About the EX4400-48F
The EX4400-48F is the fiber model in Juniper’s EX4400 switch family. Its 36 1GbE SFP and 12 10GbE SFP+ ports suit a wiring closet or distribution layer where links arrive over fiber, and its two 100GbE QSFP28 ports work as uplinks or as Virtual Chassis ports, so up to 10 EX4400 switches can be managed as one.
Juniper rates it at 912 Gbps of switching capacity and 678 Mpps forwarding. An expansion slot takes an optional 4x10GbE or 4x25GbE uplink module, and every SFP and SFP+ port is MACsec capable. It runs Junos OS.
What’s included
- EX4400-48F switch with AC power and front-to-back airflow
- Standard Junos OS features, which need no license
Sold separately
- Optics and cables for the SFP, SFP+ and QSFP28 ports
- The 4x10GbE or 4x25GbE extension module
- MACsec (AES-256) license
- Advanced and Premium feature licenses and Juniper Care, listed in Support & Licensing above
Choosing a version
Every EX4400-48F version has the same ports. They differ in power and airflow:
- EX4400-48F (this page): AC power, front-to-back airflow
- EX4400-48F-AFI: AC power, back-to-front airflow
- EX4400-48F-DC: DC power, front-to-back airflow
- EX4400-48F-DC-AFI: DC power, back-to-front airflow
Match the airflow to your rack’s hot and cold aisles. For copper ports, see the EX4400-48T, the EX4400-48P (PoE) and the EX4400-48MP (multigigabit PoE).

Common questions
Does the EX4400-48F need a license?
No. Standard Junos OS features work without one. Advanced and Premium licenses add more features; the options for this model and their prices are in Support & Licensing above.
Are optics included?
No. Transceivers and cables are sold separately. Tell us the distance and fiber type and we’ll quote compatible optics.
Can I stack it?
Yes. Using its two 100GbE QSFP28 ports, up to 10 EX4400 switches can run as one Virtual Chassis.
What is the difference between the EX4400-48F and the EX4400-48F-AFI?
Only the airflow. The EX4400-48F moves air front to back; the EX4400-48F-AFI moves it back to front.
