QSFP28 1x1 Connector-C0
QSFP28 1x1 Connector-C0 Description
49003-00N011 is defined by a stripped-back single-port QSFP28 connector structure that keeps the hardware focused on the essentials: EMI finger support, press-fit mounting, and a standard 1x1 four-lane interface without any light pipe or heat sink. That makes it a cleaner option for designs that do not need added front-panel indication or extra thermal mass above the port opening.
With a 10.7 mm height and 61.3 x 20.54 mm footprint, this model stays more compact than heat-sink-equipped single-port variants while preserving the mechanical and shielding features expected of a QSFP28 connector. For layouts that prefer a straightforward 28Gbps QSFP28 port with fewer structural add-ons, this version is the more minimal 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.
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.
