connection points across your network.

State and Local Government

State and local governments have elevated their digital transformation priorities due to new challenges driving current events, such as constricted budgets and an unplanned distributed workforce.

Converged Industrial Edge

A growing number of single-purpose industrial and industrial IoT (IIoT) systems are converging onto Ethernet, IP, and MPLS. Juniper helps industrial companies meet system uptime and predictability service levels in the digital era.



Electric, gas, and water utilities rely on operational technology (OT) networks to support industrial control systems (ICS) essential to their businesses. Juniper’s comprehensive portfolio of resilient hardware, pervasive security, and specific automation ensures that safety and reliability are never compromised.

Oil and Gas

Oil and gas companies, like other industrial verticals, face many challenges on the journey to digital transformation. Modernized networks must seamlessly enable new, business-impact applications from the remote, operational edge to the cloud.
