## Summary description

The BlueOptics S26361-F3873-L503-BL is a 3 m InfiniBand/fibre optic cable with SFP+ connectors on both ends. It features male/male connectors, ensuring reliable data transmission for high-speed networking applications. Ideal for connecting devices in data centers or high-performance computing environments.

## Long description

The BlueOptics S26361-F3873-L503-BL is a 3 m InfiniBand / direct-attach twinax cable with SFP+ male connectors on both ends. Designed for short-reach, high-speed connections, this passive 10G twinax cable supports 10GBase-CR electrical signaling and is compliant with SFP+ MSA guidelines. It is suitable for linking switches, routers, servers and storage devices inside racks or between adjacent racks where 3 m reach is required.
Advantages
This passive Direct Attach Cable (DAC) provides a cost-effective and energy-efficient solution for short-distance 10 Gbps links. Passive construction means no active electronics in the cable, resulting in low power consumption, low latency and reduced failure points. The 30 AWG twinax wiring and SFP+ to SFP+ interface follow MSA specifications to ensure interoperability with major hardware platforms that accept SFP+ passive DACs.
Suitable for
Short-reach 10 Gbps links inside racks and between adjacent racks
High-performance computing clusters and InfiniBand-capable systems
Switch-to-switch, switch-to-server and switch-to-storage connections
Data center patching where passive SFP+ DAC cables are supported
Key specifications
Length: 3 meters
Connector type: SFP+ male to SFP+ male
Data rate support: up to 10 Gbps
Cable type: passive twinax copper (30 AWG)
Supported protocols: Ethernet (10GBase-CR), FCoE, Fibre Channel and InfiniBand over short distances
MSA compliance: SFP+ DAC form factor and electrical interface
How to use
Install the cable by inserting each SFP+ connector into the corresponding module or SFP+ slot on the devices to be connected. Ensure both ports support passive 10G SFP+ Direct Attach Cables and that devices are powered down or follow hot-swap guidelines of the hardware when inserting modules. Verify link status through device LEDs or management interfaces and confirm negotiated speed and protocol settings in the network equipment configuration.
Usage recommendations
Use this passive SFP+ DAC for short, rack-level interconnects where 3 m reach is sufficient. Avoid tight bends and excessive mechanical stress on the cable; maintain manufacturer-recommended bend radius to ensure reliable signal integrity. Confirm hardware compatibility with passive DACs in the target devices before deployment.
