## Summary description

The BlueOptics QSFP28-DAC-1M-VA-BL is a 1 meter InfiniBand cable with QSFP28 male connectors. It provides high-speed data transfer and is ideal for connecting devices in data centers or high-performance computing environments.

## Long description

The BlueOptics QSFP28-DAC-1M-VA-BL InfiniBand Cable is a 1 meter passive direct attach twinax cable with QSFP28 male connectors at both ends, designed for short-range high-speed links in racks and between adjacent racks. It supports 100GBase-CR4 and InfiniBand applications up to 100 Gbps on a 1 m span and is MSA-compliant. The cable is intended for electrical signal transfer where a passive QSFP28 twinax solution is appropriate and is compatible with major hardware platforms that support QSFP28 direct attach copper links.
Advantages
This QSFP28 twinax cable provides a low-latency, low-power connection for high-throughput environments. As a passive DAC it requires no additional power for signal conversion and offers straightforward plug-and-play installation. The cable follows established mechanical and electrical MSA specifications for QSFP28 interconnects and uses high-quality components to ensure stable transmission and extended service life.
Suitable for
Short-reach 100 Gigabit Ethernet links in data center racks
InfiniBand high-performance computing interconnects
Connections between switches, routers and storage systems within the same rack or adjacent racks
Environments requiring low-latency, low-power cabling for server and network hardware
Key specifications
Connector type: QSFP28 male to QSFP28 male
Cable type: Passive twinax copper (DAC)
Supported data rates: up to 100 Gbps
Standard: 100GBase-CR4 / InfiniBand compatible
Length: 1 meter
Wire gauge: 30 AWG
Compliance: MSA-compliant mechanical and electrical characteristics
How to use
Ensure both devices support passive QSFP28 direct attach copper cables and the target protocol (100GBase-CR4 or InfiniBand). Power down or follow hot-plug guidance from your hardware vendor if required, then insert the QSFP28 connectors into the appropriate transceiver slots until they latch. Verify link status in the device management interface and confirm negotiated speed and protocol. For removal, follow the vendor-specific release procedure to avoid mechanical stress on ports.
Usage recommendations
Use this 1 m passive QSFP28 DAC for short, direct rack-to-rack or in-rack connections where low latency and low power consumption are priorities. Avoid routing the cable near strong electromagnetic interference sources and maintain bend radii consistent with twinax copper installation best practices. Verify vendor compatibility when deploying in mixed-brand environments.
