Juniper QFX5200-48Y-AFO Series 48-Port 25G SFP28 6x100G 3.6Tbps Ultra-Low Latency Switch - New

The Juniper QFX5200-48Y-AFO is a managed switch from the QFX5200 Series, built for spine-and-leaf IP fabric deployments and metro use cases needing native 25GbE port speeds with low latency. It draws air front-to-back, distinct from the reversed-airflow QFX5200-48Y-AFI sibling, sharing identical performance in either configuration. It provides 48 SFP28 ports, defaulting to 10 Gigabit Ethernet and configurable in groups of four for native 25 Gigabit Ethernet, alongside 6 QSFP28 ports that auto-detect transceiver speed for 40GbE or 100GbE operation. The switch delivers 3.6 Tbps of switching capacity and 2.1 Bpps of forwarding, backed by a 136,000 entry MAC address table. Management connectivity includes a Gigabit RJ-45 port with PTP Grandmaster support, a USB port, an RS-232 console port, and 2 additional SFP or RJ-45 management ports, of which only two can be active simultaneously. The switch draws power from a 650W AC or DC supply specific to the 48Y chassis, distinct from the higher-wattage supply used by the QFX5200-32C models, and runs the Juniper Junos operating system with base software services included.
