SFP DAC kabel BlueOptics SFP-DAC50-BL 5 m SFP+ samec-samec

The BlueOptics SFP-DAC50-BL 5m SFP+ Male-Male is a passive SFP+ Direct Attach Cable (DAC) designed for short-range, high-speed connections in racks and between adjacent racks. This 5 meter twinax copper cable provides a direct SFP+ to SFP+ link supporting 10GBase-CR electrical transmission for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 10 Gbit/s. Constructed to MSA standards with 24 AWG twinax, the cable is intended for use with hardware that supports passive SFP+ DACs and offers low latency and low power consumption typical for passive twinax connections.

Advantages

The cable delivers reliable 10 Gbit/s connectivity over a 5 m distance while avoiding the need for separate transceivers, resulting in reduced power consumption and simplified installation. Built to MSA-compliant specifications and using high-quality components, it is suitable for continuous operation in data center and rack environments. Passive twinax copper design minimizes failure points and production complexity, offering a cost-effective alternative to active optical modules for short links.

Suitable for

• Connecting switches and routers within the same rack or adjacent racks
• Server-to-switch links in data centers
• Direct 10G connections for storage systems and SAN environments
• Short-range links for FCoE and Fibre Channel up to 10 Gbit/s

Key specifications

• Form factor: SFP+ to SFP+ male connectors
• Data rate: up to 10 Gbit/s (10GBase-CR)
• Cable length: 5 m
• Cable type: passive twinax copper, 24 AWG
• Power consumption: passive (approx. 0.1 W typical system-level savings versus active modules)
• Color: coral and silver
• Nominal weight: 0.18 kg

How to use

Install the BlueOptics SFP-DAC50-BL by inserting each SFP+ connector into the corresponding SFP+ port on your compatible devices until the latch clicks. Ensure both devices support passive SFP+ DAC cables and that firmware or vendor compatibility does not restrict direct-attach modules. Route the 5 m twinax cable to avoid sharp bends and excessive mechanical strain; secure as needed inside racks to prevent tension on connectors. No additional power or transceiver configuration is required beyond standard port setup on the connected equipment.

Recommendations

Use this passive SFP+ DAC for short-distance, high-throughput links inside racks or between adjacent racks. Verify device compatibility and, if possible, test a sample in your environment before large-scale deployment. Avoid repeated flexing and maintain bend radius per manufacturer guidance to preserve longevity.
