Typical Applications

✅Data Center Server Aggregation: High-density 10GbE links between Top-of-Rack (ToR) switches (e.g., EX4300, QFX5100) and 10G NICs in servers or storage arrays using OM3/OM4 MMF.

✅Enterprise Network Backbone: High-speed 10G optical uplinks connecting EX series access switches to core/distribution layers over short-reach multimode fiber.

✅Service Provider & Cloud Infrastructure: Low-latency 10GBASE-SR interconnects for MX series routers and SRX firewalls within high-density telecom rooms and cloud facilities.

✅Campus & Data Center Migration: Ideal for upgrading legacy 1G SFP networks to 10G SFP+ performance while leveraging existing OM3/OM4 multimode fiber cabling infrastructure.
