Juniper Networks ACX7509
Cloud Metro Router

Overview:

Network operators are finding incredible opportunities with 5G, IoT, and cloud, along with daunting challenges to support increasingly complex services and applications. The ACX7509 provides eight usable slots of high-density, low-speed fan-out, 1GbE to 400GbE port flexibility and scale in a reliable and compact 5 U, 60 cm deep footprint. Operational simplicity and an innovative fabric-less, centralized chassis architecture use fewer components, no fabric cards, and silicon-free line cards. This produces standout power efficiency, extended MTBF, and exceptional value for service provider, enterprise, wholesale, data center, residential, IoT, and 4G/5G use cases.

The Juniper Networks ACX7500 line multiservice routers is designed to help operators achieve their capital, operational, and differentiated user experience goals. Part of the Juniper Networks ACX7000 Family of routers, the ACX7509 delivers exceptional TCO, investment protection, and support for Juniper® Cloud Metro and 5G solutions, IoT, and cloud applications, making it ideal for service provider, large enterprise, data center, and residential deployments that require extremely power-efficient, high-density, and high availability (HA) platforms.

ACX7000 Family Overview

ACX7000 family of routers is purpose-built for the IP service fabric underlay of a Juniper Cloud Metro. They leverage the industry’s fastest chipset, provide a unique balance of system design, and set new benchmarks for sustainable, high-performance platforms. Managed by Junos® OS Evolved and Juniper Paragon™ Automation Portfolio, the ACX7000 routers are embedded with Paragon Active Assurance and with Zero Trust security built in, enabling operators to deliver highly differentiated customer experiences. Available in environmentally industrial-rated, fixed, fixed plus modular, and fully modular designs, these energy and footprint efficient multiservice routers support high-precision timing technologies and are engineered for service provider, enterprise, residential (including PON with the Juniper Unified PON Solution), IoT, and 4G/5G mobile applications.

Individually, ACX7000 platforms bring leading-edge performance, scale, and capability to any deployment. When building a comprehensive Juniper Cloud Metro architecture consisting of multiple ACX7000 family platforms, new dimensions of end-to-end operational capability, performance, and simplicity are realized. Forming the foundation of an IP service fabric underlay, the ACX7000 family of routers shares innovative features that elevate operations and enable the core characteristics of a Cloud Metro.

Product Offering

The ACX7509, from the ACX7500 line, is an 8-slot, 4.8 Tbps, modular, high-density multiservice router engineered to offer best-in-class performance, footprint, power efficiency, and scale. The innovative design approach includes centralized architecture for operational simplification and bandwidth flexibility, opening new possibilities for network transformation. The ASIC-free interface modules provide 1GbE, 10GbE, 25GbE, 40GbE, 50GbE, 100GbE, 200GbE, and 400GbE build-as-you grow port speed flexibility—ideal for high fan-out aggregation services and legacy network support use cases. 

Its breakthrough compact design with fabric-less architecture and fewer components, ICs, and ASICs sets new benchmarks for extremely low power consumption and TCO savings. Efficient cooling advances enable unrestricted use of high-power dense ZR/ZR+ transceivers on all supported ports in this fully redundant and high availability (HA) platform. Operators gain extended mean time between failures (MTBF) on an exceptionally small footprint consuming only 5 U and 60 cm deep of rack space, and a comparably simpler and less costly migration path to next-generation ASICs. ACX7905 platforms can realize a path to higher density, higher scale, higher port speeds, multiples of throughput, and future capabilities without a forklift or needing to change line cards, power supplies, and fans—as is necessary in competitive distributed chassis architectures. These improvements facilitate operational efficiency, investment protection, and radical capital and operational savings. ACX7509 capabilities also include Media Access Control Security (MACsec) on all ports, and the ability to seamlessly integrate with emerging distributed edge compute architectures.

ACX7509 supports three types of field replaceable FPCs for packet forwarding. These are installed vertically in the front slots of chassis and function as port extenders. 

• ACX7509-FPC20Y, a 500 Gbps throughput FPC that provides 20 ports of 1GbE, 10GbE, 25GbE, and 50GbE 
• ACX7509-FPC-16C, a 1.6 Tbps throughput FPC that provides 16 ports of 40GbE and 100GbE
• ACX7509-FPC-4CD, a 1.6 Tbps throughput FPC that provides 4 ports of 200GbE and 400GbE

Each FPC supports a variety of Ethernet port rates with different optics types. The ASIC-free port extenders deliver standout power efficiency and high value with port variety to meet growing network demands.

Designed for service providers, wholesale, large enterprise, and data center use cases, the ACX7509 is also a foundational building block of an IP services fabric in a Juniper® Cloud Metro solution.
