Imagine a data center that never slows down, even when traffic spikes. The Juniper QFX5240-64OD-AO 64-Port 800GbE OSFP Switch AC Air-Out is built for that exact need. It is a high-performance network switch that connects servers, storage and routers at blazing 800 GbE speeds. If you struggle with bottlenecks, limited port density or unreliable uptime, this switch removes those pain points and lets your network run smooth and fast.
Juniper QFX5240-64OD-AO 64-Port 800GbE OSFP Switch AC Air-Out
Large enterprises and cloud providers often face the problem of scaling bandwidth without adding bulky equipment. When traffic grows, old switches can become a choke point, causing latency and lost revenue. This switch solves the problem by offering 64 OSFP ports that each deliver 800 GbE, plus flexible breakout options for 400 GbE, 200 GbE or 100 GbE. The result is a single, compact chassis that handles massive data flows while keeping power use and space requirements low.
Key Features
- 64 OSFP ports each supporting 800 GbE.
- Breakout options: 64 800 GbE, 128 400 GbE, 256 200 GbE, 256 100 GbE.
- Two hot-removable AC power supplies with 1 + 1 redundancy.
- Four hot-swap fan modules with front-to-back airflow.
