Juniper EX4400‑48F 48‑Port Fiber‑Optimized Multispeed Ethernet Switch

The Juniper EX4400‑48F is a high‑performance, fixed‑configuration access and distribution Ethernet switch optimized for fiber‑only deployments in enterprise campus, branch, and high‑density environments. Powered by Juniper’s Junos OS, it supports advanced Layer 2 and Layer 3 networking features — including EVPN‑VXLAN, VLANs, MACsec encryption, QoS, routing, and automation — coupled with deep integration into Juniper Mist AI (Wired Assurance) for cloud‑managed insights and automated operations.

Designed for environments that require full fiber connectivity, the EX4400‑48F delivers 48× 1/10 GbE SFP/SFP+ fiber ports for high‑speed uplinks and server access without copper interfaces. This helps minimize cabling complexity and improve performance in backbone, server farm, and fiber‑centric access layers. Additionally, the switch includes 2× 100 GbE QSFP28 uplinks (or can be used with optional extension modules such as 4× 10 GbE or 4× 25 GbE) for flexible high‑capacity aggregation to core layers or fabrics. Redundant power supplies and hot‑swappable fans with airflow options deliver reliable operation in demanding rack‑based deployments.

Key Features:
• 48× 1/10 GbE SFP/SFP+ fiber ports for pure fiber access and uplinks.
• 2× 100 GbE QSFP28 uplinks for high‑bandwidth aggregation and spine connectivity.
• Advanced Layer 2/Layer 3 features including EVPN‑VXLAN, BGP, routing, QoS, and MACsec.
• Junos OS with Juniper Mist AI‑Driven Wired Assurance for automated management and telemetry.
• Redundant hot‑swappable power supplies and fans with configurable airflow.
