InfiniBand/fibre optic cable BlueOptics 49Y7886-LE-BL 1 m SFP+ Male/Male

The BlueOptics 49Y7886-LE-BL is a 1 m InfiniBand/fibre optic cable with SFP+ male connectors on both ends, designed for high-speed data transmission and reliable rack-to-rack or intra-rack connections. It supports 40G-class applications through a compatible wiring and connector arrangement and is intended for use in data centers and networking environments where SFP+ interfaces are available. The cable is a passive direct-attach style solution suitable for short-distance links and is produced to meet common MSA electrical and mechanical requirements for interoperability.

Advantages

This 1 m SFP+ male-to-male cable provides low latency and low power consumption for short-range high-speed links. It is designed to work with hardware platforms that support the corresponding 40G and 10G standards and follows established MSA guidelines so it interoperates with a wide range of switches, routers and storage systems. The construction uses quality components and is tested for compatibility, delivering stable electrical signal transmission for InfiniBand, Ethernet and Fibre Channel or FCoE applications where supported.

Suitable for

• Short-range connections between top-of-rack and adjacent-rack switches
• High-speed links in server and storage clusters using SFP+ ports
• InfiniBand, Ethernet or Fibre Channel / FCoE interconnects where SFP+ breakout is supported
• Data center rack cabling requiring passive direct-attach solutions

Key specifications

• Connector type: SFP+ male on both ends
• Cable length: 1 meter
• Supported protocols: InfiniBand, Ethernet, Fibre Channel and FCoE where supported by host hardware
• Transmission class: up to 40 Gbps aggregate using compatible breakout configurations
• Cable type: passive direct-attach (twinax style electrical interconnect for short distances)
• Typical power consumption: very low (passive design)

How to use

Install the BlueOptics 49Y7886-LE-BL by inserting each SFP+ connector firmly into the corresponding SFP+ port until the latch clicks. Ensure both connected devices support passive direct-attach twinax-style SFP+ connections and the intended protocol (Ethernet, InfiniBand or Fibre Channel). Use it for direct links within the same rack or to adjacent racks at distances appropriate for a 1 m passive cable. Verify link status and negotiate speed on the host devices after installation and, if necessary, follow platform-specific steps to enable passive DAC support in switch or server firmware.

Recommendations

Use this cable for short-distance, high-throughput connections where passive SFP+ direct-attach cabling is supported. Avoid route stress and tight bends; maintain the minimum bend radius specified by the platform vendor and avoid placing heavy loads on the cable or connectors. For critical deployments, test interoperability with your specific switch, router or storage platform and consider requesting a sample before large-scale rollout.
