Juniper EX4300-48MP 4x 1G/10G SFP+ Uplink Module | Enterprise Switch

Add high-speed uplink headroom to EX4300 deployments with a 4-port 1G/10G SFP+ module designed for aggregation and upstream connectivity. When access ports are busy and east-west traffic grows, the right uplink module keeps the switching fabric from becoming the bottleneck. This module is a practical fit for campus access and distribution designs that need flexible optical uplinks without replacing the entire switch. The 1G/10G SFP+ interface support gives teams room to match current optics while preparing for higher-throughput links as network demand increases. That matters in environments where downtime, oversubscription, and forklift upgrades carry real cost. For infrastructure teams standardizing on Juniper EX4300 hardware, this module helps maintain a consistent platform while extending the life and utility of the switch. It is a focused expansion component, not excess hardware — exactly the kind of upgrade that improves network economics by adding capacity only where it is needed.
