BlueOptics M68FC-BL InfiniBand/fibre optic cable 1 m QSFP Male/Male

The BlueOptics M68FC-BL InfiniBand/fibre optic cable is a 1 m QSFP Male–Male cable designed for high-speed connections in data center and rack environments. The cable supports 40 Gbps class transmission and is intended for short-range links between switches, routers, storage systems and other networking equipment that use QSFP interfaces. With a compact 1 metre length and QSFP connectors on both ends, this cable provides a straightforward, low-latency link for dense rack deployments and adjacent-rack connections.

Advantages

The BlueOptics M68FC-BL offers a standardized QSFP to QSFP connection that is compatible with common 40GBase-CR4 and InfiniBand applications. Its 1 m length reduces excess cabling in racks and helps maintain signal integrity for short-distance, high-bandwidth links. Manufactured according to established MSA guidelines and using proven component types for twinax/DAC implementations, the cable is designed for reliable electrical transmission and low power consumption in passive configurations.

Suitable for

• Short-range 40 Gbps links between rack-mounted switches and servers
• InfiniBand connections in high-performance computing clusters
• Direct attach connections for storage arrays and SAN environments
• Adjacent-rack network interconnects in data centres

Key specifications

• Connector type: QSFP male to QSFP male
• Cable length: 1 metre
• Supported data rates: up to 40 Gbps
• Transmission medium: twinax / direct attach for short distances
• Passive cable design with low power usage and low latency
• MSA-compliant physical interface and pinout

How to use

Connect each QSFP end to the corresponding QSFP port on the devices you wish to link, ensuring that ports are powered down or in a safe state if required by your equipment vendor before insertion or removal. After physical connection, verify link status on both devices and configure the interface settings according to the network protocol in use (Ethernet, FCoE, Fibre Channel or InfiniBand). For passive direct-attach twinax operation, ensure the connected hardware supports passive DAC or compatible QSFP passive modules.

Recommendations

Use this 1 m BlueOptics QSFP cable for short, high-bandwidth interconnects inside racks or between adjacent racks. Avoid sharp bends and kinks, maintain recommended bend radius, and keep the cable clear of high-electrical-noise sources. Confirm device compatibility and supported link modes before deployment to ensure optimal performance and low latency.
