The Juniper EX4400-48F delivers enterprise campus access over fibre where long runs and electrical isolation are important. With Layer 3 switching and stackable operation, it helps keep dispersed buildings and controlled spaces connected on a centrally managed platform.
As fibre-connected access layers expand across campuses and distributed sites, infrastructure teams need switching that keeps long runs manageable, electrically isolated and operationally straightforward.
The Juniper EX4400-48F is an access switch for production environments that need many 1GbE fibre endpoints with central management. It suits fibre-to-closet designs, remote plant areas and office risers where copper is not the right fit.
Its 48×SFP port layout supports high endpoint density, while 2×QSFP28 uplinks provide a practical path into aggregation. Stacking helps present multiple switches as one managed unit, and hot-swappable PSUs support maintenance without unnecessary interruption.
The result is a cleaner access layer for long-distance, electrically sensitive or cable-constrained environments. It helps reduce local complexity while keeping fibre endpoints on a platform suited to sustained operational use.
If you are planning fibre access at scale, our team can help assess where the Juniper EX4400-48F fits best and how to align it with your wider switching design.
Juniper EX4400-48F is an enterprise access switch for wired campus and branch environments, designed to provide a resilient platform for connecting users, devices, and downstream network services.
High-Density Fiber Access
The switch provides 48 SFP ports for fiber connectivity in access-layer deployments.
Uplink Expansion
Two QSFP28 uplinks provide higher-capacity connectivity for upstream aggregation and network growth.
Aggregation-Ready Throughput
A 456 Gbps switching capacity supports traffic handling across the access layer and its uplinks.
Enterprise Device Connectivity
The port mix is suited to connecting dense endpoint populations and building structured campus access designs.
Hot-Swappable Power Design
Hot-swappable PSUs help maintain service continuity during power module replacement.
Operational Continuity
The redundant power architecture reduces the risk of a single power-related interruption affecting the switch.
Managed Infrastructure Fit
The platform is built for enterprise switching environments where controlled deployment and stable operation are priorities.
Our team can help map EX4400-48F into access or aggregation designs where port density, uplink capacity, and resilient power need to align with campus requirements.

The Juniper EX4400-48F is a fibre access switch for environments that need many 1GbE endpoints over long runs, with centralised management and reliable access across buildings, risers and electrically challenging sites.
Hospitals with fibre-to-closet designs often need access switching for wards, theatres and diagnostic areas spread across separate buildings. The EX4400-48F fits where electrical isolation and long in-building runs matter more than copper access.
Financial campuses with fibre-connected desks, kiosks and risers need controlled access without relying on copper PoE density. The EX4400-48F supports these floors where distance, segregation and consistent switch management are operational priorities.
Energy and utilities teams commonly work in substations and control buildings where fibre is preferred for isolation and reach. The EX4400-48F handles many 1GbE fibre links without exposing the site to copper limitations.
Production sites with noisy machinery, separated control rooms and long cable paths need fibre access at the edge. The EX4400-48F suits these deployments when copper becomes harder to justify and access management must stay central.
Older office blocks and multi-floor workplaces often have fibre risers already in place, but still need a managed access layer for desks and downstream switches. The EX4400-48F reduces cabling disruption while keeping operations orderly.
Our team can help design and deploy Juniper EX4400-48F switching for hospitals, finance campuses, utilities sites, manufacturing plants and professional services buildings, with practical guidance on fibre access design and rollout.
