Brand: Juniper Networks · SKU: QFX-EM-4Q · MPN: QFX-EM-4Q · Category: Networking
The Juniper QFX-EM-4Q is a high-performance expansion module designed for Juniper QFX5100 series modular switches, specifically the QFX5100-24Q and QFX5100-24S models. It adds four additional QSFP+ ports, each supporting native 40 Gigabit Ethernet (40GbE) connectivity, significantly increasing the port density and scalability of the host switch. The module is hot-swappable, allowing for insertion or removal without interrupting the switch's normal operation. It supports optical fiber media and is ideal for high-bandwidth data center and enterprise networking applications. Each 40GbE port can also be broken out into 4x10GbE SFP+ ports using splitter cables and optics.
