SFP+ Direct Attach Cable BlueOptics SFP-10G-3M-WG 10GBASE-CR 3 m

SFP+ Direct Attach Cable BlueOptics SFP-10G-3M-WG 10GBASE-CR 3 m is a passive twinax copper cable with SFP+ form-factor connectors at both ends. It provides a cost-effective, low-latency 10 Gigabit Ethernet connection for short-reach links between switches, servers and storage devices. The 3 m length is intended for rack-to-rack or top-of-rack interconnects where fiber transceivers are unnecessary and direct electrical connection is preferred.

Advantages

This SFP+ direct attach cable offers a simple, plug-and-play solution for 10GBASE-CR links with reduced power consumption compared to active optical modules. The integrated SFP+ connectors eliminate the need for separate transceivers and patch cords, simplifying installation and lowering component count. The passive twinax design delivers consistent low latency and electrical performance over short distances and is suitable for dense, high-throughput environments.

Suitable for

• Rack-to-rack 10 Gigabit Ethernet connections
• Top-of-rack switch uplinks
• Server-to-switch and storage network interconnects
• Data center aggregation and spine-leaf short links

Key specifications

• Interface: SFP+ (dual-ended)
• Standard: 10GBASE-CR
• Length: 3 m
• Cable type: Passive twinax copper
• Data rate: 10 Gbps
• Typical use: Short-reach electrical interconnects
• Latency: Low, suitable for high-throughput applications

How to use

Insert each SFP+ connector into compatible SFP+ ports on the equipment until the latch engages. Verify link status on the connected devices and configure network interfaces as required. No additional transceivers, fiber patch cables or power sources are necessary for passive operation. For proper operation, ensure both devices support 10GBASE-CR over SFP+ direct attach cables and consult device vendor compatibility lists if needed.

Usage recommendations

Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius. Use appropriate cable management in racks to reduce strain on connectors and to keep airflow unobstructed. For installations in electrically noisy environments or distances beyond short-reach limits, consider using active optical modules and fiber instead.
