## Summary description

The BlueOptics DAC-Q28-100G-1M-BL is a 1m DAC cable featuring QSFP28 connectors on both ends. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable performance and minimal latency. The male/male configuration allows for easy connectivity between devices.

## Long description

The BlueOptics DAC-Q28-100G-1M-BL is a 1 meter Direct Attach Cable (DAC) with QSFP28 male connectors on both ends, designed for short-reach, high-bandwidth interconnects in racks and between adjacent racks. This passive twinax copper cable implements the 100GBase-CR4 electrical interface and supports data rates up to 100 Gbps over a 1 m distance. The cable uses 30 AWG conductors and follows MSA-compliant QSFP28 mechanical and electrical specifications to ensure interoperability with hardware platforms that accept QSFP28 passive DAC links.
Advantages
The cable offers low latency and low power consumption characteristic of passive DAC twinax solutions, delivering reliable 100 Gbps electrical connectivity without active components. Its 1 m length and QSFP28 male/male configuration provide straightforward, space-efficient rack connections for switches, routers and storage devices. Manufactured from high-quality components and tested for interoperability, the cable is intended to deliver stable performance and extended service life in data center environments.
Suitable for
 Short-reach 100 Gbps links inside racks and between adjacent racks
 Interconnecting QSFP28 ports on switches, routers and storage systems
 Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 100 Gbps
 Environments that require low-latency, low-power passive copper connections
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Length: 1 meter
 Data rate: up to 100 Gbps
 Cable type: passive twinax copper (DAC)
 Wire gauge: 30 AWG
 Compliance: MSA-compliant QSFP28 electrical/mechanical form factor
 Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand
How to use
Verify that both devices support passive QSFP28 DAC connections and the 100GBase-CR4 electrical specification. With powered-off or live hot-pluggable ports (depending on your equipment guidelines), insert each QSFP28 male connector into the corresponding QSFP28 port until the latch engages. Ensure cable routing avoids sharp bends and mechanical strain. For removal, depress the latch and withdraw the connector straight from the port. Follow your hardware vendor’s guidelines for hot-plugging and port configuration where applicable.
Usage recommendations
Use the cable for short-distance, high-throughput links inside racks or between adjacent racks. Avoid extended outdoor runs or long-distance links where optical transceivers or active cables are required. Maintain bend radius recommendations, keep connectors free from dust, and confirm port compatibility and firmware requirements on the connected devices to ensure reliable operation.
