Καλώδιο SFP+ BlueOptics JNP-SFP-DAC-1M-BL 1 m αρσενικό/αρσενικό

The BlueOptics JNP-SFP-DAC-1M-BL is a 1 meter SFP+ direct attach cable (DAC) with male SFP+ connectors on both ends. Designed for short-distance, high-speed links in racks and between adjacent racks, this passive twinax copper cable supports 10GBase-CR signaling and is compliant with MSA SFP+ form-factor specifications. The cable uses 30 AWG conductors and is intended for use in networking hardware that accepts SFP+ passive DACs, providing a simple, low-latency physical connection for switches, routers and storage systems.

Advantages

This 1 m SFP+ cable offers a cost-effective and energy-efficient interconnect for top-of-rack and adjacent-rack deployments. As a passive twinax solution it consumes no additional power, exhibits low latency and low failure rates due to its simple design, and is suitable for dense rack cabling where short reach, high throughput and predictable behavior are required. The cable’s construction follows common MSA guidelines and uses high-quality components to ensure reliable electrical performance and long service life.

Suitable for

• 10 Gigabit Ethernet links between switches and servers within the same rack or adjacent racks
• FCoE and Fibre Channel short-reach connections at 10 Gbit/s
• Connecting SFP+ ports on routers, storage arrays and network interface cards that support passive DACs
• High-density cabling in data centers and enterprise network closets

Key specifications

• Length: 1 meter
• Connector type: SFP+ male to SFP+ male
• Technology: Passive twinax copper (DAC)
• Data rate: up to 10 Gbit/s (10GBase-CR)
• Conductor gauge: 30 AWG
• Color: coral and silver
• Typical use: short-distance rack and adjacent-rack links
• Weight: approx. 0.08 kg

How to use

Insert each SFP+ connector into compatible SFP+ ports on the devices to be linked, ensuring the connectors click into place and the devices are powered and configured for 10GBase-CR or passive DAC operation. Verify the network interfaces are enabled and that firmware or operating-system settings allow passive DAC modules if vendor lock-in features are present. There is no separate power or transceiver module to install; the cable acts as a direct electrical connection between SFP+ cages.

Recommendations

Use this DAC for short links up to 1 meter and avoid running the cable across long distances or in place of fiber optics. Confirm device compatibility with passive SFP+ DACs and check port settings after installation. For high-density deployments, route cables to minimize bending and stress on connectors; avoid tight bends and maintain manufacturer-recommended bend radius.
