QSFP28 Cage 2x1-P-D02 W-LPB
QSFP28 Cage 2x1-P-D02 W-LPB Description
49047-02XXX1 stands out by using a stacked 2x1 QSFP28 cage architecture with 38 circuits per port and a 0.8 mm pitch, giving it a denser electrical structure than the single-row 1x1 cage models. The two-port vertical arrangement keeps the horizontal panel span relatively narrow at 21.06 mm, which makes the part more attractive for designs that want stacked bandwidth instead of a wider single-row footprint.
Its 2 LP left-up light-pipe arrangement adds a specific visual feature without introducing a heat sink, so the design stays focused on stacked visibility and compact port organization. For hardware that needs a two-position QSFP28 stack with light-pipe guidance and a tighter front-panel width, this model offers a more targeted structure.

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.
