QSFP28 Cage 1x1-A0 WITH HEAT SINK
QSFP28 Cage 1x1-A0 WITH HEAT SINK Description
49001-00N011 is defined by its single-port QSFP28 cage plus an ALUMINUM heat sink, making thermal support the key structural feature of the port rather than an added light-pipe or clip design. This gives the cage a more purpose-built shape for hardware layouts that want a standard 1x1 QSFP28 interface with extra metal mass above the cage opening.
The 16 mm height reflects that added thermal structure, while press-fit mounting and the EMI finger keep the design aligned with solder-free assembly and interface shielding. For equipment that needs a straightforward 1x1 QSFP28 cage with integrated heat-sink support and no extra visibility features, this version is the more targeted 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.
