BlueOptics 693D1-BL InfiniBand/fibre optic cable 0.5 m QSFP28 Black

The BlueOptics 693D1-BL InfiniBand/fibre optic cable is a 0.5 m QSFP28 to QSFP28 direct attach cable (DAC) designed for short-range high-speed links in racks and between adjacent racks. This passive twinax copper-style assembly supports up to 100 Gbps data rates and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand protocols where QSFP28 connectivity is required. The cable uses a male-to-male QSFP28 connector configuration and is provided in black for standard data-center installations.

Advantages

The cable provides a compact, low-latency physical connection for 100G links, with passive operation that eliminates the need for additional power at the cable level. Manufactured to MSA-compliant QSFP28 specifications and assembled from high-quality components, it is built for compatibility with major network hardware platforms that support standard QSFP28 direct attach solutions. Its short length and twinax construction deliver low power consumption and low failure rates compared with active optical solutions for the same distance.

Suitable for

• Short-range 100G links between switches and servers in the same rack
• Inter-rack connections across adjacent racks in data centers
• High-throughput storage and SAN interconnects using Ethernet, FCoE or Fibre Channel
• InfiniBand fabric links requiring QSFP28 interfaces

Key specifications

• Connector type: QSFP28 to QSFP28, male/male
• Length: 0.5 meter
• Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand
• Data rate: up to 100 Gbps
• Cable type: passive direct attach twinax-style assembly
• Wire gauge: 30 AWG (typical for this class of DAC)
• Colour: black

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring secure latch engagement. Verify that both connected devices support passive QSFP28 direct attach cables and the intended protocol (Ethernet, FCoE, Fibre Channel or InfiniBand) at 100G. After physical installation, check link status on the devices and, if required, configure the interfaces according to the network setup and vendor guidelines.

Recommendations

Use this 0.5 m cable for direct, short-distance connections where a passive QSFP28 DAC is supported by the hardware. Avoid installing the cable in runs longer than the specified length and ensure ports and firmware of connected devices are compatible with passive QSFP28 assemblies to guarantee stable 100G operation.
