BlueOptics SFPP28-05-BL InfiniBand/fibre optic cable 5 m SFP+ Male/Male

The BlueOptics SFPP28-05-BL InfiniBand/fibre optic cable is a 5 m SFP+ to SFP+ direct attach cable designed for short-reach high-speed links in racks and between adjacent racks. It supports up to 10 Gbps data rates over a 5 metre channel and is intended for Ethernet, FCoE, Fibre Channel and InfiniBand applications where SFP+ interfaces are used. The cable conforms to common MSA dimensions and is compatible with major networking platforms that accept passive SFP+ direct attach twinax connections.

Advantages

This passive SFP+ direct attach cable offers low latency and low power consumption compared with active optical transceivers, while providing a cost-effective physical link for short distances. The design uses industry-standard SFP+ connectors at both ends for plug-and-play installation and is built from quality components to achieve stable signal integrity across the 5 m length. Its passive construction reduces points of failure and simplifies deployment in data center rack environments.

Suitable for

• 10GBase-CR direct attach connections between switches and servers within racks
• Server-to-storage links using SFP+ ports
• Short-reach InfiniBand and Fibre Channel interconnects up to 5 m
• High-density rack cabling where low latency and low power are required

Key specifications

• Connector type: SFP+ male on both ends
• Length: 5 metres
• Supported data rates: up to 10 Gbps
• Cable type: passive twinax direct attach
• Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand
• Designed for short-reach, rack-level interconnects

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on your network devices, ensuring secure latch engagement. Use this cable for direct attach links where both endpoints support passive SFP+ twinax connections and the transmission protocol (e.g., 10GBase-CR) is supported. No external power or transceiver modules are required; device ports must be configured according to the vendor’s guidelines for passive DAC operation.

Recommendations

Verify compatibility with your switch, router or storage vendor before deployment and test one cable in your environment if vendor-specific validation is required. Avoid sharp bends and excessive pulling; maintain manufacturer-recommended bend radius and rack routing practices to preserve signal integrity and cable lifetime.
