SFP+ Direct Attach-kabel CBO JH697C 3 m sort

SFP+ Direct-Attach Cable CBO JH697C 3m Black is a pre-terminated copper twinax cable that provides a fixed, low-latency link between SFP+ ports on switches, routers and servers. At 3 metres length and with SFP+ compatible connectors, the cable is intended for short-range high-speed connections such as 10 Gigabit Ethernet in data centre and rack-to-rack environments. The black jacket offers a durable outer layer suited for rack cabling and frequent handling during installation.

Advantages

The cable delivers a ready-made high-bandwidth connection without the need for separate transceivers, reducing component count and power consumption. Its pre-terminated SFP+ connectors ensure consistent signal integrity and simplified installation. The fixed copper twinax design provides lower latency and lower cost for short-distance links compared with optical solutions, while the robust jacket and connector housings increase mechanical reliability in dense rack deployments.

Suitable for

• 10 Gigabit Ethernet short-range connections between network switches
• Rack-to-rack links inside data centres and server rooms
• Direct connections between blade server SFP+ ports and top-of-rack switches
• Low-latency, high-bandwidth links in clustered compute or storage systems

Key specifications

• Connector type: SFP+ pre-terminated twinax copper
• Length: 3 metres
• Color: Black
• Data rate support: 10 Gbps (SFP+ compatible)
• Physical form: Fixed direct-attach copper cable
• Typical use range: short-reach / within rack or between adjacent racks

How to use

Insert each SFP+ connector into the corresponding SFP+ port on network switches, routers or servers until the connector latches securely. Ensure ports are powered off or follow hot-plug procedures recommended by the equipment manufacturer if connecting to live systems. Verify link status using the host device’s management interface and confirm speed and duplex settings as needed. Route the cable to avoid sharp bends and maintain recommended bend radius for reliable signal performance.

Recommendations

For optimal performance, use the 3 m direct-attach cable for connections within the same rack or between adjacent racks. Avoid routing the cable alongside high-power electrical lines to reduce potential interference, and replace the cable if connectors show signs of wear or damage. Check compatibility with your equipment vendor for full SFP+ support and any specific port configuration requirements.
