## Summary description

The BlueOptics X6566B-3-R6-BL is a 3 m InfiniBand/fibre optic cable with SFP+ connectors on both ends. It provides high-speed data transmission and is ideal for connecting network devices in data centers or high-performance computing environments.

## Long description

The BlueOptics X6566B-3-R6-BL InfiniBand/fibre optic cable is a 3 m connection cable with SFP+ connectors on both ends, engineered for high-speed data transmission in rack and short-reach environments. Designed to link switches, servers, storage arrays and other rack-mounted hardware, this cable supports 10G-class applications and is suitable for deployments where stable, low-latency links are required. The product is offered in black and follows industry MSA connector standards for interoperability with compatible SFP+ ports.
Advantages
This 3 m SFP+ cable provides reliable electrical twinax connectivity for short-distance links, delivering low latency and low power consumption compared to active optical alternatives. Passive construction reduces component complexity and offers a simple, robust solution for data center top-of-rack and adjacent-rack connections. Components and assembly are produced to meet common industry MSA specifications to maximize compatibility with major hardware platforms.
Suitable for
Short-reach 10G connections between switches and servers in racks
Interconnects between adjacent racks in data center environments
Storage systems and SAN links that accept SFP+ direct attach twinax connections
InfiniBand, Ethernet, FCoE and Fibre Channel setups within the supported 10G range
Key specifications
Connector type: SFP+ to SFP+ (both ends)
Cable length: 3 meters
Transmission class: up to 10 Gbit/s per link
Cable type: passive twinax copper (direct attach)
Wire gauge: 30 AWG
Color: black
MSA-compliant SFP+ form factor for broad compatibility
How to use
Identify two compatible SFP+ ports on your network devices, ensure the devices support passive direct-attach twinax cables, and insert each SFP+ connector into the respective port until it latches. No external power or configuration is required specifically for the cable; link activation and protocol settings (Ethernet, FCoE, Fibre Channel, InfiniBand) are managed by the connected devices. For best results, route the cable to avoid sharp bends and mechanical stress and verify link status through the hardware management interface.
Usage recommendations
Use this 3 m passive SFP+ cable for short, fixed connections inside racks or between adjacent racks. Confirm device compatibility with passive twinax DACs before deployment and avoid tight bend radii or kinking. For longer distances or active optical requirements, choose an appropriate optical transceiver and fiber solution.
