QSFP28 to RJ45 2x3-A0 Description

49031-00XXX1 is the more visibility-intensive 2x3 QSFP28 to RJ45 option, using both outer and inner light-pipe coverage across a six-position stacked cage. The 12 LP left-down arrangement gives the module a stronger status-indication focus than simpler stacked cages that rely on fewer or no light-pipe features, which is especially useful when six adjacent QSFP28 positions need clearer visual differentiation.

Because the cage does this without adding a heat sink, the structure stays centered on stacked density and optical indication rather than thermal hardware. For six-position QSFP28 arrays that need broad light-pipe coverage across the panel side, this model offers a more deliberately visibility-driven configuration.

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.

More Bandwidth per Port
QSFP-DD cage combines four electrical lanes in one interface, making it a stronger fit for platforms that need substantially more bandwidth per port than single-lane formats can provide.
Better Port Efficiency
Because one QSFP port can carry multi-lane traffic in a single housing, it helps equipment designers concentrate more throughput into a smaller front-panel area instead of multiplying lower-bandwidth ports.
Stronger Uplink and Fabric Fit
QSFP+ cage is commonly chosen for switch uplinks, aggregation paths, and fabric interconnects where traffic concentration is higher and the interface must support larger data flows than access-side ports.
Suited to Thermal and Signal Demands
High-bandwidth multi-lane links place greater demands on shielding, thermal control, and connector structure, making QSFP a more appropriate format for performance-oriented systems with heavier traffic loads.

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

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

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

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

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.

QSFP-DDCage FAQs

What is QSFP cage?

QSFP is a quad-lane pluggable interface format used for higher-bandwidth network links. It is commonly applied in switches, data center equipment, storage systems, and other platforms that require multi-lane connectivity.

How is QSFP to RJ45 different from SFP, SFP+, or SFP28?

The main difference is interface architecture. QSFP is built around four lanes in one port, while SFP, SFP+, and SFP28 are typically single-lane formats. This makes QSFP more suitable for higher aggregate bandwidth per port.

Why is QSFP often used for uplink ports?

QSFP is often selected for uplinks because uplink paths usually need to carry traffic collected from multiple lower-speed links. Its multi-lane structure helps support that higher-capacity role more efficiently.

Can QSFP-DD cage connector cages be customized?

Yes. QSFP connector cages can be customized based on application and design requirements, including structure, dimensions, mounting method, light pipe configuration, heat sink options, and other product details.
