InfiniBand/fibre optic cable BlueOptics 73930-0103-BL 3 m SFP+ Male/Male

The BlueOptics 73930-0103-BL is a 3 m InfiniBand/fibre optic cable with SFP+ male-to-male connectors designed for short-range high-speed connections in rack and adjacent-rack environments. It provides direct attach connectivity that supports up to 10 Gbit/s data transfer for Ethernet, FCoE, Fibre Channel and InfiniBand applications when used with compatible SFP+ ports. The cable is intended for professional networking hardware including switches, routers and storage systems that accept SFP+ direct attach or InfiniBand SFP+ modules.

Advantages

This 3 m SFP+ male-to-male cable offers a passive direct attach design that reduces power consumption and latency compared with active transceiver solutions. Manufactured to MSA-compliant specifications and using high-quality components, it is suitable for reliable short-distance links inside data centers. The cable supports common 10GBase-CR and InfiniBand signalling on compatible devices and is a cost-effective alternative to separate transceiver-plus-fibre assemblies for supported hardware platforms.

Suitable for

• Short-range 10 Gbit/s links between switches and adjacent racks
• Connections between servers and top-of-rack switches
• Storage systems and SAN interconnects using SFP+ or InfiniBand ports
• Data center patching and consolidation where low latency is required

Key specifications

• Cable length: 3 meters
• Connector type: SFP+ male to SFP+ male
• Supported data rates: up to 10 Gbit/s
• Cable type: passive direct attach (twinax copper / short-range InfiniBand/fibre optic direct attach application)
• Compliance: MSA-compliant SFP+ electrical specification
• Typical use: rack and adjacent-rack connectivity in data centers

How to use

Install the BlueOptics 73930-0103-BL by inserting each SFP+ connector into the corresponding SFP+ port on your devices until the latch engages. Ensure both endpoints support passive SFP+ direct attach or InfiniBand SFP+ connections and the chosen network protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). Route the cable to avoid sharp bends and maintain minimum bend radius specified by the manufacturer of the cable family. Power down is generally not required for hot-pluggable SFP+ modules, but follow your hardware vendor’s hot-plug procedures to avoid link negotiation issues.

Usage recommendations

Verify device compatibility before deployment: confirm that the network hardware and firmware accept passive SFP+ direct attach cables. For best performance, use the cable for short-range links (within rack or between adjacent racks) and avoid exceeding the 3 m length. Keep connectors clean and protected when not in use to preserve signal integrity.
