## Long description

The BlueOptics QSFP28-100G-CU50CM QSFP28 100G 0.5m Blue is a passive copper direct attach cable (DAC) engineered for short-reach 100 Gigabit Ethernet interconnects. At 0.5 meters length, it connects QSFP28 ports between switches, routers, or network interface cards with low latency and high throughput. The cable’s robust housing and factory-terminated connectors provide a stable physical link suitable for dense rack environments and cable-managed installations.
Advantages
This QSFP28 100G 0.5m passive copper cable offers predictable electrical performance for short-distance links, minimizing signal loss and latency compared with longer or improperly matched copper assemblies. Its standardized QSFP28 connector format ensures compatibility with a wide range of QSFP28 ports and equipment that support passive DACs. The compact 0.5 m length reduces cable clutter in confined spaces, and the colored jacket aids visual identification within structured cabling systems.
Suitable for
 Short-reach server-to-switch or switch-to-switch 100G connections in data centers
 High-density rack deployments where cable management is critical
 Interconnects between QSFP28 network interface cards and top-of-rack switches
Key specifications
 Interface: QSFP28 to QSFP28
 Nominal data rate: 100 Gigabit Ethernet
 Length: 0.5 meters
 Medium: Passive copper direct attach
 Connector type: Quad small form-factor pluggable (QSFP28) metal housings

How to use
Insert each QSFP28 connector into the matching QSFP28 port until the latch engages; ensure ports are powered down or follow hot-plug procedures recommended by your equipment vendor. Verify link status through the switch or server management interface and confirm the interface negotiates at 100G. Route the 0.5 m cable to avoid tight bends and mechanical strain; use existing cable management pathways to maintain airflow and accessibility.
Usage recommendations
Use this passive QSFP28 DAC for short intra-rack or adjacent-rack connections where 0.5 m length is sufficient. Avoid exposure to conditions outside typical data center environments (excessive temperature, moisture, or mechanical stress) and follow equipment vendor guidance on supported passive cable types for full compatibility.
