## Long description

BlueOptics Direct Attach Cable SFP-STACK-50 10GBASE-CR Passive, 5 m is a fixed-length passive twinax copper cable that provides a direct SFP+ to SFP+ 10 Gbps connection for short-range links. Designed for use between compatible SFP+ ports on switches, servers and storage devices, this 5 m cable delivers low-latency electrical connectivity without the need for separate transceivers. The cable is intended for rack-to-rack and intra-rack topologies where a compact, cost-effective 10GBASE-CR passive solution is appropriate.
Advantages
The passive twinax construction offers reduced power consumption compared with active modules and avoids the additional cost and inventory of separate transceivers and optical modules. A fixed 5 m length simplifies cabling planning for short links and minimizes signal attenuation over the intended distance. The direct-attach form factor ensures a consistent electrical interface for SFP+ ports, delivering predictable 10 Gbps performance and low latency suitable for high-throughput environments.
Suitable for
 Short-range 10G connections between switches within the same rack or adjacent racks
 Server-to-switch uplinks in data centers and server rooms
 Storage array connections requiring low-latency electrical links
 Environments where a cost-effective, passive SFP+ interconnect is preferred
Key specifications
 Cable type: passive twinax copper (direct attach)
 Interface: SFP+ to SFP+ (10G electrical interface)
 Data rate: 10 Gbps (10GBASE-CR compliant)
 Length: 5 meters
 Latency: low, suitable for short-range high-throughput links
 Form factor: fixed-length direct attach cable with integrated SFP+ connectors
How to use
Insert each SFP+ connector into the corresponding SFP+ port on the network device until it engages securely. Ensure devices are powered off or that hot-plugging is supported by the hardware and operating system before inserting or removing the cable. Verify link status and negotiate 10 Gbps operation in the device management interface or operating system network settings. Route the cable to avoid sharp bends and mechanical strain; maintain the recommended bend radius specified by the equipment manufacturer.
Usage recommendations
Use this 5 m passive SFP+ cable for short electrical links in controlled rack and cabinet environments. Avoid extended runs beyond the specified length and check compatibility with the device vendor's supported direct-attach solutions when strict interoperability certification is required.
