QSFP28 Cage 1x4-B0 WITH HEAT SINK AND LIGHT PIPE
QSFP28 Cage 1x4-B0 Description
49007-00N011 is built around a four-port QSFP28 cage layout with 16 light pipes and an ALUMINUM heat sink, making it one of the more feature-complete horizontal cage formats in this group. The 1x4 arrangement pushes more ports into a single row, while the high light-pipe count supports clearer visual monitoring across all four openings instead of treating visibility as a secondary feature.
Its integrated heat sink adds another product-specific layer, giving the cage a stronger thermal identity than standard no-heat-sink multi-port versions. For designs that need a denser 1x4 QSFP28 front panel with both thermal hardware and broad light-pipe coverage, this model is a more specialized cage 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.
