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 ACX7300 line is hardened, compact 3U (29cm deep), fixed plus modular platforms (supporting three I/O bays) that deliver high-performance access and aggregation routing optimized for space, power, and value. Next-generation silicon delivers 2.4 Tbps of throughput, a comprehensive feature set, exceptional 50GbE density (32 ports in 3U), and Media Access Control Security (MACsec) with support across all port speeds (1GbE to 400GbE). Combine these foundational capabilities with exceptional scale and highly flexible, build-as-you-grow port configuration and operators are equipped to evolve network protocols and features at their own pace. At the same time, they can support today’s most common transport upgrades without a platform forklift.

Resiliency and precision timing are also key attributes of the ACX7300 line and its role in Cloud Metro deployments. An optional, second routing engine (RE) card can be added to both platforms, enabling quick switchover from the active RE to the standby RE to prevent service interruption. The ACX7300 line supports up to eight fan trays (N+1 redundancy), four of which are field replaceable. Equipped with two –field-replaceable AC or DC power supplies (1+1 redundancy), a cost-effective and efficient thermal design enables unrestricted high-power ZR/ZR+ use across all supporting ports. Precision timing capabilities, including Class C timing and an integrated Global Navigation Satellite System (GNSS) , facilitate low latency services and dependable networking synchronization for consistent and reliable user experiences. The ACX7300 line supports next-generation protocols, including SR, SRv6, MPLS, Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN), and any overlay, underlay, or service. They deliver service-assured network slicing, network intelligence, and Juniper Paragon Automation for network efficiency and operational simplicity.

The ACX7332 and ACX7348 share identical features and capabilities while providing operators with key differentiators to fit the exacting needs of each deployment. The ACX7332 design includes onboard, eTCAM-enhanced scale and latency for E-Temp applications while the ACX7348 delivers 16 additional fixed ports for I-Temp applications.

ACX7332: The E-Temp-rated ACX7332 delivers high-end, eTCAM-enhanced, multiservices in a 3U, fixed plus modular, compact (29 cm deep), power-efficient footprint. It provides 2.4 Tbps forwarding capacity and supports 32 fixed multirate (SFP28) ports, each configurable as 1GbE, 10GbE, and 25GbE client services, enabling operators to perform today’s most common transport upgrades on a port-by-port basis without a platform forklift. An additional eight fixed (QSFP-28) ports support 100GbE (ZR capable) uplinks.

ACX7300 platforms have three I/O bays that provide support for optional interface modules covering a range of port speeds, one I/O bay delivers an additional 400 Gbps of capacity capable of supporting speeds from 1GbE to 100GbE. The other two I/O bays each provide an additional 800 Gbps of capacity capable of supporting port speeds from 10GbE to 400GbE. Integrated eTCAM technology facilitates the highest FIB scale, quicker lookups, and lower latency performance.

ACX7348: The I-Temp-rated ACX7348 delivers multiservices in the same 3U, fixed plus modular, compact (29 cm deep), power efficient footprint. It also provides 2.4 Tbps forward capacity, 48 fixed multirate (SFP28) ports, each configurable as 1GbE, 10GbE, and 25GbE client services, and eight additional fixed (QSFP-28) ports of 100GbE (ZR capable) uplinks. Three I/O bays support the same optional interface modules), one I/O bay delivering 400 Gbps of capacity supporting 1GbE to 100GbE port speeds. Two other I/O bays provide 800 Gbps of capacity each, supporting 10GbE to 400GbE ports speeds. Exceptional scale provides low-latency, high FIB and platform performance.

ACX7300 Interface Modules: The following modules can be used on both ACX7300 line platforms. Each module’s capability will be dependent on whether the module is used within one of the two 800 Gbps I/O bays or in the 400 Gbps I/O bay as noted.

• 16 ports, multi-rate 50GbE (SFP56) interface module, port-by-port configurable as 1GbE, 10GbE, 25GbE, and 50GbE NOTE: This capability applies when this interface module is used in either of the two 800 Gbps I/O bays. When used in the 400 Gbps I/O bay, optional native port speeds are 1GbE, 10GbE, and 25GbE.
• Four ports of 100GbE (QSFP28) and two ports of 400GbE (QSFP56) interface modules
  NOTE: This capability applies when this interface module is used in either of the two 800 Gbps I/O bays. When used in the 400 Gbps I/O bay, top port speed is 100GbE.
