QSFP28 2x1 Cage-P-E02 W-HS-LPB
QSFP28 2x1 Cage-P-E02 W-HS-LPB Description
49054-01XXX1 combines a stacked 2x1 QSFP28 connector layout with both an ALUMINUM heat sink and 2 light pipes, giving it a more hardware-rich structure than the simpler two-position stacked versions. The 32.95 mm height reflects this added build-up, making the part clearly oriented toward designs that need thermal metal above the cage together with visible port indication in the same stacked module.
Because it also uses 38 circuits per port, 0.8 mm pitch, press-fit mounting, and an EMI finger, the cage remains focused on high-density QSFP28 integration rather than just accessory add-ons. For systems that want a compact two-port vertical stack but also need thermal support and light-pipe visibility, this model is the more feature-loaded option.

Key Advantages of QSFP to RJ45 Connectivity
Built around a four-lane interface, QSFP-DD cage delivers higher aggregate bandwidth than single-lane pluggable formats and is widely used where uplink capacity, port efficiency, and dense high-speed connectivity matter most.
QSFP+ Cage Applications in High-Bandwidth Networks
QSFP+ cage is commonly used where multi-lane bandwidth is needed in a compact module format, especially in systems that rely on high-capacity uplinks, dense switching fabrics, and heavier east-west traffic.
Switch Uplinks and Aggregation Links
QSFP is widely used on uplink and aggregation ports where traffic from many lower-speed access ports must be concentrated into fewer higher-bandwidth interfaces.
Leaf-Spine and Data Center Fabrics
In data center switching architectures, QSFP fits naturally into fabric-facing connections that require higher throughput and efficient lane-based interconnect design.
High-Performance Storage and Backend Interconnects
QSFP cage is also suitable for backend fabrics that move large data sets between storage nodes, controllers, and high-throughput equipment where wider links are preferred.
HPC, AI, and Compute Clusters
Compute-heavy platforms such as HPC and AI clusters often need denser high-bandwidth node-to-node connectivity, making QSFP a practical option for multi-lane system interconnects.
