## Summary description

The BlueOptics CPAC-DAC-100G-5M-BL is a 5-meter InfiniBand/fibre optic cable featuring QSFP28 connectors on both ends. It is designed for high-speed data transmission in data centers and networking applications. This cable ensures reliable connectivity and optimal performance for demanding environments.

## Long description

The BlueOptics CPAC-DAC-100G-5M-BL is a 5 m QSFP28-to-QSFP28 direct attach cable (DAC) designed for short-distance high-speed data connections in data centers and network racks. As a passive twinax copper cable rated for 100GBase-CR4, it supports InfiniBand and Ethernet-class protocols and is intended for linking switches, routers, storage systems and other QSFP28-capable devices where a 5 meter direct connection is suitable.
Advantages
This 5 m QSFP28 twinax cable provides a cost-effective, low-latency connection for short-reach 100 Gbps links without active electrical components. The passive design yields very low power consumption and reduced heat generation compared with active optical transceivers. Constructed to meet MSA-compliant QSFP28 interface standards, the cable is produced using quality components and is tested for compatibility with major hardware platforms that support 100GBase-CR4 connections.
Suitable for
 Short-distance 100 Gbps links inside racks and between adjacent racks
 Connecting QSFP28 ports on switches, routers and storage arrays
 InfiniBand, Ethernet, FCoE and Fibre Channel applications up to 100 Gbps
Key specifications
 Cable type: Passive twinax copper direct attach cable (DAC)
 Connector type: QSFP28 male to QSFP28 male
 Length: 5 meters
 Data rate: Up to 100 Gbps (100GBase-CR4 / compatible protocols)
 Conductor gauge: 26 AWG
 Compliance: MSA-compliant QSFP28 form factor and electrical specifications
How to use
Insert each QSFP28 connector firmly into the corresponding QSFP28 port on the devices to be linked. Ensure both devices support passive DAC connections and the 100GBase-CR4 or equivalent protocol selected. Avoid bending the cable sharply; maintain manufacturer-recommended minimum bend radius and secure the cable to prevent strain on the connectors. After physical installation, verify link status and negotiated speed on both devices according to their management interfaces.
Usage recommendations
Use this 5 m passive QSFP28 DAC for intra-rack or adjacent-rack connections where short-reach, low-latency 100 Gbps links are required. Confirm device compatibility with passive 100GBase-CR4 twinax connections before deployment and follow equipment vendor guidance for supported cabling options.
