Juniper EX4300 EX-UM-8X8SFP 8x10G SFP+ 8x1G SFP | Enterprise Switch

Add high-speed fiber connectivity to EX4300 deployments without sacrificing access-layer density. The EX-UM-8X8SFP uplink module provides 8 x 10G SFP+ ports and 8 x 1G SFP ports, giving network teams the mix of bandwidth and compatibility needed for aggregation, uplink redundancy, and phased migration from 1 GbE to 10 GbE. This module is a practical fit for campus switching environments where uplink design matters as much as access capacity. It supports fiber-based connections for distribution closets, core handoffs, and server-adjacent switching, while keeping the platform aligned with Juniper EX4300 modular architecture. For teams standardizing on SFP optics, it offers a clean way to scale uplinks without replacing the switch. Compared with fixed-port alternatives, this module gives infrastructure teams more control over port mix and migration timing. That flexibility matters when you are balancing budget, optics inventory, and future bandwidth demand across multiple closets or buildings. For organizations that need dependable, high-density uplink options on an established switching platform, it adds meaningful value where it counts.
