QSFP28 Connector 2x1-A1 WITH OUTER LIGHT PIPE
QSFP28 Connector 2x1-A1 Description
49012-00XXX1 is centered on a stacked 2x1 QSFP28 connector structure with outer light-pipe support, making visibility the defining add-on rather than thermal hardware. The 2 LP left-up arrangement gives the cage a more deliberate status-indication layout, while the narrow 19.8 mm width keeps the two-position stack compact across the panel.
With 38 circuits per port and 0.8 mm pitch, the cage is not just a mechanically stacked shell but a denser QSFP28 interface platform. For designs that want a two-high QSFP28 cage with outer light-pipe guidance and no added heat sink, this model is the cleaner and more visibility-focused choice.

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.
